FORGING ASIA＇S GLOBAL TRANSPARK IN THE PEARL RIVER DELTA AT ZHUHAI

The main purpose of the paper is to introduce the concept of the Global TransPark (GTP). It is a critical time to develop air logistics infrastructure in the New Economy. The paper also presents a brief review of the air cargo industry in the Asian-Pacific region and China, in particular China‘s development in the industry as its economy has grown rapidly and globalized in the past two decades. The paper argues that China needs to develop a GTP to support its future growth, and explains why the Pearl River Delta-Hong Kong-Macao city-region or Extended Metropolitan Region (EMR) is the best location. Finally, it proposes that Zhuhai Airport, one of the five airports in the EMR, is thebest site for the GTP. New policies from Chinese government as well as close cooperation between local governmentsof Guangdong and the two Special Administrative Regions of Hong Kong and Macao will be needed to make the establishment of the GTP possible.     

Identification and comparison of aircraft industry clusters in China and United States

Aircraft industry is very important to the economy and security of a country, and aircraft industry clusters have already existed in the world. Based on Input-Output data and Czamanski’s method, the aircraft industry clusters in China and USA were identified quantitatively in this paper. Furthermore, this article carried out comparison analyses of the identification results. The research finds out: 1) a mature aircraft industry cluster would be generally composed of 7 industrial subgroups, including aircraft industry, metal making and products manufacturing industry, machinery and equipment industry, electronics industry, automobile industry, material industry and others, and electronics industrial subgroup will play a more and more important role in the cluster; 2) in the range of industry-covering, the level of industry-linkage, and the economic performance, there is a tremendously large gap between the aircraft industry cluster of China and that of USA; 3) the spatial evolution of these clusters or centers is highly consistent with the diffusion of a country’s industrialization. Finally, based on those findings, the paper gives some advice on how to improve Czamanski’s method and what China should do to develop its own competitive aircraft industry: 1) China should employ institutional innovation, and turn to be market-oriented; 2) China should abandon the traditional pattern of closed-development, and strengthen the interaction and collaboration between aircraft industry and related industries, especially the electronics industry; 3) China should rectify and perfect its spatial development planning of aircraft industry.

Spatial structure and land use control in Extended Metropolitan Region of Zhujiang River Delta,China

The Zhujiang (Pearl) River Delta is one of the most developed Extended Metropolitan Regions (EMR) in China.With the rapid urbanization,the agglomeration of population and industries has emerged,which has led to dramatic changes of spatial structure and land use in this region.With data of high resolution TM remote sensing images and Google Earth maps,this paper identified and analyzed the spatial pattern of the Zhujiang River Delta EMR using Envy and ArcGIS tools.It was found that 1) the industrial land uses were expanding substantially,particularly on the bank sides of the Zhujiang River estuary;2) large-scale housing developments were concentrated in the fringe of metropolitan areas such as those of Guangzhou and Shenzhen;3) a regional transportation network with the spatial pattern of ″1 circle +2 pieces + 3 axes″ had significantly affected the location choice of manufacture enterprises.At the same time,both highly specialized land use and severely mixed land use patterns were identified.As a consequence of the latter,land use efficiency of the whole EMR areas was reduced.Moreover,ecologic and environmental problems were severe.Based on the above analysis,suggestions were given from the viewpoint of spatial safety,land use efficiency,and the reorganization of spatial structure in the Zhujiang River Delta EMR.     

近30年天津滨海新区湿地景观格局遥感监测分析

在GIS和FRAGSTATS软件支持下,结合景观格局数量分析方法,利用1979-2008年间共6期TM遥感影像与非遥感数据,对天津滨海新区近30年的湿地景观空间格局进行了动态分析。结果表明,滨海新区湿地(以人工湿地为主),1979-2004年滨海新区湿地总面积变化不大,但各类型间转换较大,主要是自然湿地转变为人工湿地,沼泽湿地几近消失。2006-2008年,由于城市建设大量滨海滩涂湿地被围填占用,到2009年5月自然海岸线的90%以上被占用。景观破碎度增加,湿地斑块数量从137个增加到704个,同时造成平均斑块面积下降。驱动力分析表明,降雨量减少的同时,年平均气温上升是主要的自然驱动因素。和自然因素相比,人类干扰为主要人文驱动因素,表现在水产养殖为主的农业经济活动、城市建设用地占用和围海造地等方面。目前,滨海新区几乎没有自然湿地生态系统,破碎化和人工化是该区域湿地的主要特征。

Evaluation of role of Home Market Effects in China’s manufacturing industries

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.     

Characterization of air pollution in urban areas of Yangtze River Delta,China

The hallmark of development in the Yangtze River Delta (YRD) of East China has been sprawling urbanization. However, air pollution is a significant problem in these urban areas. In this paper, we investigated and analyzed the air pollution index (API) in four cities (Shanghai, Nanjing, Hangzhou and Ningbo) in the YRD from 2001 to 2012. We attempted to empirically examine the relationship between meteorological factors and air quality in the urban areas of the YRD. According to the monitoring data, the API in Shanghai, Nanjing, Hangzhou slightly declined and that in Ningbo increased over the study period. We analyzed the inter-annual, seasonal, and monthly variations of API, from which we found that the air quality had different temporal changes in the four cities. It was indicated that air quality was poor in winter and spring and best in summer. Furthermore, different weather conditions affected air quality level. The wind direction was considered as an important and influential factor to air pollution, which has an impact on the accumulating or cleaning processes of pollutants. The air quality was influenced by the different wind directions that varied with seasons and cities.     

Regional distribution and sustainable development strategy of mineral resources in China

This paper summarizes the distribution and production layout of the major mineral resources in China,including coal,iron ore,copper and bauxite,from a national perspective.It also identifies the incompatibility between the mineral resources distribution and regional economic development.Significant issues with China’s mineral resource industry cause challenges for the sustainable development of both the mining industry and the national socio-economy.The sustainability of regional mineral resources and the environmental pollution by mining in the western China were also analyzed.Results show that the distribution of China’s mineral resources is misaligned with its regional layout of economic development.China’s mineral resources have been over-exploited,and the mineral resources production in the eastern China is unsustainable.The continuously expanding production of mineral resources in the western China has heavily endangered the ecological environment.We propose strategies to boost the sustainable development of mineral resources,including measures to accelerate economic development and enhance the sustainability of domestic mineral resources.We also offer suggestions for scientifically planning the mineral resource prospecting and exploitation and regional economic layout,as well as for proactively undertaking industry transfer in the eastern China and raising the environmental benchmark requirements for the mineral industry in the central and western China.     

CHANGING FEATURES AND TREND OF LIGHT INDUSTRY DISTRIBUTION IN NORTHEAST CHINA

Modern industry in northeast China started from light industry. From the end of 19th century to 1931 was the phase of initial development of light industry in northeast China. During this period, the development of light industry gave priority to grain processing industry. After occupying northeast China, Japanese vigorously developed heavy industry to meet the needs of munitions and paid more attention to raw materials and semi-finished articles industry for the purpose of the war. Light industry was impeded and developed slowly. After the founding of New China, large-scale economic construction took place in northeast and heavy industry received prior investment and equipment. Northeast region became the first heavy industry base through several five-year plans, the development of light industry made giant strides. The present features of light industry distribution are: difference of light industry distribution, similarity of light industry structure, and imbalance of light industry development. The

Co-benefits of local air pollutants and greenhouse gas reduction achieved by hydropower development in Xizang (Tibet) Autonomous Region,China

Hydropower development in Xizang (Tibet) Autonomous Region plays a vital role in co-control of local air pollutants and greenhouse gas (GHG) in China. According to emission factors of local air pollutants and GHG of coal-fired power industry in different hydropower service regions, we estimate the effect and synergy of local air pollutants and GHG reduction achieved by hydropower development in Tibet, examine the main factors constraining the effect and synergy, using correlation analysis and multiple regression analysis. The results show that: 1) During the period from 2006 to 2012, the effect of local air pollutants and GHG reduction achieved by hydropower development in Tibet decreased as a whole, while the synergy increased first and decreased afterwards. 2) The effect and synergy of local air pollutants and GHG reduction achieved by hydropower development in Tibet vary significantly across different hydropower service regions. The effect based on emission levels of Central China power grid (CCPG) and Northwest China power grid (NCPG) was more significant than that based on emission level of national power grid (NPG) from 2006 to 2012, and the synergy based on emission levels of CCPG and NCPG was also more significant than that based on emission level of NPG from 2010 to 2012. 3) The main factors constraining the effect and synergy based on emission levels of NCPG and CCPG included SO₂ removal rate and NO _x removal rate, the effect and synergy based on emission level of NPG was mainly influenced by net coal consumption rate. 4) Transferring hydropower from Tibet to NCPG and CCPG, and substituting local coal-fired power with hydropower can greatly help to co-control local air pollutants and GHG, transform the emission reduction pattern of the power industry and optimize energy structure.     

SPATIAL STRUCTURE EVOLUTION OF SYSTEM OF RECREATION BUSINESS DISTRICT ——A Case of Suzhou City

The growing attention on urban tourism was very widespread. There are two angles to study urban tourism: supply-side and demand-side. And the supply-side of the tourism remains very important. The RBD (Recreation Business District) is a useful framework to understand the components of urban tourism and how they fit together. The paper begins with a review on the RBD and the spatial structure of tourism in urban areas and then attempts to develop a more general understanding of the spatial structure evolution of RBDs in a tourist-historic city—Suzhou. The spatial structures and functions of the RBDs in Suzhou are examined, based on field observations, interviews with city officials and industry leaders, and a review of available documents. The urban tourism of Suzhou has developed in a range of contexts, that various types of RBDs have emerged as a result of different urban development strategies. The spatial structure has evolved from the past “Single-cored Structure“ to “Double-cored Structure“ at present, and then to “Chain Structure“ in the future. The spatial form and evolution of RBD in Suzhou are closely relative with its urban spatial expansion. Urban area dispersal is the prerequisite of the emergence of the RBD. Planning and constructing the RBD becomes a new impetus to urban growth or renewal. Finally, a number of strategies for planning and developing the RBD in Suzhou are suggested. The different RBDs should adopt different strategies.Intensification can be the possible strategy for the RBDs in the ancient city. Accreting with the urban theme park or engrafting on the Jinji Lake is suggested respectively for the RBD in the Suzhou New District and the Suzhou Indus-trial Park.

我国的经济社会数据主要以各种级别的行政单元为统计对象,这往往会掩盖行政区域的内部差异,当区域内部差异较大时,这些数据就无法真实反映区域的经济社会实际情况。利用地理信息技术与分析方法,本文给出了经济统计数据空间离散模型,分别计算得到了1995、2000、2005年三个年份的我国第一、二、三产业增加值的空间离散数据(公里格网数据),并由此计算得出1995-2000年、2000-2005年两个时段的中国三次产业空间结构变化空间数据。与传统的以行政区为对象的产业结构数据相比,产业结构空间数据能够更好地反映各地的产业结构变化情况,更详细地表达产业结构的空间差异,为区域产业政策的制定以及区域科学发展评价提供依据。     

Relationship between Antarctic sea ice and the climate in summer of China

The variations of sea ice are different in different regions in Antarctica, thus have different impacts on local atmospheric circulation and global climatic system. The relationships between the sea ice in Ross Sea and Weddell Sea regions and the synoptic climate in summer of China are investigated in this paper via diagnostic analysis methods by using global sea ice concentration gridded data covering Jan. 1968 through Dec. 2002 obtained from Hadley Center, combined with Geopotential Height on 500hPa and 100hPa over North Hemisphere and monthly precipitation and air temperatures data covering the corresponding period over 160 meteorological stations in China obtained from CMA （ China Meteorological Administration）. Results disclose that both these two regions are of indicative meanings to the climate in summer of China. The Ross Sea Region is the key sea ice region to the precipitation in Northeast China in summer. More sea ice in this region in September will result in less precipitation in Northeast China in the following June. Weddell Sea Region is the key sea ice region to the air temperature in Northeast China in summer. More sea ice in this region in September will contribute to lower air temperature in Northeast China in the following June.

INDUSTRIAL LINKAGES AND RURAL INDUSTRIALIZATION: A CASE STUDY OF HENAN PROVINCE, CHINA

The fast growth of rural industry in China has generated regional development of large rural areas. What role does industrial linkages play in Chinese rural industrialization? This is a same question as the relation between industrial linkages and regional development which has been discussed for decades and no final conclusion reached. The paper pursues the discussion and focuses on rural areas in China with special reference to Henan Province. On the basis of data from an investigation on nearly 200 industrial enterprises, this study emphasizes that the linkages play a very important role in spreading development of industry in rural areas. It is recommended that the national policies should prompt industrial linkages to upgrade the technological level of rural industry and to integrate rural industry with urban industry.     

面向GTP的三维地质模型空间剖切方法与应用

广义三棱柱（GTP）是近年来提出并被广泛应用于三维地质建模领域的一种较为成熟的空间数据模型,可满足大多数地质钻孔数据的三维地质建模的要求。然而,现有针对GTP模型的三维空间剖切分析方法,仍无法适用于偏斜钻孔数据所建三维地质模型高效多次任意剖切、不能支持较为复杂的地质模型空间分析的问题。本文通过对GTP剖切算法改进研究,提出了采用动态四面体剖分法减小数据冗余;鉴于GTP形态较为复杂,可对剖切后保留多面体进行拓扑关系的重组,解决任意多次剖切问题;将多次“面-体”形式的单剖切运算组合为一次“体-体”形式的复合剖切运算的方法,可高效实现对三维地质模型空间分析。本文着重面向GTP体元的多重任意切剖平面的剖切问题,在分析了GTP体元特征的基础上,弥补了三维地质建模领域中对GTP体元任意、多重剖切方法研究的不足。应用实例表明,上述改进算法可以提高GTP剖切计算速度,并能够快速实现巷道掘进模拟,以及空间开挖模拟等复杂的空间分析功能。
