Abstract Jixian County in Tianjin City is a national ecological demonstration county. In order to study the influence of landform on land use dynamic change, the authors extracted the change information of land use in Jixian County for 10 years on the basis of TM images in 2001 and 2011 with post-classification comparison. Two terrain factors for relief degrees of land surface and slope were generated using spatial analysis algorithms. The distribution and variation features of the two land use types in different terrain features and the land use change were analyzed quantitatively in two aspects of type conversion and dynamic degree. The correlation between the change of land use type and the relief and slope was also analyzed. In addition, the influencing factors of land use change were investigated. The results show that the area of waters, farmland and residential land which expanded by 2.46% has been increased in the past 10 years. The conversion of land use type are mainly from woodland to farmland and residential land, from farmland to woodland and residential land, and from unused land to farmland and residential land. The landform has a significant influence on the dynamic change of land use. The residential land has increased most conspicuously, followed by water area, whereas woodland decreases most obviously. In low relief and moderate relief landform, residential land has increased most obviously; in mountainous relief, residential land has somewhat increased; in high mountain relief landform, only woodland and unused land has changed a little. The research on geographic and geomorphic impact on land use dynamic change is of guidance significance for ecological protection. The results achieved by the authors can provide a scientific basis for land use in partly mountainous districts and counties.
