Abstract: The quality development of rural human settlement environment is an important means to build an ecologically livable modern countryside under the background of rural revitalization strategy.This paper constructed the rural human settlement environment quality index system from the perspective of "three-life" space from three dimensions: production environment,living environment and ecological environment.It used entropy weight TOPSIS model to evaluated the development level of rural human settlement environment quality in Gansu Province from 2008 to 2020.The study found that Gansu province rural living environment quality development was relatively slow,the comprehensive index of the overall low development level in different province city states,Jiayuguan and Jiuquan were in the leading position,Zhangye,Jinchang and Wuwei were next,Lanzhou,Baiyin,Tianshui,Qingyang,Dingxi and Longnan were generally developed,and Pingliang,Linxia Autonomous Prefecture and Gannan Autonomous Prefecture were next to other cities and states.Among them,the ecological and living indicators had a great impact on the development of rural human settlements in Gansu Province.Therefore,it proposed a differentiated governance strategy of "taking measures according to local conditions and applying policies according to different levels" for the cities and states divided into different levels,which provided decision-making basis for promoting the governance of rural human settlements in Gansu Province.
