| Abstract: | In order to take full advantage of inefficient garden and hillside into cultivated land, improve land conservation and intensive utilization levels and alleviate the man-land contradiction, this paper selected slope, soil, water, transportation and other aspects of six evaluation factors to establish an evaluation system. Based on MAPGIS, compile the evaluation factor maps and overlay of them, then form evaluation unit map. Final adopting of an integrated multi-factor method, evaluation of cultivated land s... |
