基于GIS的白山市江源区农用地的适宜性评价

Evaluation of Suitability of Agricultural Land in Jiangyuan District of Baishan City Based on GIS

本文以白山市江源区为研究区域,从多角度对江源区农用土地适宜性进行定量评价。基于Arc GIS的空间分析模块,按照权重值大小对各评价因子进行叠加分析,得出适宜性分级图。研究结果显示,Ⅰ级适宜性区域面积所占比例最小,Ⅲ级区域面积所占比例最大。整体来看,江源区大部分土地不适宜进行农用生产。针对自然因素和人文因素两个方面对江源区的适宜性分布现状进行了分析,为后期农牧业生产规划提供参考。

Taking Jiangyuan district of Baishan city as the research area,the suitability of agricultural land in Jiangyuan district was quantitatively evaluated from multiple perspectives.Using to the spatial analysis module based on Arc GIS,each evaluation factor was superimposed and analyzed according to the weight value,and the suitability classification diagram was obtained.The results show that the area of the I-level suitability area is the smallest,and the area of the III-level area is the largest.Overall,most of the land in Jiangyuan district is not suitable for agricultural production.This paper analyzes the suitability distribution of Jiangyuan region from natural factors and human factors,and provides some references for the following agricultural and animal husbandry production planning.
