The paper aimed to study the spatial variation characteristics of construction land density and its influencing factors. Firstly, Extracted information of Construction land from Landsat-8 images of 2015 remote sensing data, Taking the density of construction land as the observation value to analyze the Global Spatial Autocorrelation of the construction of Wumeng Mountain Land in different scales, The Global Spatial Autocorrelation analysis reveal that construction Wumeng Mountain Land with spatial autocorrelation. The local spatial autocorrelation analysis reveals the local aggregation and local anomaly of the construction land. Secondly, Based on SRTMDEM 90 m resolution Original elevation data, Landsat China inland water information products and Statistical Yearbook of 2015 in Yunnan Province, Guizhou Province and Sichuan Province extract elevation, slope, topographic relief, surface and roughness 4 natural factors and economy, population and other socio-economi factors. then statistical analysis was made on five grades counties at 0.05 significant level. The results indicated that:(1) spatial autocorrelation degree of the distribution of Wumeng Mountain construction land reduced as the increasing of the threshold value;(2) spatial differentiation characteristics of distribution of Wumeng Mountain construction land was obvious difference in space;(3) the distribution of Wumeng Mountain construction land affected by slope, topographic relief, surface and roughness of natural factors and GDP, population density and three major industries of socio-economic factors.
