摘要
区域城镇发展用地评价是区域经济开发的先行步骤。作者利用地理信息系统的技术,建立地形评价模型、基础设施辐射范围扩散模型、分区多幅图覆盖分析模型等一整套模型,使评价工作较以往更为科学、系统,且省时省力。本文研究了海南省城镇发展用地条件。
Regional landuse evalution for the development of cities and towns is an important prerequisite of regional economic development. In this paper, with the help of Geographic Information System, the authors set up a new evalution system, it is formed by a series of models, such as Landform Evalution Model, Diffuse Models, Multi-factor Overlay Model, etc. Among these models, the Multi-factor Overlay Model is the most important one.Its action is to combine some relative evalution maps with several new maps. These new maps combine the information from the previous maps selectively, with these new evalution maps and some other material, the evalution work can be more efficient and accurate,Ilainan province is the largest Special Economic Zone in China. It is also the only large tropical island in China. .So it is very important to use its land and other resources rationally and economically .The authors apply this evalution system on regional landuse evalution for the development of cities and towns in Hainan province. The result is satisfactory and we may divide the whole island into five different parts. ], NorthUrban-Industrial Zone. 2. Green Zone, taking agriculture and other tropical crops as dominant factor. 3. Reserved Zone for Urban-Industry, 4, Ecologic protection Zone. 5. Seaside Tourist Zone
