摘　　要：针对生态环境供水的特点,采用机会成本法分析生态环境供水经济效益并计算其影子价格;并根据河流下游各用水部门供水保证程度,提出借助农业灌溉经济效益计算生态环境供水经济效益的方法.最后以某河口地区为例,计算了该地区生态环境供水的经济效益.In consideration of the characteristics of ecological environment water supply, the opportunity cost method is adopted to calculate its shadow price, and a method is put forward for calculating the economic benefit of ecological environment water supply on the basis of the economic benefit from agricultural irrigation based on the level of guarantee of water supply to water consumption departments on the lower reaches of rivers. As a case study, the economic benefit of ecological environment water supply is calculated for an estuarine region.

关 键 词：机会成本 影子价格 线性规划 生态环境 灌溉效益
