运用模糊综合评价法及层次分析法对辽宁省浑河大伙房水库上游北杂木、古楼及台沟断面丰、枯水期的水质 进行评价, 同时将水质评价结果( 水质模糊综合评价指数) 与对应上游来水量进行相关性分析, 建立来水量与水质模 糊综合评价指数的非线性回归模型, 并利用该模型进行水质预测。结果表明: 非线性回归模型具有较高的拟合效 果, 应用该模型可以对上游各来水断面的水质类别进行预测。

Water quality in the upst ream o f Dahuofang Reservo ir of the H unhe River w as evaluated in three detecting sections ( Beizamu, Gulou, and Taigou) using the fuzzy comprehensive evaluation method and ana lyt ic hier archy pro cess ( AH P) . T he co rr elation analysis between w ater qualit y ev aluatio n results ( w ater quality fuzzy comprehensiv e evaluat ion index ) and cor re2 sponding upstream inflow was prefo rmed. A no nlinear reg ression mo del o f the upstream w ater inflow and water quality fuzzy compr ehensiv e ev aluatio n index w as developed to pr edict w ater quality . The r esults show ed that the no nlinear reg ressio n model has hig h f itting accuracy and it can pr edict t he w ater quality cat eg or ies of each upstream inflow section.
