吉林省典型湿地生态评价

湿地生态评价是湿地景观规划、管理和保护的基础,以湿地功能为基本线索,以植被为标志,建立湿地生态评价目标系统(包括湿地生态系统服务功能、湿地生态保护功能和湿地资源等3个综合指标,其中还包括15个生态评价因子).通过运用层次分析法(Analytic Hierarchy Process简称AHP)对生态评价因子的等级化处理,评价指标权重的确定,计算出各生态评价因子的综合评价指数(CEI).根据综合评价指数将吉林省典型湿地划分为3种不同湿地生态现状类型,即当CEI＞0.7时,表示湿地生态环境质量较好,依次是莫莫格湿地、长白山湿地、三湖湿地和向海湿地;当0.7＞CEI＞0.5时,表示湿地生态环境质量一般,依次是敬信湿地和查干湖湿地;当CEI＜0.5时,表示湿地生态环境质量较差,依次是大布苏湿地.在此基础上,提出区域湿地的有序开发与环境保护协调发展的基本思路.

Ecological evaluation on typical wetlands in Jilin Province

Ecological evaluation on wetland is a basis for wetland landscape plannng,magage ment and conservation.Focused on the wetland function and vegetation,this paper presented a synthetic ecological evaluation system,which included three integrat ed indices,i.e.,wetland’s ecological evaluation factors.These indices were grad ed and weighed by using the Analytic Hierarchy Process(AHP),and the composite ev aluation indices(CEI) were calculated.According to CEI,typical wtlands i n Jilin Province were classified into three different ecological types,i.e.,wetl and with normal ecolocial environment (CEI >0 7),wetland with critical ecol o cial environment(0 5< CEI ≤0 7),and wetland with extremely critical ecolog ical environment(CEI ≥0 5abstractIt was proved that the eco environment of wetla nd in the western Jilin Province was weak,and eco service function was very sen sitive.A basic idea of compatible development and exploration with environment p rotection was proposed.
