水资源开发利用状况综合评价方法研究

A Study of Comprehensive Evaluation Methods on the Development of Water Resources

在简单评述主成分分析法、灰色关联分析法、层次分析法和物元分析法等综合评价方法的基础上,将这些方法应用于对我国重要粮食基地松辽流域的水资源利用现状的综合分析,不仅对松辽流域的水资源利用及粮食生产安全现状给出了综合评判,还根据评判结果,对比分析上述方法的适用范围和限制条件等,指出了相应的改进方向。

This paper simply makes a comment on several comprehensive evaluation methods including the principal component analysis,the gray correlation analysis method,the analytic hierarchy process（AHP） and the matter-element analysis.Then based on these methods,a comprehensive analysis is made of the status quo of Songhuajiang River and Liaohe River basins,which are important grain bases in China.At last,a comprehensive evaluation is made of the present water resources situation of the Songhuajiang River and Liaohe River basins.And based on the results,the scope and constraints of these methods are analyzed and corresponding improvements are pointed out.
