摘　　要：为了分析不同闸坝调度方式下污染河流水质时空变化规律,探索闸坝调度对污染河流水质水量的作用机理,本文在对槐店闸多次实地调查和水质监测的基础上,设计了一套不同闸坝调度影响河流水质的实验方案,并进行了现场实验,研究了槐店闸现状调度、闸门开度减小、闸门开度增大三种调度方式下的水体和底泥污染物变化规律。结果表明:闸坝对污染河流水质的影响作用呈现出复杂的非线性关系;闸坝调度对河流水质有一定影响,其影响大小与闸门开度有关。本文的研究工作为构建闸坝作用下河流水质模型、分析闸坝作用规律、实施闸坝科学调度奠定了实验基础。The purpose of the study is to analyze the spatial and temporal variation rule of polluted river water quality under various operation conditions of gate,and explore the mechanism of the operation to water quality and quantity.According to the several survey and water quality monitor of Huaidian gate,a series of experimental programs on the influence of river water quality by gate operation were designed and the field experimentats were carried on to study the variation rule of pollution in the water and sediment under three schedule rules of gates＇ opening as normal,decrease and increase.The results showed that the influence of gate operation on polluted river water quality is complex and nonlinear.The gate operation has certain impacts on river water quality and the extent is related with the gates＇ opening.The research established the theoretical base for the water quality model construction,analysis on action rule and scientific operation.
