以长沙市为例，采用2013年野外采样室内实验所得数据，运用 ArcGIS 地统计分析模块，利用克里金插值分析其土壤全磷空间分布规律，对长沙市农田利用与管理具有积极意义.结果表明：（1）土壤全磷最优插值模型为 Tetrasphercial 模型，其 C0/（C0＋C）值为4.23％，表现出强烈的空间相关性；（2）在空间上，土壤全磷大致是由东向西逐渐降低；（3）土壤全磷分布在2~5级，且以2级和3级为主.

By the method of Kriging,the spatial variability of soil total P of Changsha city based on the data of the field sampling and income laboratory experiments in 2013 was analyzed with ArcGIS geo-statistical analyst,so as to provide guidance for soil fertilization management and agricultural production.The results showed that：（1）the optimal interpolation models of soil to-tal P was best described with a tetrasphercial model with ratio of nugget to sill of total P was 4.23%,indicating that the spatial correlation of the total P was intensely spatially dependent.（2）in spatial variability,the total P distribution was generally de-creased from east to west.（3）the soil total P was mainly distributed in the grade of 2-5,and give priority to in order to grade 2 and 3.
