| 摘 要： | 定量评价湿地的生态质量,对保护湿地生态环境具有重要意义。以湿地生态系统服务功能、生态环境保护功能、湿地资源评价为综合评价层,以12个生态评价因子为指标层,构建博斯腾湖湿地生态质量定量评价指标体系,采用层次分析法(AHP)以及专家评议的方法,计算出各生态评价因子的权重,使用问卷调查法得出各因子的得分,最终通过综合评价指数(CEI)来表达湿地的生态环境质量。分析结果表明:博斯腾湖湿地当前生态质量级别为一般。在此基础上,进一步分析了湿地退化的原因,提出了维持湿地可持续发展的保护措施。通过博斯腾湖湿地生态质量的定量评价,对掌握现阶段博斯腾湖的生态环境状况,维持湿地的可持续发展有着极为重要的指导意义。

| Abstract: | Quantitative ecological evaluation on the Bosten Lake wetlands plays a very important role,through which we can know the conditions of ecological environment of the Bosten Lake wetlands at present and then we should take some effective measures to maintain the sustainable development of the Bosten Lake wetlands.By using analytic hierarchy process,the index system of ecological evaluation was constructed which was composed of three synthetic ecological evaluation layers and twelve ecological evaluation facto... |
