摘  要:
为合理开发、利用喀斯特地区土地资源提供科学依据,以贵州省仁怀市为例,在GIS技术支持下,选取影响作物种植的自身性状和开发难易程度等因素建立指标体系,对仁怀市低丘缓坡土地开发潜力进行了评价。结果表明:仁怀市低丘缓坡土地具有开发潜力的有7 710.41hm2,其中,高、中、低、极低开发潜力土地面积分别为535.93hm2、2 453.06hm2、4 184.94hm2和536.48hm2,占参评土地总面积的6.95%、31.81%、54.28%和6.96%。高、中开发潜力土地主要分布在中部,低、极低开发潜力土地主要分布在西部地区。

摘  要:
In order to provide the scientific basis for land exploitation in karst regions,in the support of GIS,the authors established the index system from the perspective of the factors affecting crop planting and the difficulty of exploitation,and evaluated the potential of low mountains and hills in Renhuai City.The results show that there are 7 710.41ha high potential land,medium potential land,low potential land,very low potential land are respectively 535.93ha,2 453.06ha,4 184.94ha and 536.48ha which accounts for 6.95%,31.81%,54.28%and 6.96%respectively.High potential land and medium potential land are mainly distributed in the central region,low potential land and very low potential land are mainly distributed in the western region.
