水库是重要的水源地及保护区，在区域水资源环境安全中具有不可替代的地位。现利用辽宁省6座水库监测数据，根据韦伯-费希纳定律，选取 COD 、TP 、TN 和 NH3-N 4个与水库水环境关系密切的水质评价指标，通过确定水环境综合影响指数 ki值与地表水环境综合预警等级之间的关系，建立水环境预警模型。结果表明：ki值与地表水环境综合预警等级呈幂函数关系，截止2009年6座水库均未达到国家 I 类水质标准，汤河水库下达河监测点综合预警等级为重警，建议加强流域水库水环境的监控和采取更严格的管理措施。

As an important water source and nature reserve ,the reservoir has an irreplaceable role to security of regional water resources .The monitoring date of COD ,TP ,TN and NH3-N from 6 reservoirs in Liaoning prov-idence were collected ,which were closely related to water environment quality .According to Weber- Fechner law ,the relationship between water environmental impacts index (ki )and surface water environment quality forewarning level ,and the forewarning model of water environment quality were studied .The results showed that the relationship between ki value and surface water environment quality forewarning level was power func -tion .At the end of 2009 ,the water qualities of 6 reservoirs were all lower than the level of national water quali-ty standard I .The forewarning level of Xiadahe monitor site of Tanghe reserve was serious level ,which indica-ted that water quality monitoring needed improve and a stricter management of the reserve should be carried out .
