摘要：

通过实地调研、资料解析、模型计算等多种方式获取数据,对2005～2009年贡湖环湖带河网污染物负荷及输移规律进行深入研究。结果表明:①与贡湖湾进行水体交换的河道主要为苏州河网及望虞河。望虞河总体流量表现为出湖略大于入湖,污染负荷总体表现为入湖;苏州河网总体流量及污染负荷均表现为净入湖状态。②望虞河平均入湖污染负荷量COD为416.42 t/a,TP为29.84 t/a,TN为598.32 t/a,NH3-N为254.28 t/a;苏州河网平均入湖污染负荷量COD为481.73 t/a,TP为16.81 t/a,TN为540.87 t/a,NH3-N为250.66 t/a。③汛期,大部分污染负荷经苏州南部口门随水流进入贡湖;非汛期,贡湖湖水由南部口门进入河网,向东北流动进入浒光运河等周边水体。

摘要：

By methods of field investigation,material analysis and model calculation etc.,the situation of Pollutant load and transportation pattern in the lake belt area of Gonghu Bay during 2005-2009 were analyzed.The results showed that Wangyu River and river network in Suzhou area exchanged water with Gonghu Bay.For Wangyu River,the overall flows went to Gonghu Bay while the overall pollution led to the other side;For Suzhou river network,both flows and pollution loads transported into the bay;The average pollutant loads transported by Wangyu River were COD of 416.42 t/a,TP of 29.84 t/a,TN of 598.32 t/a,NH3-N of 254.28 t/a,while the loads for Suzhou river were COD of 481.73 t/a,TP of 16.81 t/a,TN of 540.87 t/a,and NH3-N of 250.66 t/a.In flood season,most of the pollution led together with the flows transport into Gonghu Bay from southern entrances.In other period,flows of Gonghu Bay transported into river network from southern entrances and took the terrestrial pollutant led into the surrounding water body such as Huguang River.
