灾害移民主要是指由突发型自然灾害引起的人口迁移。灾害移民安置的前提是灾害移民环境容量分析,涉及到灾区的资源、环境、社会、经济、生态、地质条件等多种因素。本文运用AHP模糊评价法对汶川地震重灾区10县环境容量进行综合评价,认为对于超出土地承载能力的地震灾害移民是否外迁,要具体分析该地区的综合环境容量特征,分析灾害区资源环境、社会环境、经济环境和自然地理环境等方面的具体情势,并以此实施灾害移民的差异化重建策略。
Disaster immigrants mainly refers to the population caused by unexpected natural disasters. Disaster resettlement is based on the analysis of environmental capacity of disaster resettlement and involves many factors such as resources, environment, society, economy, ecology and geological conditions. In this paper, AHP fuzzy evaluation method is used to evaluate the environmental capacity in 10 counties severely affected by Wenchuan earthquake. It is considered that whether the resettlement of earthquake disaster beyond the carrying capacity of the land is relocated or not, the comprehensive environmental capacity characteristics of the area should be analyzed specifically, Social environment, economic environment and natural geography environment, and so on. In this way, we should implement the strategy of differentiated reconstruction of disaster immigrants.
