沙湖湿地的生态环境健康评价的研究

Studies on the Evaluating Ecosystem Health of Shahu

通过对生态系统健康评价体系的研究,以沙湖为例进行论证,最终得出沙湖生态系统健康度为0.32,属于不健康,制约沙湖不健康的疾病因子在于:湿地的补水水质差,导致湿地水质污染加重,富营养化现象严重,并且由于人为因素,导致物种多样性逐年下降,以上因素最终导致了沙湖湿地生态系统抗干扰能力下降,湖区湿地健康水平较低,根据对沙湖湿地功能的分析,最终设计出了沙湖湿地生态系统健康恢复技术方案。

On the basis of research on the Domestic and international the ecosystem health status quo,in order to verify the reliability of the given evaluation system,giving an example as Shahu,the health degree of Shahu ecosystem is calculated to be 0.32 in the end,and it is unhealty.The unhealthy constraining factor of Shahu are poor water quality of wetland which leads to the water pollution of Wetlands,Serious eutrophication and annually declining of species diversity.The above factors eventually lead to the non-interference ability decline of wetland ecosystem in Shahu.And Lake wetlands in Shahu are poor healthy.According to the analysis of wetland function in Shahu,the wetland ecosystem health restoration programme of Shahu is designed finally.
