摘要

针对城市河流特点

建立了城市河流脆弱性评价体系

为城市河流的利用和保护提供参考。以浐灞河流域为研究对象

选取适当的评价指标

采用熵权赋值法确定权重

并应用模糊综合评价法计算分析了浐灞河的脆弱程度。结果表明

马渡王、常家湾以下地区脆弱程度最大

其他地区脆弱度较好。建立的城市河流脆弱性评价体系能够系统地反映城市河流的脆弱性

在水资源脆弱性的研究方面有所发展。模糊综合评价法方法简洁

能够比较客观地反映河流现有的以及潜在的脆弱性

可应用于城市河流脆弱性评价中。

Abstract

According to the characteristics of urban rivers

a vulnerability assessment system for urban rivers are established so as to provide a reference for the use and protection of urban rivers.By taking Chanba River as the research object

the vulnerability of the river is analyzed by choosing several appropriate evaluation indexes

using entropy method to determine the weights

and applying fuzzy comprehensive evaluation.Results show that the area below Maduwang and Changjiawan has the highest vulnerability

whereas other places have low vulnerability.The established system can systematically reflect the vulnerability of urban rivers and make some develpment in the research on the vulnerability of water resources.The method of fuzzy comprehensive evaluation is simple and can objectively reflect the current and potential vulnerabilities of rivers.Therefore

the method can be used for vulnerability assessment of urban rivers.
