摘要
分析传统耕地坡度分级方法的缺陷,提出利用GIS技术的耕地坡度分级新方法。以枝江市董市镇为例实证,研究制定定量融合指标和工作流程,不仅有效地控制了耕地图斑的数量,而且确保利用耕地坡度分级数据统计汇总的各耕地坡度级面积数据与真实值基本一致,提高了汇总面积数据的精度。
This paper analyzed the shortcomings of traditional classification for farmland slope,proposed the new method for farmland slop classification by use of GIS technology.Taking Dongshi town,Zhijiang City as an example,the integration indicators and work processes were developed.It not only effectively controlled the polygons of arable land,but also to ensure that the farmland slope-area data by use of statistical summary data of farm land slope is consistent with the true value,to improve the accuracy of the data summarized in area.
