为了解太湖流域河道的营养状况,研究了太湖北部河网区水体营养元素和形态氮的分布与成因.样品按水系划分为宜兴河网区、太滆港道区、太湖湖区水系(北部和东部沿岸区),结果表明:总磷为太滆港道区最大(0.98mg/L),氨氮为东部沿岸区最大(0.60mg/L),总氮与其他形态氮为宜兴河网区最大,北部沿岸区各指标都较大.按污染源划分为工业、农业、生活及畜禽养殖污染源,结果表明:工业污染源总磷和氮素都最高,农业污染源总氮和硝态氮含量较高,铵态氮含量较低;牛活污染和畜禽养殖水体中总磷和铵态氮含量较高,硝态氮含量较低.麦季采样水体总氮浓度较高,形态氮以NO_3~--N为主,NH~+_4-N浓度较低为特征.结合区域和污染源对比分析,宜兴河网区以农业污染源为主,太滆港道区工业污染源为主,北部沿岸区以畜禽养殖为主,东部沿岸区以生活污染源为主.

Distributions of nutrient elements and nitrogen species in rivers and their sources were studied in order to identify nutrient level of river network in north of Taihu Lake.Water samples in river network were divided into Yixing area,Talge area and Taihu Lake aquatic system at northern and eastern shores.Results showed that Talge area had the highest phosphorus 0.98mg/L,eastern shore areas had the highest NH_4~+-N 0.60mg/L,and Yixing area had the highest nitrogen and nitrogen species.Pollutant Sources concerning with nutrients were divided into industrial,agricultural,domestic and livestock and poultry sources.Results showed that TP,TN and nitrogen species were the highest concentrations in industrial Souses,middle concentrations in living and agricultural sewage.Sampling wheat season was high in total nitrogen concentration of water bodies,with characterization of NO_3~--N as dominant and NH~+_4-N concentration relatively low.Combined with analysis of regional and pollutant source,Yixing area is mainly agricultural Source,Talge area is dominant by industrial source,northern shore is mainly from livestock and poultry and eastern shore area is mainly influenced by domestic Source.
