| 摘 要： | 对江西省泰和县苏溪养分监测村的120hm^2的农田进行土壤采样，运用逆距离加权插值、田块平均值以及农田土壤养分空间变异插值模型对该区域的土壤样品进行插值分析，研究结果表明农田土壤养分空间变异插值模型较好地反映了土壤养分空间的分布。

| Abstract: | This paper analyzes the soil sample data by three mothods after they were collected from 120hm 2 of field in Suxi Mirror Village, Taihe County, Jiangxi Province, which were inverse distance weight interpolation, field average value and spatial variability interpolation model of field nutrients respectively. The results showed that the spatial variability interpolation model of field nutrients properly fitted the spatial distribution of soil nutrients. |
