摘　　要：水体富营养化与水体中磷的含量有着密切联系,湖泊沉积物是湖泊水体中磷的主要储存场所,也是湖泊水体中内源性磷的主要来源。了解沉积物中磷的污染程度及其存在形态,对于从根本上解决湖泊富营养化问题有重大的意义。以武汉市汤逊湖为研究对象,在汤逊湖共布置131个沉积物采样点位,调查汤逊湖沉积物中磷的污染状况,并选择其中部分点位做分级磷的提取分析实验,调查沉积物中磷的存在形态及其分布特征。Water eutrophication is closely related to the phosphorus content, and the sediments are the main sto-rage places of phosphorus as well as the endogenous phosphorus of lake. Study of the degree of phosphorus pollution in sediments and its existing form is of great significance to fundamentally solve the lake eutrophication problem. Taking Tangxun Lake as case study, 131 sediment sampling points are settled to investigate the phosphorus pollution, and some of the points are selected for the extraction and analysis experiment of graded phosphorus to study the forms of phosphorus and its distribution characteristics.
