我国环境生态形势研究的一种方法

An approach to the Eco environmental Situation in China

在分析国内外环境生态形势研究现状的基础上 ,结合我国的环境生态形势特征 ,综合自然、社会、经济因素 ,构建了评价我国环境生态形势的指标体系 ,建立各指标计算的数学模型 ,在地理信息系统和数据库管理系统支持下以全国县域为单元进行多因素综合性定量研究 ,采用指标权重的地域计算方法来反映区域差异 ,得出了全国各县的环境生态形势指标值 ,并绘制出我国环境生态形势图。

Based on the latest research of present Eco environmental Situation at home and abroad and analysis of the characteristics of Environmental Situation in China with the principle of index selection, a set of indices on the Eco environmental Situation in China has been identified. Then 14 county unit databases are set up, including two types: 2 spatial databases and 12 attribute databases. And the mathematical models for each index has been developed. With the powerful systematic analytical tool, GIS, and database management system, this paper classifies each index into five degrees and integrates them into a map according to their respective rights by county unit, which is the distribution of the Eco environmental Situation in China. Finally this paper analyses the distribution of Eco environmental Situation in China, draws compellent conclusions on this methods and discusses some details. Some items that need to be improved afterwards are put forward.
