坡耕地是耕地资源的重要组成部分,有着巨大的资源利用潜力。采用专题调查方法,通过构建坡耕地坡度特征指数等分析方法,对河南省坡耕地现状进行了定量分析,结果表明:2010年,河南省坡耕地面积达到789 630.22 hm2,占调查区域耕地总面积的23.15%,坡耕地坡度特征指数为0.21,坡耕地总体坡度较缓,坡耕地总体治理度39.99%,治理水平相对较低,坡耕地亟待治理。基于坡耕地分布及结构的区域性差异,未来坡耕地治理的难度也具有区域性差异。
Slope cultivated land is an important part of arable land resources, with huge potential for resource utilization. Using the method of special survey, the paper analyzed the status quo of slope farmland in Henan Province by means of analyzing the slope characteristic index of slope farmland. The results showed that in 2010, the slope farmland in Henan Province reached 789 630.22 hm2, accounting for the total area of cultivated land in the surveyed area 23.15%. The gradient index of slope cultivated land is 0.21. The overall slope of sloping farmland is relatively gentle. The overall control degree of sloping farmland is 39.99%, and the management level is relatively low. Based on the regional differences of slope farmland distribution and structure, the difficulty of slope farmland management in the future also has regional differences.
