基于GIS的耕地整理潜力评价研究

Study on the Potential Appraisal of Arable Land Consolidation Based on GIS

针对我国目前耕地整理潜力分析中存在的不足之处,构建新增耕地系数、耕地产出提高率、防护林比重提高率和田块大小提高率的评价指标体系,以湖南省衡南县车江镇为例,详细介绍了基于GIS的耕地整理潜力评价的基本思路和步骤,结果表明该方法具有科学性和可操作性。

Aiming at the current problems in the analysis of arable land consolidation, the appraisal index for potential analysis is established, including newly-added farmland coefficient, output increase ratio, forest increasing ratio and fields＇ size increase ratio. Taking the Chejiang Town of Hengnan County, Hunan Province as an example, the procedures of arable land consolidation potential appraisal based on GIS are introduced in detail. The result proves that this method is scientific and feasible.
