摘　　要：依据漳河水库灌区水资源现状,采用AHP方法,建立了水资源脆弱性评价指标体系和水资源脆弱度评价阈值,分析了灌区自然脆弱性、人为脆弱性和承载脆弱性等敏感指标,并用2005年实际资料对灌区脆弱性水平进行了评价.结果表明:水资源脆弱性综合评价阈值G=3.05,处于中等脆弱态势;自然脆弱性G1=1.41,处于较强脆弱态势;人为脆弱性G2=3.94,处于不脆弱态势;承载脆弱性G3=3.00,处于中等脆弱态势,与实际情况基本吻合.AHP method was used to build the index system and threshold of water resources vulnerability evaluation according in the current situations of water resources in the Zhanghe Irrigation District,Hubei Province.The sensitive indexes such as natural vulnerability,the human activity vulnerability,and the carrying capacity vulnerability were analyzed,and vulnerability level of the district was evaluated using the actual data of the district in 2005.The conclusions were drawn：the comprehensive evaluation threshold of water resources vulnerability of the district was G=3.05,at the middle level;the natural vulnerability was G1=1.41,at the high level;the human activity vulnerability was G2=3.94,at the non-vulnerability level;and the carrying capacity vulnerability was G3=3.0,at the middle level.The results were almost consistent with actual conditions of the irrigation district.
