As global environment deteriorates, the study on land use change and its driving forces becomes an important research subject in the field of land science. The relationship between terrain variables and land use has become an important part of land use/cover change. Based on the remote sensing data of TM images in 1985, 1995, 2000, and 2010, we took the poverty area around Beijing and Tianjin as an example to analyze the terrain gradient characteristics of land use change by geo-informatics map analysis. In order to provide some recommendations on land use planning and land use management, we also explored the impact of topography on the selection of land use pattern and the causes of the terrain gradient effect of land use change. The results showed that 1) From 1985 to 2010 the land use types mainly distributed on the area of terrain relief under 200 m as well as slope of slope (SOS)) less than 15[degrees].
