给水度的空间变异性及其估计和预测

Spatial Variability of Specific Yield and Its Estimation and Prediction

文中运用地质数学中平稳区域化变量的理论,对研究区内潜水变幅带给水度μ进行了结构分析,找出了它的主变异方向和变异程度,并应用普通克立格法对给水度μ进行了最优估计和外推预测,进而给出了它的空间变异分布图和参数分区图。

Structural analysis of specific yield (μ) in the fluctuation belt of phreatic water within the researched area was made and both the main direction and range of its variance were acquired by using the steady regionalized variable theory of geostatistics herein. Optimum estimation and external interpolation of (μ) were conducted by kriging and spatial variability maps and parameter distribution maps were also proposed.
