GIS-BASED ANALYSIS OF URBAN LAND-USE CHANGES—A Case Study of Haizhu District of Guangzhou City, China

This paper describes a GIS-based spatial analysis method that combines qualitative analysis and quantita-tive analysis to characterize land-use patterns and predict the trend of future land-use changes in Halzhu District ofGuangzhou City, China. Spatial technique is introduced to manage land-use data and derive information of land-usechanges. Through the case study for the selected area, it is demonstrated that the method and technique introduced in thepaper can be effectively utilized for the analysis of urban land-use changes. Based upon this analysis, the paper also pro-vides discussions and recommendation on urban land-use planning, urban planning and land management. Both land-usemaps of Haizhu District of Guangzhou in 1995 and 1997 and the remote sensing images of 1999 are utilized in the cur-rent research. It is convenient to get various statistic data and to combine attribute data with spatial data so as to analyzeland-use changes in a geographic context, which is especially suitable for the need of urban construction department, ur-ban management department and urban planning department.     

ON FRACTAL MECHANISM OF COASTLINE —A Case Study of China

MANDELBROT enunciated the uncertainty of the length of a coastline in his paper“How long is the coast-line of Britain?“ published in “Science“in 1967.The fractal concept was presented for the first time in that paper and has been applied to many fields ever since.According to the fractal theory and conditions of fractal research of coastline,the controls of faults and biologic function on the fractal character of coastline are preliminarily discussed on the basis of GIS in this paper.Finally,some significant conclusions are drawn:1)the faults control the basic trends of coastlines of two study areas;2)the fractal dimension of coastline of Taiwan is smaller than that of Changle-Lufent,because the faults of Taiwan more intensely control the trend and fractal dimension of the coastline;3)the larger the fractal dimension of the faults or the major faults ,the more the controlling effect of them on the trend and fractal dimension of coastline;4)the larger fractal dimension of the coastline of Changle-Lufeng indicates that the biologic function intensely shapes the coastline .In a word ,the controls of faults and biologic function on the fractal character of coastline are discussed with a case study of China in this paper,it can be seen that faults and biologic function both have influence over the trend and fractal dimension of coastline,the fractal mechanism of coastline of two study areas may be so.     

STRATEGIC ENVIRONMENT ASSESSMENT ON LAND—USE PLANNING—A Case Study of Changchun Economic and Technological Zone

The study centers on the necessity,the workflow and the synthetically integrated methods (Principal Compo-nent Analysis(PCA),Andytical Hierarchy Process(AHP) and Fuzzy Comprerhensive Evaluation(FCE)of strategic environ-ment assessment(SEA)on land-use planning.The whole article includes three main parts:firstly,some attribute database,graphic-base and the spatial transform matrix,which reflect the change of regional land-use pattern,can be ob-tained by GIS technique;secondly,adopting fitting method of trend-suface analysis will convert environment monitoring data from scattered spots to regular control spots,based on which we can perform regional environment impact assess-ment;finally,Changchun Economic and Technological Developmen Zone is chosen as a case study on land-use planning.Through those efforts the results may be obtained as follows:1)according to transform matrix,the possibility of transforma-tion from one land-use to another can be obtained after the planning is carried out;2)environment ruality would change as a result of the change of land-use pattern;3)the SEA on land-use plan is an effective tool to make land-use pattern more reasonable.

STUDY ON SPATIAL LANDSCAPE PATTERN OF YANTAI CITY BASED ON RS AND GIS

Influenced by artificial factors, landscape pattern of Yantai City, Shandong Province changes continu-ously. Revealing its landscape pattern and its changing process has a practical significance for the urban development and layout. Zhifu District, Development Zone, Laishan District and Fushan District in Yantai City were selected to study the landscape pattern. Remote sensing technology was used to obtain landscape information of different peri-ods. Under the support of Geographic Information System (GIS), the spatial landscape pattern of Yantai City was an-alyzed and simulated by using various special quantitative analysis models. The analysis shows that built-up area lies in the center of Yantai City, the outside is vegetable land. irrigated land, dry land, garden land and woodland.

Spatio-temporal patterns of intra-urban land use change in Beijing, China between 1984 and 2008

Urban internal structure is essential information for urban geography researchers and urban planners or managers. This research aims to examine the spatial structure changes of internal urban land use based on the interpreted datasets of 1984 and 2008. Spatio-temporal patterns of internal land use conversion and urban expansion are analyzed, and then dominant driving factors (e.g., social economy, population growth and urban planning) were identified. The results indicate that Beijing′s intra-urban layout has experienced tremendous adjustment from compact to disperse configure, otherwise its function objects have shifted from the major economic and industrial development before the 1990s to the combination with cultural, high-technological and inhabitable city at present. The dominant urban land use transformations include the relocation of industrial lands from core districts to suburban or other provinces, and the accelerating expansion of residential areas and green spaces for supplying the demand of housing and ecological protection. Although Beijing′s urban planning has experienced three major adjustments and improvement since the 1980s, its optimization of urban internal patterns still remains a challenge.

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.

Measurement and spatial distribution of urban agglomeration industrial compactness in China

Urban agglomeration （UA） compactness means spatial concentration degree of physical entities, such as cities （towns）, industries, resources, funds, traffic and technologies, whose concentration is formed according to specified economic and technologic association in the process of UA formation and development. The UA industrial compactness means the concentration degree of industry and industry clusters with reference to the industrial, technological and economic relations among the cities in the UA in the process of rational industrial division and with the extension of industrial chain. After analyzing the researches on compactness, this paper finds that the relevant measurement coefficient and methods reflecting industrial geographical concentration fail to link industries spatial concentration with urban spatial concentration. Taking 23 UAs as samples and classifying them by development degree, this paper probes into UA compactness and spatial distribution characteristics from the perspective of industry by adopting UA index systems of industry and measurement models. The research finds out： 1） there is obvious positive correlation between UA industrial compactness and UA development degree; 2） the spatial distribution difference of UA industrial compactness is relatively great; and 3） UA industrial compactness shows a gradually decreasing tendency from the eastern part, the middle part to the western part of China. From the research thoughts and approaches, this article suggests that studies on the UA integrated compactness measurement should be enhanced from a multidimensional per- spective involving space, traffic, population density and so on.
