乌蒙山区土地利用垂直分布特征——以云南省寻甸县为例

Vertical distribution characteristics of land use in Wumeng Mountain area:A case study of Xundian County,Yunnan Province

以云南省寻甸县为例,运用空间自相关分析方法,研究8种土地利用类型在垂直方向上的分布特征。结果表明,8种土地利用类型在垂直尺度上都有较强的空间自相关性,在15个海拔梯度内分布不均匀,基本都是随着海拔的上升,数量先增加后逐渐减少,在15个海拔梯度内的土地利用结构存在差异。8种土地利用类型在垂直方向上呈现空间相关性,其中其他用地的空间自相关性最大,其次分别为园地、林地、工矿仓储用地、耕地、建设用地和水域及水利设施用地,草地空间自相关性最小。

Taking Xundian County of Yunnan Province as an example,and using the spatial autocorrelation analysis method,the ver⁃tical distribution characteristics of eight land use types were studied.The results showed that the eight land use types had strong spatial autocorrelation on the vertical scale,and the distribution was not uniform in the 15 elevation gradients.The number of land use types increased first and then decreased gradually with the elevation rising,and there were differences in the land use structure in the 15 ele⁃vation gradients.The eight land use types showed a spatial correlation in the vertical direction,and the spatial autocorrelation of other land use was the highest,followed by garden land,forest land,mining and storage land,farmland,construction land,water area and water conservancy facility land,and grassland had the lowest spatial autocorrelation.
