The Road to Rio+20 is the journey of countries in the world pursuing the sustainable development.As the first country to release the national Agenda 21,China’s experience and lessons are of great significance for both China itself and other countries.The paper reviews the progress made and problems remained in pursuing the sustainable development in China with regard to policy formulation,institutional arrangements,planning and management.In the past five years,the mandatory targets-driven approach,which focused on energy efficiency and key pollutants reduction,played a very important role and made China comprehensive outcomes for sustainability.In order to achieve the targets,China adopted an integrated policy package including legal,administrative,economic and technology instruments.During the 12th Five-Year Plan period(2011-2015),China will continue and strengthen the approach above and mainstream the transformation of economic development pattern through realizing the idea of green and low-carbon development.By summarizing policy trends in the world,the paper points out two directions,i.e.,integration approach and taking prioritized and concrete actions for a sustainable future beyond 2012.The paper also presents policy approaches and recommendations for sustainable development in the next 10 years in China. 相似文献

Metropolises are centers of politics, economy, culture and information, and also economic growth poles in comparatively large
areas. After 1949, China’s urban structure have changed greatly, from original "pyramid" shape into "upside-down pyramid"
shape, that is, more megalopolises and metropolises, fewer medium-sized and small cities. The most distinguishing feature
of urban population growth was the remarkable increase of population in megalopolises and metropolises. The key reason for
urban population expansion is to want to obtain the benefits of scale-agglomeration economy of metropolises. The number of
urban functions directly determines the quality and quantity of urban population. Metropolises appeal not only agricultural
population but also the population of medium-sized and small cities, which put much more population pressure on metropolises.
The ideal goals of scale-control of metropolitan population are discussed in terms of economy, society and ecollogy. In order
to control the metropolitan population expansion, the following measures should be taken: developing medium-sized and small
cities, and satillite cities establishing rationally regional urban system, reasonably distributing industrial enterprises,
and greatly developing township enterprises. 相似文献

Spatial and Temporal Variability of Thermal Stress to China’s Coral Reefs in South China Sea 总被引:2,自引:0,他引:2
Coral bleaching, caused by elevated sea surface temperature(SST), is occurring more frequently and seriously worldwide. Due to the lack of field observations, we understand little about the large-scale variability of thermal stress in the South China Sea(SCS) and its effect on China’s coral reefs. This paper used 4-km high resolution gap-filled SST(Filled SST) data and thermal stress data related to coral bleaching derived from Coral Reef Temperature Anomaly Database(Co RTAD) to quantify the spatial and temporal characteristics of chronic thermal stress and acute thermal stress to China’s coral reefs in SCS from 1982 to 2009. We analyzed the trend of SST in summer and the thermal stress frequency, intensity and duration during this period. The results indicate that, as a chronic thermal stress, summer mean SST in SCS shows an average upward trend of 0.2℃/decade and the spatial pattern is heterogeneous. Waters of Xisha Islands and Dongsha Islands of the northern SCS are warming faster through time compared to Zhongsha Islands and Nansha Islands sea areas of the southern SCS. High frequency bleaching related thermal stress events for these reefs are seen in the area to the northwest of Luzon Island. Severe anomaly thermal stress events are more likely to occur during the subsequent year of the El Nino year for these coral reefs. Besides, the duration of thermal stress varies considerably by anomaly year and by region. 相似文献

At present China is facing challenges from economic globalization, ecological economy and knowledge economy in its process
of economic development. The following ideas may be heuristic in establishing China’s regional development strategies: 1)
In locating industries, the impact of industries on the eco-environment should be fully considered. 2) Industrial restructuring
should be focused on the restructuring of products, not on the restructuring of the three traditional industries (primary,
secondary and tertiary industries). 3) The establishment of key industries should be focused on large-scale corporations or
famous brand products, not on a particular industrial sector. 4) The complementarity and cooperation between the east and
the west of China should be on products and markets, not on natural resources. The advantages in natural resources for the
west of China can not be over-estimated. The advantages in products and market potentials for the west of China may be explored. 相似文献

Comprehending regional characteristics and influencing factors of China’s inbound tourism economy is important to make effective
policies that will help inbound tourism develop harmoniously and shrink regional disparity. This paper studied the regional
disparity and convergence of China’s inbound tourism economy during 1996–2008 with the methods of σ-convergence, club convergence and β-convergence. The results indicate that 1) inbound tourism receipts per capita (ITRPC) of the whole country, the eastern,
central and western regions presented the rapid increasing trend; 2) ITRPC of the whole country was characterized by convergence;
3) the eastern region presented club convergence, but the central and western regions did not show this trend; 4) the star-hotel
levels and investment in fixed assets for the tourism industry per capita had a same trend to growth rates of ITRPC, promoting
inbound tourism development, and there was no difference among the 31 provinces (municipalities) in the mainland of China;
5) but the proportion of employed persons in the tourism industry accounting for total population and the proportion of the
tertiary industry accounting for GDP had a reversal trend to growth rates of ITRPC, shrinking the provincial disparity in
inbound tourism economy, and there were differences between the developed provinces and the developing provinces. Based on
these analyses, we put forward some suggestions for the developing provinces to speed up inbound tourism economy. 相似文献

Spatial interaction and network structure evolvement of cities in terms of China’s rail passenger flows 总被引:4,自引:1,他引:3
Cities separated in space are connected together by spatial interaction (SI) between them. But the studies focusing on the SI are relatively few in China mainly because of the scarcity of data. This paper deals with the SI in terms of rail passenger flows, which is an important aspect of the network structure of urban agglomeration. By using a data set consisting of rail O-D (origin-destination) passenger flows among nearly 200 cities, inter-city rail distance O-D matrixes, and some other indices, it is found that the attenuating tendency of rail passenger is obvious. And by the analysis on dominant flows and spatial structure of flows, we find that passenger flows have a trend of polarizing to hubs while the linkages between hubs upgrade. However, the gravity model reveals an overall picture of convergence process over time which is not in our expectation of integration process in the framework of globalization and eco- nomic integration. Some driven factors for the re-organization process of the structure of urban agglomeration, such as technique advance, globalization, etc. are discussed further based on the results we obtained. 相似文献

As a matter of expediency, most existing corporate-based urban networks can only be quantitatively measured by either counting the number of linkages or calculating the product of estimated service values. However, the impreciseness arising due to the limits of quantitative analysis may prove fatal to studies about non-market economies like China. Employing the capital investment dataset as an example, we build a capital-weighted intervention network as well as an unweighted control network to carry out an examination of the quantitative validity in China’s corporate-based urban network analysis. Both the overall spatial pattern and top city-dyads within the capital-weighted network witness Beijing, as the most dominant city, overshadow the performance of the others, and the unweighted network shows multilateral interactions between China’s top cities including Beijing, Shanghai, Shenzhen, and Guangzhou. To further interpret the noticeable differences, we divide the overall network into two subnetworks, inferred by focusing on state-owned enterprises(SOEs) and private enterprises. The results show that the public and private sectors have separately created vastly different subnetworks in China and that SOEs play a much more significant role in terms of capital. Besides fresh insights into China’s urban network, this study provides a cautionary tale reminding researchers of the essentiality and complexity when making a quantitative distinction between different linkages. 相似文献

Modern inbound tourism in China has been developing for 20 years, a trend line of inbound tourists in statistical data began
to show. This paper introduces the concept of tourism background trend line, and explores its two functions as a barometer
in demonstrating fluctuation in the tourism economy and as a forecaster in forecasting tourism development. The tourism background
trend line is a new concept, the word “background” derived from environment science, refers to the “trend line” which reflects
the dynamic curve or dynamic equation of tourism development without considering the impact of unexpected incidents. The introduction
of this concept was inspired by Karl Marx’s comments on the relation between value and price. Tourism background trend line
reflects the summary of multiple factors involving tourism resources, tourism demand, population growth, the scale and speed
of economic development, and the spatial interaction between tourism origins and destimations. It demonstrates the natural
and stable trend and the temporal law of tourism development in a country or region. The tourism statistical curve is at random,
susceptible to disruptions and disturbances from serious political, economic and environmental happenings, but it always fluctuates
around the background line. Tourism background line can reveal the potential of a country’s tourism development. Compared
with the statistical line, it can be used as a “barometer” indicating ups and downs of tourism industry in the past. When
naturally extended, the background trend line also can be used for forecasting the trend of tourism development in future.
In this paper, 4 tourism background trend lines of China’s inbound tourists, i. e. foreign tourists, Hong Kong/Macao/Taiwan
tourists, overseas Chinese tourists and total tourists from abroad, were established with statistical data from 1978 to 1996.
And the impacts of the Political Event in 1989 (or Tiananmen Square Incident) on China’s inbound tourism were evaluated. The
result shows that the impact of the Event was not limited within one year, but it stretched over 3 years. The total loss was
20 million in tourist arrivals and $1620 million in foreign currency income. The paper also studied the trend of China’s inbound
tourism in the next 4 years.

Under the theoretical framework of the New Trade Theory and the New Economic Geography, Home Market Effects (HMEs) is considered
to be important sources of comparative advantage and significant reasons for industry agglomeration. Through the analysis
on the input-output tables in China, the paper confirms the existence of HMEs for the manufacturing industries and their export
trades on the national and provincial level in China. Several conclusions have been drawn in this study. Firstly, there exist
prominent HMEs for manufacturing industries related with nondurable goods and materials in China. Secondly, 10 of the 15 kinds
of manufacturing industries considered in this study display the existence of HMEs. Thirdly, the comparative advantage of
factor endowment for the export trade of manufacturing industries is declining, while HMEs for them are increasing. Fourthly,
among the 30 provincial regions studied in this paper, 11 regions show the existence of HMEs, most of which are located in
the eastern coast region. This paper illustrates the simultaneous existence of the comparative advantage of factor endowment
and scale economies of HMEs for China’s manufacturing industries. HMEs will not only be the new dynamic for the increase of
manufacturing industries and their export trade, but also be the primary power for urban economic growth, industry improvement,
and urban space expansion for China. 相似文献

I Introduction Many of the world’s commercially important fishstocks are overexploited and some are even depleted(FAO 1997, 2005). Overcapacity is considered to be amain factor leading to such a tragedy (FAO, 1999). Con-sequently, the existence of excess capacity has been sin-gled out by FAO (1995, 1998, 1999) as a matter of grow-ing concern over the last decades or so. This represents amajor shift in the fishery policy at the international level,from focusing almost exclusively on the is… 相似文献

Based on development level of regional society and economy, the paper attempts to analyze the present situation, types and
change of regional environment in China through the definition of four conceptions environmental pollution index (EPI), social
and economic comprehensive index (SECI), —environmental comprehensive index (ECI) and social, economic and environmental comprehensive
index (SEECI) and some mathematical calculation, and draws some conclusions to be worth referring: 1). There exists close
relation between economic development and environmental situation. With high-speed development of economy, the discharge of
the three wastes in China has been increasing, but its environmental social and economic benefit has also been improved at
the same time. 2) In the course of economic development, regional environment situation in China has continuously been changing,
and there exists the difference of environmental quality between provinces, which is bigger than that of economic development
level between them. 3) Except very few provinces, regional EPI in China has risen in varying degrees since the 1980s, which
shows that the task for China to prevent environment from polluting its still arduous. 相似文献

Since China’s reform and open-door, the countries and regions of direct investment in China’s mainland have been increasing.
In 1995, the amount of foreign direct investment (FDI) in China was US$ 37.81 billion that was from more than 170 countries
and regions. The regional structure of capital market of FDI in China has three characteristics: (1) The most of FDI was from
the near countries or regions, Hong Kong-Macao, Taiwan, Japan, South Korea, Thailand and Malaysia provided 80.3% of the amount
of FDI in 1995. (2) Only several countries and regions provided most of FDI in China. (3) According to the contributory rate,
the main capital market of FDI in China could be divided into four classes, including the guiding market, subsidiary market,
new and development market, opportunity market. Most of FDI in China was from the developing countries and regions, which
had a negative effect on the size and technical level of foreign capital enterprises. The author puts forward the countermeasures
to improve the regional structure of capital market: (1) to keep the guiding market stable, (2) to open up chiefly the subsidiary
market, (3) to guide actively the new and developing market, (4) to try hard to start the opportunity market. 相似文献

Tourism resource assessment and spatial analysis of wine tourism development: a case study of the eastern foothills of China’s Helan Mountains 总被引:1,自引:1,他引:0
The reasonable development and utilization of mountainous regions closely relates to local economic development and ecological security. The wine production region in the eastern foothills of the Helan Mountains in Ningxia, Ningxia Hui Autonomous Region, with its excellent terroir, is emerging as one of China’s three major geographical attractions. Based on surveys of tourism resources and spatial analysis for this wine producing region, we propose a highly representative and practicable path for wine tourism development. Based on China’s national standard in Classification, Investigation and Evaluation of Tourism Resources (GB/T 18972-2003), which recommended the types and grades of tourism resources in one area, we conduct an analysis of resource characteristics and the current state of development. Using ArcGIS software, spatial autocorrelation analysis, average nearest neighbor analysis, as well as clustering and outlier analysis, we are able to derive the spatial distribution characteristics of tourism resources. Our survey showed that tourism resources in this area are relatively abundant and have good quality and clear combination advantages. Nonetheless, there are resources shortage for wine tourism and poor integration of wine production with the tourism industry. Regarding the spatial distribution of resources, we revealed the current states of and issues surrounding regions with concentrated resources, as well as characteristics of this clustering. Finally, we proposed a development path for wine tourism in this region based on the five dimensions of management mode, industrial path, product development, spatial optimization, and market development. 相似文献

By analyzing the relationship among government, market driving forces, distribution orientation of banking industry, service
opportunity equality and spatial patterns, this paper proposes that it is distribution orientation that lead to the formation
and evolution of spatial pattern of banking industry. The difference of the distribution orientation leads to the separation
of the spatial pattern of banking industry, and the change of the distribution orientation leads to the change of spatial
pattern. The degree of spatial pattern change is subject to the degree of change of distribution orientation, and the scale
of bank resources in the regions, which supports the distribution orientation variation. Based on these theoretical frameworks,
some indicators were designed to analyze the pattern change of China’s banking industry and its effects since 1995 under the
change of the distribution orientation. This paper finds that the orientation of economic benefit maximization driven by market
causes the banking industry to concentrate in economically developed regions. The government, which does not follow the orientation
of economic benefit maximization, plays a role of stabilizer. Since the bank branches in the regions with the greatest change
in bank branch distribution are too few, and regions with the greatest change in bank loan allocation are the regions with
lots of loans, the pattern change of the banking industry in physical form is not as notable as that in economic form. 相似文献

Black carbon and polycyclic aromatic hydrocarbons (PAHs) in surface sediments of China’s marginal seas 总被引:8,自引:0,他引:8
This study investigates the distribution of black carbon (BC) and its correlation with total polycyclic aromatic hydrocarbons (ΣPAH) in the surface sediments of China’s marginal seas. BC content ranges from <0.10 to 2.45 mg/g dw (grams dry weight) in the sediments studied, and varied among the different coastal regions. The Bohai Bay sediments had the highest BC contents (average 2.18 mg/g dw), which comprises a significant fraction (27%–41%) of the total organic carbon (TOC) preserved in the sediments. In ... 相似文献

Articulating China’s Science and Technology: Knowledge Collaboration Networks Within and Beyond the Yangtze River Delta Megalopolis in China 总被引:1,自引:0,他引:1
In this paper, we reconsider the defining but often overlooked ‘hinge' function of megalopolises by analyzing how megalopolises have articulated national and international urban systems in the context of a globalizing knowledge economy. Taking the case of China's Yangtze River Delta(YRD) region, we particularly focus on knowledge circulation within and beyond the YRD region by analyzing the pattern and process of knowledge collaboration at different geographical scales during the 2004–2014 period. Results show that the structure of scientific knowledge collaboration as reflected by co-publications has been strongest at the national scale whereas that of technological knowledge collaboration as measured by co-patents has been strongest at the global scale. Despite this difference, the structure of both scientific and technological knowledge collaboration has been functionally polycentric at the megalopolitan scale but become less so at the national and global scales. The ‘globally connected but locally disconnected' pattern of Shanghai's external knowledge collaboration suggests that the gateway role of the YRD megalopolis in promoting knowledge collaboration at different geographical scales will take time before it is fully realized. 相似文献

Market-based emission trading schemes (ETSs) are widely used in the developed world to reduce greenhouse gas (GHG) emissions which are perceived as the source of global climate change. China, as the largest GHG emitter in the world, is committed to introducing an ETS to reduce emissions. Here we reviewed existing ETSs and sustainable energy policies worldwide as well as China’s pilot programs. These studies were conducted in order to propose recommendations for national initiatives and strategies to be implemented in China in relation to climate change adaptation and mitigation. It has been shown that setting emission caps in the context of a national emission intensity target is difficult. However, implementing reliable systems for measurement, reporting, and verification of emissions are essential. A two-level management system (by central and provincial governments) for carbon trading is beneficial to ensure uniform standards and compliance while maintaining flexibility. Persistent political support from, and effective coordination of, policies by the government are crucial. In addition, strengthening of institutional innovation, and the establishment of a national GHG emissions information system, are of equal importance. This vital information could provide a great opportunity for China to re-define its economic growth and take global leadership in combatting climate change. 相似文献

Landslide inventory plays an important role in recording landslide events and showing their temporal-spatial distribution. This paper describes the development, visualization, and analysis of a China's Landslide Inventory Database (CsLID) by utilizing Google’s public cloud computing platform. Firstly, CsLID (Landslide Inventory Database) compiles a total of 1221 historical landslide events spanning the years 1949-2011 from relevant data sources. Secondly, the CsLID is further broken down into six zones for characterizing landslide cause-effect, spatiotemporal distribution, fatalities, and socioeconomic impacts based on the geological environment and terrain. The results show that among all the six zones, zone V, located in Qinba and Southwest Mountainous Area is the most active landslide hotspot with the highest landslide hazard in China. Additionally, the Google public cloud computing platform enables the CsLID to be easily accessible, visually interactive, and with the capability of allowing new data input to dynamically augment the database. This work developed a cyber-landslide inventory and used it to analyze the landslide temporal-spatial distribution in China. 相似文献

China’s potential of grain production due to changes in agricultural land utilization in recent years 总被引:3,自引:1,他引:2
The changes in utilization of agricultural land have gradually grown into one of the major factors impacting grain output in China. This study explores the various components of agricultural production in China from the land utilization perspective, involving changes in grain production per unit area, multi-cropping index, and adjustment of agricultural structure. Compared with the record values, different research methodologies are used to analyze the potential of above three components. The results indicate that grain production potential of 65.68×109kg was unexploited in 2006, in which 45.8×109kg came from the restructuring in agriculture. So we can infer that the reduction of grain production in China could be primarily attributed to agricultural restructuring in recent years. So the productive potential can be fully restored by increasing agricultural investment, or recovering agricultural structure in favorable conditions. So we can say that China's current condition of food security is good. 相似文献
