摘要
本文以湖北为案例区,选取气候、水文地貌、土壤和社会经济4个方面12个评价因子构建指标体系,采用AHP方法确定指标权重,在栅格尺度上开展耕地适宜性评价。结果表明:(1)AHP方法能够将复杂问题中的各种因素划分为相互联系的有序层次,使之条理化,适合用于确定耕地适宜性评价指标体系中各指标的权重;(2)栅格数据由于便于空间分析,因此适合用于耕地适宜性评价;(3)高度适宜和中度适宜的耕地面积占湖北省土地面积的一半。
Taking Hubei province as a case,four factors（climate,hydrology landscape,soil and socio-economic）were selected to make up the index system,and AHP was applied to calculate the weight of each index,then cultivated land suitability evaluation was developed based-on raster data.Results show：（1）AHP can make the various factors of complex problems into a linked orderly hierarchy and principled.It is suitable for decidinge each target＇s weight in index system for cultivated land suitability evaluation;（2）Raster dataset is fit to cultivated land suitability evaluation because of its convenience to the spatial analysis;（3）the highly and moderately suitable cultivated land is account for 50 percent in land area of Hubei province.
