摘要
以云龙湖东、西湖两大不同功能区为对象,研究两大不同功能区富营养状况程度,为云龙湖富营养化的合理预测、防治提供基础和理论依据。在云龙湖东、西两湖区各设3个采样点,对两大不同功能区进行了调查研究。主要测定了总氮、总磷、透明度和叶绿素物化指标。结果表明:云龙湖东、西两湖已处于富营养化状态,且西湖区要比东湖区严重。说明功能区的不同,将会对水体富营养化的程度造成影响。
Yunlong Lake is a shallow lake located in the southern suburb of Xuzhou City.Its surface area is 5.8 km2.Now it is already listed in province-level scenic spots.Currently,Yunlong Lake is a famous scenic spot and also functions as a reservoir,a fishery,a municipal facility for flood control and so on.In these years,eutrophication has happened to Yunlong lake.There are now some researchers only from the angle of total eutrophication.In this paper,the eastern and western part of Yunlong Lake are selected as subjects.It serves as a reasonable foundation and research basis for eutrophication in Yunlong Lake.In the whole lake,six sampling points are set.Three points are set in eastern and western parts respectively.The water body＇s eutrophication of different function areas is analyzed in this paper.TN,TP,SD,chlorophyll are measured to evaluate the degree of eutrophication of Yunlong Lake.It can be concluded from the analysis that the eastern and western parts of Yunlong Lake are already eutrophic,the western part is more severe than the eastern part.It is shown that the water quality of the western and eastern parts is different because of their distinct functions.
