Abstract: Improving the rural human settlement environment is important for rural revitalization and building a welloff society in an allround way. Scientific evaluation of the construction of rural human settlement environment can provide decision-making basis for its optimization in China. Here, the coefficient of variation, Gini coefficient, Theil index, and convergence/divergence method were used to analyze the spatial-temporal variation of rural human settlement environment in China’s 30 provinces and three economic zones from 2006 to 2015. Results showed that China’s rural human settlement (RHS) score increased by 6.26%. The spatial pattern of “East, Middle, West” descending steps in the rural human settlement environment remained unchanged. The overall difference of human settlement environment in the rural areas tended to shrink, and the coefficient of variation, Gini coefficient and Theil index decreased by 5.32%, 6.50% and 10.59% respectively. The rural human settlement tended to be improved for China’s provinces mainly due to the improvement of rural living conditions, but with partial deterioration of the situation. The primary constraint factor of rural human settlement was basic public services, followed by environmental quality, and economic and social factors.
