摘要
从水资源脆弱性产生的内部因素和外部因素两方面考虑建立水资源脆弱性评价指标体系。利用结构熵权法,定性分析与定量分析相结合确定指标权重,结合模糊综合评价法评价了黄河上游水资源脆弱性。结果表明:从河源到河口镇水资源内部脆弱性逐渐明显,由于各省区社会经济及供用水不同,水资源脆弱性综合评价表现为一定的差异性。
The water resources vulnerability system reflects the inernal and exteral factors of the vulnerability of water resources.Structural entropy method,which combines qualitative analysis with quantitiative analysis,was used to determine the index weight,and then was combined with fuzzy comprehensive evaluation method to assess the vulnerability of water resources in the upper reaches of the Yellow River.The results showed that the internal water resources vulnerability gradually becomes serious from Heyuan to Hekou Town;because of the differences of socio-economic and water supplies among provinces,the comprehensive evaluation results of water resources vulnerability were different.
