基于GIS的城市土地可持续利用评价系统的建立

The Establishment of the Urban Land Sustainable Utilization Evaluation System Based on GIS

采用土地评价方法(层次分析法),选取了14个与土地可持续利用相关的指标,并用VB确定各权重值,结合GIS软件MAPINFO建立了土地可持续利用评价系统,从资源环境、经济和社会可接受性三方面计算了土地可持续利用能力,得出评价结果,提出了研究区土地可持续利用的相应问题以及实现土地可持续利用的对策。

By using the land evaluation method （analytic hierarchy process）, this paper chooses 14 indexes related to sustainable utilization of land resource, determines each weighted value with VB, sets up the land sustainable utilization evaluation system connecting with the GIS software MAPII^F0, and calculates the sustainable utilization capability of the land from three aspects of the resource environment, economic acceptability and social acceptability, gets the evaluation results, and puts forward some corresponding problems in research on the land sustainable utilization and some countermeasures for realizing the land sustainable utilization.
