湖北省耕地质量空间格局研究

Research on Spatial Pattern of Cultivated Land Quality in Hubei Province

以湖北省为研究区域,对耕地质量状况进行了空间自相关分析,并以此为基础借助克里金插值方法对耕地质量的空间格局进行描述和建模。结果表明,湖北省耕地质量在整体空间上呈现集聚,沿江平原区腹地的仙桃、潜江、天门、荆州为高质量耕地的集聚区,盆周秦巴山区的十堰和神农架以及川鄂湘黔浅山区的恩施为低质量耕地的集聚区;克里金插值生成的湖北省耕地质量的栅格表面直观揭示了全省耕地质量的空间格局。

Taking Hubei province as the study area, the quality of arable land was analyzed by spatial autocorrelation analysis,and on this basis,spatial pattern of arable land quality was the described and did modeling with the kriging interpolation method.The results showed that the quality of arable land in Hubei province presented agglomeration in the whole space; Xiantao,Qianjiang,Tianmen,Jingzhou,hinterland along the river plain,were high quality arable land agglomeration; Shiyan,Shennongjia and Enshi were low quality of arable land; the raster surface of arable land quality in Hubei province that generated by Kriging interpolation directly revealed the spatial pattern of arable land quality of whole province.
