受损村庄搬迁安置在我国干旱半干旱采煤矿区是一项非常复杂的工作。由于地形复杂、水源有限、风沙侵袭等原因,干旱半干旱矿区宜居场所其实十分有限,因此搬迁安置前必须进行矿区村庄人居环境宜居性评价,以辅助搬迁决策。本文以大同南郊采煤矿区为例,通过实地调查和遥感分析,构建了以基本生活条件和基本生产条件为评价因素的宜居性评价指标体系,采用等级-分值法和层次分析法构建评价模型,对矿区103个村庄的人居环境质量及其宜居性进行了评价。评价结果表明,人居环境极差、较差、较好、好的村庄分别有51个、20个、8个、24个。与矿区破坏实际情况对比的结果表明,该评价指标体系合理,评价模型有效,可用于辅助干旱半干旱采煤矿区的村庄搬迁决策。
The relocation and resettlement of damaged villages is a very complicated work in the arid and semi-arid mining area of China.Due to the complex terrain,limited water resources,sand invasion and some other reasons,the suitable site in arid and semi-arid area is very limited,so the evaluation of human settlement livability must be carried out before relocation and resettlement,in order to assist the relocation decision.In this paper,the mining area in Nanjiao district of Datong city are taken as a case,through field surveys and remote sensing analysis,constructs the basic living and product conditions as the evaluation factors of livability evaluation index system,modeling by grade-score method and analytic hierarchy process method,to evaluate the human settlement quality and livability of 103 villages.It shows that there are 51 villages which are in a very poor living environment.there are 20 villages which are in a poor living environment.There are 8villages with better human settlement.Actually,there are 24 villages with best human settlement.The results elaborat that the evaluation indexes system is reasonable,the evaluation model is effective,and can be used in making the decision of the village relocation in the coal mining area of semi-arid and semi-arid regions.
