鄱阳湖湿地生态功能重要性分区

摘要

在分析鄱阳湖湿地自然环境特征和湿地生态系统服务功能特征基础上,利用GIs技术,对鄱阳湖湿地范围进行界定,湿地面积为3886km2.基于湿地生态环境保护和社会经济发展总体要求,按照生态功能区划原理,对湿地进行生态功能重要性分区研究.根据湿地生态功能重要性评价结果将湿地分为极重要区、高度重要区、重要区、一般重要区四个区域,其面积分别是125km2,1387km2,2064km2和310km2.针对分区结果,文中提出了湿地生态保护对策与建议.%The boundary of wetlands of Lake Poyang was analyzed with RS and GIS tools based on the natural environment and ecological function. The area of wetlands was 3886km2. The importance of ecological function was appraised based eco-environmental protection and social-economic development according to the theory of ecological function regionalizafion. According to the result of ecological function importance appraising, the wetlands could be divided into four zones as vital important zone, high degree important zone, important zone, and general important zone, with areas of 12.5km2 , 1387km2 , 2064 km2 and 310km2 , respectively.Some suggestions and countermeasures for wetlands protection were also put forward.
