It is of great significance to promote the overall development of urban and rural areas by clarifying the influencing factors of the spatial pattern evolution of rural settlements in karst trough valley area. Based on the rural settlement data of 1960, 2000 and 2017 in Yinjiang County, we used GIS spatial distribution model and spatial statistical measurement model to quantitatively characterize the evolution characteristics of rural settlement scale and spatial distribution, and explore the evolution of time and space patterns of settlements by natural and human factors. The results show that:(1)the area of rural settlements in Yinjiang County increased by 2 721.41 hm2 from 1960 to 2017, the average area of plaque decreased from 10.87 hm2 to 2.79 hm2, and the plaque density increased from 0.18 per km2 to 1.12 per km2; from large-scale, low-density to small-scale, high-density evolution, the center of gravity of the settlement moved from the southeast to the southeast and then to the southwest;(2)the range of high nuclear density regions expanded to the east, showing spatial agglomeration distribution; the cluster plaques in the three periods were all high-value clusters, and the spatial differentiation of cold hotspots was obvious; the cluster density and size distribution were negatively correlated, and the small-scale and high-density features were prominent;(3)the natural factors such as topographic rivers were the dominant factors in the spatial pattern evolution of rural settlements in Yinjiang County; population growth and economic development were the endogenous dynamics of settlement evolution; family planning, administrative division adjustment, disaster and rural development policies were the external thrust for promoting the development of settlements; the settlement gathered towards the traffic line.
