In order to reveal the coupling relationship between the spatial autocorrelation of land use and the natural and human factors in loess hilly and mountainous regions, we carried out a case study on Changhe Basin of Jincheng City, and analyzed the land use of the basin and the local spatial autocorrelation pattern, and used GIS and gray system correlation analysis software to quantify the correlation and relation of various types of land and elevation, slope, aspect, effective soil thickness, distance to water area, population density, road network density, distance from residential areas. The results show that:when the weight is 0.5 km, the land use types in the basin show the characteristics of spatial aggregation as a whole spatial autocorrelation; the positive spatial autocorrelation decreases gradually with the increase of the distance; the distribution of cultivated land and grassland show the significant trend of H-H and L-L accumulation; the spatial distribution of forestland, water area and construction land show the significant trend of H-H accumulation. The relationship between the proportion of arable land in each grid and the thickness factor of effective soil layer is the highest. The relationship between the proportion of forestland and the residential area distance factor is the highest. The correlation between the proportion of grassland in each grid and the distance factor of water system is the highest. The highest correlation was found between the proportions of the grid waters and the distance factors from the settlements. The correlation between the proportion of the construction land for each grid and the population density factor is the highest.
