摘要
以网格为评价单元,对生态重要性、灾害易损性、水环境容量、可建设用地比例、交通可达性、人口与经济集聚度6项指标进行了综合评价;利用Arc GIS的空间分析模块进行距离分析、密度分析和坡度分析;利用Delphi法进行原始数据标准化处理,计算适宜性指数并分级,将新沂市空间开发适宜性等级划分为低适宜性、较低适宜性、中适宜性、较高适宜性和高适宜性5种类型,从而进行更为合理、更具计划性的规划,以促进区域协调和可持续发展。
In this paper, taking grid as the evaluation unit, we synthetic analyzed six evaluation indicators including ecological importance, the vulnerability of disaster, water environmental capacity, the proportion of construction land, traffic accessibility, population and economic agglomeration degree. And then, we used the spatial analysis model of Arc GIS to analyze the distance, density and surface(slope). Finally, we used Delphi method to standardize the original data, calculated and classified the suitability indexes. The result shows that Xinyi City is divided into five types, such as high suitability, moderate suitability, middle suitability, critical suitability and non-suitability. On basis of this, some more reasonable and more planned arrangements are made, to promote regional coordination and sustainable development.
