摘　　要：宜机化改造是解决丘陵山区机械化发展不平衡的必由之路,在改造之前进行适宜性评价能有效提高改造过程中的科学性和针对性。选取地块形状指数、连片性、农村建筑、交通条件、地表粗糙度、地形起伏度6个宜机化限制因子,以重庆市开州区一个待改造项目为例,结合层次分析法(Analytic Hierarchy Process, AHP)和K-means聚类分析方法以及模糊理论,以ArcGIS为平台构建丘陵山地宜机化改造适宜性综合评价模型。结果表明,各影响因子的权重排序为:地形起伏度>地表粗糙度>连片性>形状指数>交通条件>农村建筑,为后续的加权叠加分析提供基础依据;评价目标的宜机化改造适宜性综合评价结果为比较适宜,其中适宜、比较适宜、比较不适宜、不适宜的区域分别占改造区域面积的41.87%、44.79%、12.8%、0.54%。基于ArcGIS的适宜性评价方法能有效进行丘陵耕地适宜性评价,提高宜机化改造效率,加快丘陵耕地机械化进程。The suitable mechanization transformation is the only way to address the imbalance of the mechanization development in hilly and mountainous areas.The suitability evaluation before initiating the transformation can effectively increase scientificity and targeted effectiveness throughout the transformation process.In this study,six suitability limiting factors including shape index,connectivity,rural buildings,transportation condition,surface roughness,and terrain variability were selected,taking a project in Kaizhou District of Chongqing as an example,a comprehensive evaluation model for terrace mechanization transformation suitability was constructed using Analytic Hierarchy Process(AHP)method,Kmeans clustering analysis and fuzzy theory on the platform of ArcGIS.The results indicated that the weight ranking of each influencing factor was as follows:terrain variability>surface roughness>connectivity>shape index>transportation condition>rural buildings.This result provided a basis for subsequent weighted overlay analysis.The comprehensive evaluation result of suitability for the transformation objective was relatively suitable,with suitable,relatively suitable,relatively unsuitable,and unsuitable areas accounting for 41.87%,44.79%,12.8%,and 0.54%of the transformation area,respectively.The suitability evaluation method based on ArcGIS can effectively evaluate the suitability of hilly farmland,improve the efficiency of mechanized transformation,accelerate the process of mechanization of hilly farmland.
