基于GIS的内蒙古草地牧草生产潜力评价研究——以正镶白旗为例

GIS Based Evaluation of Pasture Potential Productivity in Inner Mongolia——A Case Study in Zhengxiangbai Banner

以内蒙古正镶白旗草地为研究对象,选取了对草地生产力影响较大的7个评价因子,利用层次分析法、专家打分法、指数计算法,建立回归模型和戒上型函数,在ArcGIS软件的地统计方法、空间分析和叠加功能及SPSS软件的数据统计功能的支持下评价研究了正镶白旗牧草生产潜力。结果表明,正镶白旗草地中高度适宜、适宜、基本适宜和不适宜种植牧草的面积分别占草地总面积的8.15%、20.10%、25.34%和46.60%,高度适宜和适宜草地主要分布在正镶白旗南部和中部。

In this study, we selected seven evaluation factors that have greater influence on grassland productivity and used the Analytic Hierarchy Process, experts grading method, exponent method to established regression model and ring type function to assess pasture potential productivity of Zhengxianghai banner in Inner Mongolia based on ArcGIS and SPSS. The results showed that the percentage of highly suitable, suitable, basically suitable and unsuitable areas to establish grass in Zhengxiangbai banner was 8.15%, 20.10%, 25.34%, 46.60%, respectively, the highly suitable and suitable area mainly located in the southern and middle in Zhengxianghai Banner.
