| 摘 要： | 本文运用线性地质统计理论，确定研究区域的半变异函数二维平面结构为带状各向异性套合结构模型，给出土壤水分区域估值合理采样数，将Ｋｒｉｇｉｎｇ最优内插无偏估计法扩展为待估域的土壤水分含量外延估计，通过模糊聚类分析，绘制区域土壤水分含量的信息分布图，可为灌区水资源的计算机管理及灌区土壤水分监测预报提供依据。

| Abstract: | The linear geostatistics theory is applied to analyse the structure of the spatial variabiiity of the soil moisture and semi--variance function of the two--dimensional plan.The result indicates that the structure is a ribbon heterogeneous combination model and it gives the rational sampling number of the soil moisture regional estimation. Kriging optimum undeviation interpolation method is extended to estimate and calculate.Soil moisture information of the region by using grouping analysis, and drawing soil moisture information regional distribution map information expanded is established from point to region it provides the scientific basis for the district soil moisture and monitoring calculation.. |

| Keywords: | soil moisture spatial variability nested structure model estimation. |
