| 摘 要： | This paper introduced the theory and approaches of building driving force models revealing the changes in land utilization level by integrating RS, GPS, and GIS technologies based on the example of Yuanmou County of Yunnan Province. We first created the land utilization type database, natural driving forces for land utilization database, and human driving forces for land utilization database. Then we obtained the dependent and the independent variables of changes in land utilization level by exploring various data. Lastly we screened major factors affecting changes in land utilization level by using the powerful spatial correlation analysis and main component analysis module of GIS and obtained a multivariable linear regression model of the changes in land utilization level by using GIS spatial regression analysis module.

| Abstract: | This paper introduced the theory and approaches of building driving force models revealing the changes in land utilization
level by integrating RS, GPS, and GIS technologies based on the example of Yuanmou County of Yunnan Province. We first created
the land utilization type database, natural driving forces for land utilization database, and human driving forces for land
utilization database. Then we obtained the dependent and the independent variables of changes in land utilization level by
exploring various data. Lastly we screened major factors affecting changes in land utilization level by using the powerful
spatial correlation analysis and main component analysis module of GIS and obtained a multivariable linear regression model
of the changes in land utilization level by using GIS spatial regression analysis module.
