| 摘 要： | 以湖南农业生态水资源库为研究对象,分析了其脆弱性成因和主要表现.从脆弱性成因角度构建了包含10个具体指标的湖南生态水资源库脆弱性评价指标体系,运用模糊物元评价模型对85个县级评价单元的农业生态水资源库脆弱度进行综合评判.结果表明:全省农业生态水资源库脆弱性等级以中等脆弱为主,其中,微脆弱等级11个,占总评价单元的12.9%;中等脆弱等级74个,占总评价单元的87.1%.脆弱度空间分布存在"西部大于东部,南部大于北部"的总体分布态势.其中,以湘西北、湘西南和湘南所构成的外部环形地带和以长沙、衡邵盆地为中心的中东部地带为全省两个比较明显的高脆弱区(带).

| Abstract: | On the basis of the cause of vulnerability,an evaluation index system on the vulnerability of agricultural water resource bank,including 10 concrete indices,is constructed for Hunan province.The ten indices include precipitation,surface water subsystem,soil water subsystem,vegetable water subsystem and economic subsystem,and then the evaluation index system of vulnerability of agricultural ecological water resource bank in Hunan province is established using analytic hierarchy process(AHP).The vulnerability... |
