摘要
为探索水资源调度对太湖上游湖西地区河网水质改善的影响,开展水资源调度期间的水量水质同步监测,分析区域水流的流动特性及水量分配特点,以及调度期内水体流动下区域河网的水质变化。结果表明:水资源调度对于提高太湖上游湖西区河网水质具有明显作用,约75%的监测断面水质得到改善;区域北部和中西部水质改善程度分别高于南部和东部;调度中后期河网水质改善程度大于初步改善期。
In order to explore the impact of water diversion on the improvement of water quality in the western part of the upper Taihu Lake,simultaneous monitoring of water quantity and quality during the diversion period was carried out to analyze the characteristics of the regional water flow and the water allocation,as well as the changes in the water quality of the regional water network under the water flow during the whole period.Results show that the water diversion has significant effect on improving the water quality of the water network in the upper reaches of Taihu Lake,with about 75%of the monitored sections having improved water quality;the degree of improvement in water quality in the northern and western parts of the region is higher than that in the southern and eastern parts of the region,respectively;the degree of improvement in the water quality of the water network in the middle and late phases of the diversion is greater than that during the initial period.
