[Objective] Taking Xingcheng City

Liaoning Province as the research area

this study evaluates and analyzes the topographic conditions of arable land in order to provide the basis for guiding crop cultivation

arable land quality evaluation

soil erosion and debris flow disaster prevention

and ecological environmental protection of the arable land.[Methods] Based on the digital elevation model (DEM)

the slope

aspect

surface undulation

plane curvature and terrain roughness were selected as the evaluation factors

to evaluate the cultivated land topographic conditions by the multi-factor weighted comprehensive evaluation.[Results] The terrain condition of the arable land of Xingcheng City was as follows:85.57% of the total arable land was good arable land of grade Ⅰ and Ⅱ

14.17% was general arable land of grade Ⅲ and Ⅳ

and only 0.26% was grade Ⅴ.[Conclusion] The topographic conditions of arable land in Xingcheng City are relatively good as a whole. However

few arable land is in poor topographic conditions

which is not suitable to reclaim and needs to be returned to farmland.
