Rural human settlement environment improvement: process, status and China’s sample

China's victory over poverty is globally felt, significantly contributing to global poverty reduction. China has comprehensively promoted implementation the great project of improving rural human settlement environment, which has completely changed the poor environment in rural areas. From getting rid of the dirty and messy to pursuing the beauty of the countryside, improving the Chinese rural human settlement environment has achieved remarkable results. On the basis of clarifying the connotation of rural human settlement environment improvement and combing the development context of rural human settlement environment in China, this paper constructs an evaluation index system of rural human settlement environment quality, and uses the coefficient of variation method and the weighted summation method to analyze the spatial and temporal characteristics of rural human settlement environment quality in 31 provinces of China, and carries out type identification, and designs differentiated improvement strategies. The results showed that: (1) the environmental quality of Chinese rural people is increasing year by year, which can be divided into three stages: slow growth stage, fast growth stage and high growth stage. The growth rate is closely related to the strength of the national policy guidance; (2) there are significant regional differences in the level of rural human settlement environment in China, showing a spatial pattern of "high in the east and low in the west" on the whole, and the development level of each subsystem shows an upward trend with a large increase, which is basically consistent with the distribution trend of China's economic development level. (3) According to the development level of rural human settlement environment quality, it can be divided into lagged type, single system leading type, compound system leading type and comprehensive type, and combined with the type characteristics to promote the rural human settlement environment remediation. The research results provide directional guidance for the cause of rural human settlement environment, and provide China's experience for the world's rural human settlement environment cause, and play a model role.
