白洋淀生态承载力研究

Primary Study of Ecological Carrying Capacity in Baiyangdian Lake

白洋淀是华北地区最大的淡水湖泊。近年来由于水体的污染造成白洋淀地区的生态遭到严重的破坏,以致于其生态承载力下降。根据白洋淀生态系统构成,运用层次分析法对白洋淀水生生态系统承载力和陆地生态系统承载力进行了初步的研究,在丰水年时,水资源为中等承载,水质也比较好;但若在平、枯水年时,二者的承载力都会下降。

Baiyangdian Lake is the largest freshwater lake in north China. Recently its ecological environment is deteriorated seriously because of the water pollution leading to the descent of its ecological carrying capacity. This paper has used analytic hierarchical process （AHP） and has studied ecological carrying capacity in Baiyangdian Lake according to the Baiyangdian Lake＇s ecosystem structure.
