采用单因子评价法对生态水网供水水质和水网区地下水质现状评价，找出主要污染物并计算超标倍数，对水库水体增加综合污染指数法和富营养化程度评价。依据以水质参数浓度及其采样时间为研究对象的回归方法和监测值动态变化曲线法，分析地表水质和地下水质主要指标的变化趋势，进而分析生态水网对东部平原水质的影响。
採用單因子評價法對生態水網供水水質和水網區地下水質現狀評價，找齣主要汙染物併計算超標倍數，對水庫水體增加綜閤汙染指數法和富營養化程度評價。依據以水質參數濃度及其採樣時間為研究對象的迴歸方法和鑑測值動態變化麯線法，分析地錶水質和地下水質主要指標的變化趨勢，進而分析生態水網對東部平原水質的影響。

The water qua lity status based on single-factor evaluation of water supplies and groundwater in the ecological water network region, find out the main pollutants and calculation the times of exceed standard, increase the evaluation method of the comprehensive pollution index and the eutrophication degree for reservoir water body.According to regression method of water quality parameterand and sampling time and dynamical change curve method of the monitoring value,analy-ses the variation trend of the main indicators of surface water and groundwater and analyses the water quality influence of ecological water network in the eastern plain.
