Abstract: Land use intensity index is a measurable indicator that detects the man-land relationship sinceit oould characterize the depth and breadth of land use changes. 'Taking Chenggong of Kunming city asstudy area , this paper computes the land use changes by using Gls quantitative analysis method and sta-tistical analysis method ， and then studies how the human activities effects the land use changes based onland use intensity index and land use dymamic index.'The results show that: 1 ) the land use intensity in-dex instudy area is very different on spatial-temporal scale.From the perspective of time series ， the landuse intensity index increased rapidly from 2013 to 2017，with the average value increasing from 206. 82 to240.81 and the increase is 14.11%. From the perspective of space ,the land intensity index of Cheng-goxng area presents a trend of high in the west and low in the east. 2 ) 'The intensity od land use in Cheng-gong district is mainly influenced and driven by urban land use such as real estate development and roadconstruction ,but is less affected by human activities such as agricultural production.
