摘要
三江源自然保护区是我国重要的生态环境地区,对其进行生态环境评价,评估当前环境状态十分重要。本文选择囊谦县三江源白扎保护区为评价对象,基于遥感影像对其提取评价因子,为了使评价结果客观准确,有效解决评价因子模糊性的问题,采用层次分析法计算权重集,通过模糊数学与层次分析相结合的综合评判法,得出隶属度关系,进而得到生态环境评价结果。
The Natural Preserved Zone of Sanjiangyuanis an important ecological environment in China.On the ecological environment evaluation and assess the current environment status are very important.This paper chooses Baizha Reserve of the Natural Preserved Zone of Sanjiangyuan in Nangqian County as evaluation object, based on remote sensing image to extract evaluation factors. In order to make the evaluation result objective and accurate, and solve the fuzzy problem of factor problem, it adoptes the Analytic Hierarchy Process to calculate the weight set, and obtains affiliation through the combination of Fuzzy Mathematics and Analytic Hierarchy Process, and ecological environment evaluation result is obtained.
