Analysis of socio-economic driving forces on land use and land cover change (LUCC) is one of the hot issues of LUCC research. This paper analyzed the socio-economic driving forces of LUCC in the study area by correlation analysis method and PCA (principal component analysis) method. The study also constructed the model between population and land use degree and analyzed the disturbance of human activities on different landscapes based on the estimated disturbance index. The results showed that the main socio-economic driving forces are population factors, economic factors, technological factors and regional socio-economic development degree. The disturbance of human activities to construction and urban area is the most notable, second is woodland, plantation and water area. The model not only can analyze the relationship between population and land use degree but also have certain prediction function.
