以南水北调中线水源区湖北省部分为例,采用＂压力—状态—响应＂模型,选取14个评价指标,建立了水源区农用土地生态安全评价指标体系.利用均方差赋权法确定各指标的权重,以县域为评价单元,计算了水源区7县市的农用土地生态安全指数.研究结果显示,2000～2009年研究区域农用土地生态安全状况呈逐渐好转的趋势,但是各县市在时间与空间上存在着差异.

Taking the water source area of the middle line project for transferring water from south to north in Hubei province as a case,and using the ＂pressure-state-response＂ model,the author selects the 14 evaluation indicators and establishes an ecological security evaluation index system of the agricultural land in the water source area.Using Mean-Squared Deviation Weight Method to determine the weight of each index,and taking county territory as unit,the author calculates the ecological security index of agricultural land of 7 counties in the water source area.The results showed that in 2000~2009,agricultural land ecological security situation of agricultural land in the study area was gradually improving trend,but the counties in time and space are differences.
