ANALYSIS OF CAPITAL FLOW WITH GIS——Two Approaches for Reional Investment in China

GIS technology has been mostly concerned with handling physical data and modeling physical environment .However,the requirements of GIS for handling socio-ecnomic information in many cases are different from those concerning phenomena in the physical environment ,Analysis of capital flow among regions requires the transitions both from economic values to physical landscape and from physical surfa ce to econmoic explanation.Rapid growth of Chinese economy comes mainly from investment.There are wto main ways for obtaining high growth of investment ,One is government expenditure which usually invests in regional facility and amenity block ,which is regarded as stimulus for attracting investment.The other is the creation of investing center and corresponding capital source areas ,both of which need the central city with the highest growth rate of investment among regions.This paper presents the cluster areas of both government revenue and total investment ,the potential situation of capital flow between central city Shanghai and its neighbor provinces by using “Classification“ and “Interpolation“ functions of ArcView GIS.     

Regional structure of capital market of foreign direct investment in China’s mainland

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.     

CHALLENGES AND PROBLEMS：CHINA‘S URBAN GOVERNANCE

Chinaˊs urban reforms have brought social progress and development,but a comprehensive national system of social welfare(for example,unemployment insurance,pensions,medical care and public housing)for new migrants from rural areas is lacking.One of the most remarkable changes in Chinese cities in the last decade was a change in so-cial“equality“,with the rise of new poverty both in individual communities and some social groups in urban society.Howev-er,there is little social assistance and public infrastructure for the migrants.Governments or communities or individual should pay attention to the control of new urban poverty and new slums.This paper consider that it is necessary to launch a successful policy,which include mainly:1)accommodating urban growth through low-cost investment projects;2)ur-ban economy depends heavily on successful macroeconomic policy;3)to broaden the three channels linking adjustment to the incidence of urban poverty;4)to restructure urban economic based on the high or new technology;5)to coordi-nate relationship between urban economic growth and environment management for sustainable development of Beijingˊs metropolitan fringe.     

A PATH-DEPENDENT MODEL OF INVESTMENT AND EMPLOYMENT FLOW IN A LARGE ECONOMY IN A PROCESS OF INTEGRATION

This paper meant to analyze the spatial evolution of a large country in its process of integration with the world economy in general, and, to look into the possible effect of China‘s accession into WTO on the future development of its spatial economy in particular. Through an approach of increasing returns, external economy, product differentiation and path-dependence, with foreign trade costs incurred by different regions within the large country discriminated, a model of investment and employment flow is developed as a simulation of a large country‘s process of integration with the world economy. The modeling indicates that in the process of integration, as there exist differences in foreign trade costs among different regions within the large country, either the spatial economy of the country deviates from its symmetric structure in autarky and falls into a core-periphery relationship, or the effect of industrial agglomeration is reinforced, amplified and locked in, if the agglomeration had been started. The economic gap on either the aggregate or structural basis between different regions within the large country will increase rapidly as the integration proceeds.     

The link between interannual variation of the South China Sea summer monsoon onset and summer precipitation in Shandong Province

Relationship between the onset date of South China Sea (SCS) summer monsoon and the summer rainfall in Shandong Province was examined by comprehensive analysis to establish a conceptual model of the link. If the summer monsoon occurs earlier, the 500 hPa level would induce the teleconnection of Eurasian pattern in the summer (June-August), which indicates that the western Pacific subtropical high is displaced northward further than usual, the Siberian high is intensified and the Okhotsk low is deepened. Under such circumstance, Shandong, located in the west side of the subtropical high and in front of the mid-Siberia high, would be expected to have a wet summer because it is quite possible for cold and warm air to meet and interact with each other in Shandong. Statistical analysis revealed that the 500 hPa anomalies over Korea and Japan were sensitive to the SCS monsoon onset date and very important to precipitation in Shandong, and that the convective activities over the deep water basin in the SCS in 24-26 pentads significantly influenced the position of the ridge line of the western Pacific subtropical high. These findings yielded better understanding of the causative mechanisms involved in the precipitation generation, so that the knowledge gained can possibly be applied for long-lead forecast.     

Regional disparity and convergence of China’s inbound tourism economy

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.     

Hong kong direct investment in china’s mainland: A spatial study with special reference to the locational behaviour of investors

The study shows that the regional differentiation of Hong Kong direct investment (HKDI) in China was enlarged in the 1980s and has been reducing since 1991. The concentration of HKDI in the southern China and the coast has been replaced by the trend of moving northwards and inlandwards after 1989. But in terms of manufacturing sectors this trend has not clearly appeared until now. Those changing patterns are clearly related to the behaviour of Hong Kong industrial investors. The survey results suggest that “enjoying lower production cost” is the most important motive for their investment in China. In consequence, “close to Hong Kong”, “cheaper labour” and “favourable policy” are major factors for determining the investment locations. This behaviour, together with the lack of comparison study in location selection among most investors, explains that Guangdong absorbed most Hong Kong investment in the 1980s. As the production costs have been increasing in Guangdong, some companies have started to invest in non-Guangdong locations since the end of the 1980s. From the mental map of Hong Kong investors, however, only some of the non-Guangdong locations are practically attractive.

Spatial distribution of integrated impact index of mega-event—A case study of Expo ′99 Kunming

Taking the affinity between events and media as a conceptualization base, a total of 1032 related news reports of Expo ＇99 Kunming, gathered from the internet data bank of China INFOBANK from 1992 to 2003, are used as data sources. After classifying them with a communication research method--the content analysis, a data bank for SPSS is set up, and a mathematic model called the Integrated Impact Index of Expo ＇99 Kunming is constituted. With the model, the spatial distribution of the total integrated impacts of Expo ＇99 Kunming on the regions or cities with different regional scales is analysed quantitatively. The conclusions are： 1） the Expo ＇99 Kunming made obvious inte- grated impacts on the regions or cities of every scale, especially in the venue city and the region--Kunming City and Yunnan Province; 2） it had corresponding impacts on other provinces; 3） the spatial distribution of Integrated Impact Index had a disaggregation with both plane extension and spotted decentralization; and 4） there was a distance decay law in all three scales of regions （Kunming City, Yunnan Province and the whole China）, which incarnated the spatial extension law of the integrated impact of a special mega-event.

Determinants of public goods investment in rural communities in mountainous areas of Sichuan Province,China

This study aims to investigate two important issues： what are the determinants of public goods investment and what is the government＇s investment behavior in mountainous areas. The impacts of natural conditions, target, and demand elements on public goods investment are analyzed with statistical method, and the determinants of public goods investment in the areas are obtained by using population-weighted and stepwise regression models with Eviews6.0 software with survey data in 2008 and calculated data based on GIS of 20 typical villages in mountainous regions in Sichuan, China. The results showed： （1） natural conditions are the important determinants of public investment. Mountainous villages with steep slope have relatively high levels of investment; （2） concentration of population and the educational levels of the village leaders also have important impacts on public goods investment; （3） the government is more concerned with public investment resources particularly in areas characterized by fragile ecological environment and poor agricultural output. These results suggest that the current investment strategy helps to reduce disparities in regional development.     

Comparative Analysis of Nutrient Composition of Caulerpa lentillifera from Different Regions

This study investigated the difference of nutrient composition in Caulerpa lentillifera collected from different regions.The nutrient compositions of C.lentillifera from China's Hainan and Shandong provinces were determined and compared with those from Semporna(Malaysia),Sabah(Malaysia),Petchburi(Thailand),and two other species of seaweeds(Malaysia).The results showed that the polysaccharide and protein contents of C.lentillifera from Hainan(44.82%±0.98%and 12.5%±0.70%),Shandong(43.22%±1.42%and 14.7%±0.72%),Petchburi(59.27%±2.31%and 12.49%±0.30%),and Sabah(44.02%±2.01%and 19.38%±1.48%)were higher than those of Eucheuma cottonii(26.49%±3.01%and 9.76%±1.33%)and Sargassum polycystum(33.49%±1.70%and 5.40%±0.07%),respectively.The polyunsaturated fatty acid contents in C.lentillifera from Hainan(29.98%)and Shandong(22.11%)were higher than that in Semporna(16.76%±0.27%),Sabah(9.49%),and S.polycystum(20.34%±0.43%),but lower than that in E.cottonii(51.55%±0.57%).In Caulerpa lentillifera of Hainan and Shandong provinces,the essential amino acid(EAA)/total amino acid(TAA)ratios were 35.22%and 38.78%,respectively;and the EAA/ETAA ratios were 54.36%and 63.35%,respectively.The EAA composition of C.lentillifera was close to the ideal model of Food and Agriculture Organization/World Health Organization.C.lentillifera was rich in mineral elements,including calcium((3315.85±127.55)mg(100 g)^-1 and(3728.35±92.38)mg(100 g)^-1),magnesium((6715.74±82.58)mg(100 g)^-1 and(8128.59±242.72)mg(100 g)^-1),and trace elements,including iron((510.65±5.47)mg(100 g)^-1 and(1972.97±183.35)mg(100 g)^-1),selenium((1.04±0.08)mg(100 g)^-1 and(0.83±0.15)mg(100 g)^-1),and zinc((33.90±0.13)mg(100 g)^-1 and(11.75±2.05)mg(100 g)^-1).These results showed that C.lentillifera was more nutritious than S.polycystum or E.cottonii in terms of polysaccharide,protein,and fatty acid contents.Furthermore,both C.lentillifera species collected from Hainan and Shandong provinces show more basic nutrients.Therefore,C.lentillifera has important development and application prospects.     

A PRELIMINARY APPROACH TO THE REGIONALIZATION OF THE MARINE COMPREHENSIVE ECONOMIC REGION IN LIAONING PROVINCE

China is a country with a vast marine territory whose area covers one third of the total land territory area. With the exploitation of marine resources and the development of marine economy, marine economic regions have been formed gradually. We shouldn’t ignore them when we divide economic regions throughout the whole nation, especially in our country. In this paper, we’ Il expand division principles, practice and methods of marine comprehensive economic region. Liaoning Province, facing the Yellow Sea and the Bohai sea, is not only a part of Round-the-Bohai Sea Economic Region, but a part of national marine econemic region. Through evaluating marine resources of Liaoning, and analyzing development of marine economy, composition of marine industries and distributional characteristic of marine economy, Liaoning marine region is divided into Bohai Sea marine economic region and Yellow Sea marine economic region based on differences of marine economy. Thereby we go further into the formation of regional marine economic region and distributional mechanism of regional marine economy.

干旱胁迫下植物抗逆性大尺度遥感监测方法

目前干旱与植被关系的研究主要集中于气候因子与植被时空变化的相关性分析以及植被对气候变化的响应,能够适用于大尺度的植物抗逆性监测方法还较为欠缺。本文基于归一化植被指数（NDVI）、总初级生产力（GPP）、修正花青素含量指数（mACI）、短波红外水分胁迫指数（SIWSI）监测干旱胁迫下的植被变化,综合考虑植物抗逆过程,建立滞后时间、抗逆时差、响应程度与恢复能力4个植物抗逆性监测指标,构建了一种能够适用于大尺度的植物抗逆性综合监测方法。利用各省份作物抗逆性综合评分与绝收比例进行相关性分析,两者呈显著负相关。利用该方法对干旱胁迫下我国不同类型植被的抗逆性进行评估,结果表明：① 从全国整体水平来看,不同季节植物抗逆性差异较大,其中夏季植物抗逆性最弱,冬季最强。我国植物抗逆性空间异质性显著,春季植物抗逆性综合评分低于70分的区域主要位于山西、陕西北部,综合评分高于90分的区域主要集中在内蒙古东北部以及云南的南部地区; ② 不同类型植被的抗逆性有明显差异,夏季落叶针叶林抗逆性最强,类内差异最小,春秋两季草地抗逆性最强但抗逆性类内差异最大。本文提出的植物抗逆性综合监测方法有助于探索干旱胁迫下植物抗逆性规律,对帮助降低灾害风险具有借鉴意义。     

DISTRIBUTIONS OF CHEMICAL ELEMENTS WITH RELATION TO MAJOR WATER CIRCULATIONS IN THE CENTRAL AND NORTHERN PARTS OF THE TAIWAN STRAIT

Data obtained from a comprehensive multidisciplinary oceanographic survey in the central and northern parts of the Taiwan Strait, 24°20′-26°00′N, 118°45°-121°00′E by the Fujian Institute of Oceanology during the period May, 1983 through May, 1984, showed that the distributions of dissolved oxygen (DO), nitrate, dissolved inorganic phosphate and silicate concentrations here had obvious areal and seasonal characteristics that were mainly influenced by the seasonal circulation ofthree major water systems in the Taiwan Strait-- the Taiwan Strait Warm Water (TSWW), theZhejiang-Fujian Coastal Water (ZFCW), and the Northeastern Strait Warm Water (NESWW).     

Black carbon and polycyclic aromatic hydrocarbons (PAHs) in surface sediments of China’s marginal seas

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 ...     

The present situation, types and changes of China’s environment

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.

SPATIAL ANALYSIS OF SOIL EROSION AND NON-POINT SOURCE POLLUTION BASED ON GIS IN ERLONG LAKE WATERSHED, JILIN PROVINCE

Data collection, factor composition, nappe analysis and integrative simulation of natural geographical factors in Erlong Lake watershed have been carried out based on GIS. The risk areas where non-point source pollution may occur were compartmentalized and assessed, and the total soil erosion and the runoffs of N and P with rainfall in this valley were worked out by experiment and GIS mapping. The study indicated that the main type of soil erosion was moderate (erosion modulus is 1000–2500t/(km²·a)) at present, and the intense erosion areas are located in dry land with variable slope east of the lake and the middle-south parts of steep slope mountainous region (erosion modulus is more than 5000t/(km²·a)). Though the area is small, it should be paid attention to. The trend of non-point source pollution (NSP) of nitrogen and phosphorus loss was corresponded with the soil erosion. Spatial distribution and the reasons of the distribution difference have been presented and it was emphasized that the human activities among the influence factors was the most important. It surely offers a scientific basis to control and prevent non-point source pollution in the watershed.

Eco-spatial Structure of Urban Agglomeration

In terms of ecological theory, this paper makes a comprehensive analysis of the mutualism and co- evolutionary mechanism between the eco-spatial structure and socio-economic development of the urban agglomeration, and maps out optimized modes of the eco-spatial structure of the urban agglomeration. The analysis is a case study of the urban agglomeration on different levels of global, national, provincial and local scales, on the basis of those conclusions are drawn: 1) Within the scope of the urban agglomeration, the cities should be reasonably sized and appropriately densified; the spatial combination of the urban agglomeration ought to be orderly, and its eco-spatial structure ought to be optimized and efficient; the relationship between the economic society and eco-spatial environment ought to be that of mutual benefit and co-evolution. 2) “The mode of corridor group network” is a certain trend evoked from the spatial structure of urban agglomeration. 3) The eco-spatial structure of urban agglomeration under “the mode of corridor group network” can further increase the environmental capacity of urban agglomeration, and is in favor of the harmonious relationship between man and nature.
