Spatial Variability of the Farmland Organic Matters and Macroelements in Linyi County

Based on the soil sample of the Linyi county and GS+ software,the spatial variation characteristics of the soil nutrients were studied.The geographical statistical method was carried on the analysis to spatial variation of the soil organic matters and macroelements.Result indicated that the soil organic matters and total nitrogen had small variation degree,the rapidly available potassium taking the second place,the available phosphorus showing the biggest variation,they all belonged to the medium variation;The spatial variation of the soil organic matter,total nitrogen and rapidly available potassium mainly caused by the area factor,and the spatial distribution manifests for the medium spatial relativity.The spatial variation of the available phosphorus fiercely caused by the stochastic factor,and spatial distribution manifests for the weak spatial relativity.
