衡水湖香蒲群落调查及其对水质的影响

Investigation on Typha Angustifolia Community in Hengshui Lake and its Influence on Water Quality

对衡水湖香蒲群落类型及其生长条件的调查研究,香蒲群落中挺水植物种类组成的数量分析,不同区域内水体的某些水质指标测定表明:衡水湖水体严重污染主要是有机物污染.其原因是香蒲长期过度繁殖及其粗放管理,湖中积累了大量香蒲残体,在高温时期,大量分解所致.同时提出了治理污染的措施.

This paper, through the investigation and study on the type and the growth conditions of typha angustifolia community in Hengshui Lake, the quantity analysis of the species composition of the emergent plant in typha angustifolia community and the measurement of the water quality in different water areas, shows that the water in Hengshui Lake is polluted by organic substance, and the reason for which is that the excessive breeding of typha angustifolia and poor management of it result in the accumulation of a great deal of dead plants in the lake which decompose greatly in high temperature season. And it also presents the measure of managing the pollution.
