【摘要】 以内蒙古鄂尔多斯荒漠草地小尺度(20 m×20 m)土壤水分、EC、全氮含量及地上植被干物质量为研究对象,运用地质统计学方法,从统计特征、合理采样数、变异函数等方面分析了土壤特性与植被的空间变异性,认为其均呈近似正态分布并具有中等强度的空间自相关性。初步揭示了该区域土壤、植被的空间结构变化,对干旱草地水土保持与荒漠化治理具有指导意义。更多还原

【Abstract】 The authors studied the spatial variability of the water,EC and nitrogen in soil and the dry substance of vegetation on a little scale in Erdos desert grassland.Based on the analysis of statistic,logical hits and variogram,analyzed the variability of soil and vegetation.It is considered that the distribution of them are all approximate normal school,and they all have medium spatial self-relativity.The elementary conclusions discovered spatial structure of soil and vegetation in this region,it is important for soil and water conservation and fathering desert in droughty grassland.更多还原
