摘要
【目的】评估大东湖水系建成前后水质的变化情况。【方法】以已建成的大东湖生态水网工程中的东沙渠段为研究对象,搜集现有文献资料,统计分析了东沙渠连通工程对外沙湖及水果湖水质的影响。【结果】东沙渠连通后外沙湖仍是劣V类水质,但其主要污染物种类减少,且污染物量也有明显降低趋势;水果湖水质为IV或V类水质,无明显主要污染物质。【结论】东沙渠连通工程对外沙湖水质有较显著的改善作用,对水果湖的影响不明显。
【Objective】Assess the changes in water quality before and after the completion of the Dadong Lake water system.【Methods】This paper took the Dongsha Canal section of the completed Dadong Lake Ecological Water Network Project as the research object,and collected the existing data,then statistically analyzed the impact of the Dongsha Canal Connection Project on the water quality of the Waishahu lake and Fruit lake.【Results】After the Dongsha Canal was connected,the water quality of Waishahu Lake was still poor Grade V,but its main pollutants species were obviously reduced,and the pollutant content also decreased significantly.The water quality of the Fruit Lake was Grade IV or Grade V,and there were no obvious major pollutants.【Conclusion】The Unicom Project has a significant effect on the water quality of the Waishahu Lake,while the effect on the Fruit lake is not obvious.
