摘 要:研究以2015年高宝邵伯湖整个湖区的水质、底质监测数据为基础,对水质调查状况进行了调查与评价,结果表明:高宝邵伯湖的渔业生态环境状况总体良好,底质监测指标全部达标;但湖内部分水体受到有机污染,并出现富营养化。因此,必须加强对高宝邵伯湖水域环境保护与渔业管理工作,并对治理工作进行整理总结,为将来高宝邵伯湖水质的治理改善工作提供重要的基本资料和科学依据。

Abstract:In this study,a survey was conducted to evaluate the water quality of Gaobaoshaobo Lake based on the monitoring data of the water and sediment in 2015. The results show that ecological condition for Fishery in Gaobaoshaobo Lake is in good condition and the sediment indicators all reach the standard. However,some internal bodies of the water were influenced by organic pollution which caused eutrophication. Therefore,water quality improvement in Gaobaoshaobo Lake must be strengthened,and the documents and data in this process must be collected to provide scientific basis for environmental protection of this lake in the future.

高宝邵伯湖是江苏省第三大湖,包括高邮湖、宝应湖、邵伯湖3个独立的湖泊,3湖自北向南沿里运河呈串珠状排列,辖于苏、皖2省,介于东经119°01′~119°30′,北纬32°27′~33°14′,总面积936km2。3个独立的湖泊,3湖自北向南沿里运河呈串珠状排列,辖于苏、皖2省,介于东经119°01′~119°30′,北纬32°27′~33°14′,总面积936km2。3湖水系贯通,是淮河入江的泄洪、蓄洪之道。高邮湖是淮水入江的主要通道,属大型过水性湖泊,水深为1.2~1.8m,入湖水量大,多年平均入湖径流量为2.33×1010m3,其中90%来自洪泽湖。邵伯湖处于高邮湖下游,湖泊类型和高邮湖相似,由于湖盆面积小、泄洪能力低,过水性特征比高邮湖更为显著。宝应湖自1969年建成大汕于隔堤截断与高邮湖的联系后成为封闭式河道型湖泊。高宝邵伯湖地区属湿润的亚热带季风气候,降水丰沛,渔业资源丰富,是重要的淡水渔业基地。近年来,由于围湖造田、湖区周围工业、农业、生活废水、城镇建设以及湖泊网围养殖区的高速度发展,高宝邵伯湖水环境质量逐步下降。……
