摘　　要：为充分利用低效园地山坡地开发整理为耕地,提高土地节约集约利用水平,缓解人地矛盾,选取了坡度、土壤、水源、交通等6个评价因子,建立评价体系,在MAPGIS软件支持下编制各评价因子图件,进行各因子图叠加,生成评价单元图,并采用多因素综合法对英德市一定范围的低效园地山坡地进行了耕地适宜性评价。结果表明,在评价的13524.04hm2低效园地山坡地中,当前宜耕的占63.48%,为8585.06hm2,其中园地为610.22hm2,山坡地为7974.84hm2。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 suitability of a range of inefficient garden and hillside in Yingde city was carried out. The results show that in the evaluation of 13 524.04 hm^2 inefficient garden and hillside, the current appropriate cultivating accounted for 63.48%, to 8 585.06 hm^2, including garden of 610.22 hm^2, hillside of 7 974.84 hm^2.
