PENG Zhi-liang1,ZHAO Ze-ying1,LI Zhong-yuan2,LI Li-jie1(1.Guizhou Institute of Agricultural Science and Technology Information,Guiyang,Guizhou 550006;2.College of Life Sciences,Guizhou University,Guiyang,Guizhou 550025,China)  
The spatial variability of Ca,Mg,S,B,Cu,Fe,Mn and Zn in soils of Limu village,Pingba county was analyzed and compared by the principal and method of classic statistic and geo-statistics,and GIS technology based on its measured data of soil nutrients.The distribution maps of their spatial variability were drawn by selecting optimum interpolation values according to their different spatial variability of nutrient elements in dry lands and paddy fields.
