摘要
衡水湖是华北平原具有独特自然景观的国家级湿地和鸟类自然保护区,富营养化是其面临的一个主要问题。通过对衡水湖水体的主要营养物质氮、磷的污染特征、来源、成因分析以及对水体的富营养化现状进行评价,表明衡水湖的水质状况近年来得到了一定程度的改善,但氮、磷的污染仍相当严重,污染程度冬春季较轻,夏秋季节较重,富营养化程度从中营养到轻度、中度富营养。
The Hengshui lake is the North China Plain has the unique natural landscape state-level wetland and the birds nature protection area, the eutrophication question is a main question which it faces. To the Hengshui lake water body main nutrients nitrogen, the phosphorus pollution characteristic, the origin, the origin have carried on the analysis, has carried on the appraisal to the water body eutrophication present situation, finally indicated： The Hengshui lake water quality condition recent years was improved certain degree, but the nitrogen, the phosphorus pollution quite was still serious; The pollution degree winter, the spring are light, then summer fall season heavy, eutrophication degree nutrition to mild, moderate rich nutrition.
