THE CONSTRUCTION OF URBAN- REGION SPATIAL DEVELOPMENT PATTERN BASED ON GEOGRAPHICAL POLYLINE METHOD
以江苏省为例，提出地理折线法理论并应用于区域发展，通过AHP计算13市竞争力绘制折线，结合GIS分析提出趋势与连通策略，构建城市区域发展格局。
Taking Jiangsu province for example,the paper puts forward the theory and the application in regional development of geographical polyline method.According to the value of urban competitiveness of 13 cities of Jiangsu Province calculating by AHP and inverse sequential analysis,the author draws the geographical polyline.After carrying out trend analysis,connectivity analysis and local analysis with the help of GIS,the author puts forward the trend strategy and the connectivity strategy of Jiangsu province.Finally,the author gives five main development lines and two supporting development lines through rationally connecting convex points,concave points and flat points,andthen constructs urban-region development pattern of Jiangsu province.
