Preliminary Analysis of the Spatial Distributional Characteristics of Transmissibility Coefficient in Phreatic Water Aquifer

The research taking the shallow aquifer in Xinjiang Sangong river basin as the subject, applies the theory and method of geological statistics to analyze preliminarily the spatial distributional features of the transmissibility coefficient of the aquifer. The results shows that: 1, The spatial change of the transmissibility coefficient of aquifer complies with the normal probability distribution.2, The variability of the transmissibility is spatially moderate.3: To certain extent, the transmissibility coefficients are spatially correlated, the east-west correlating dimension is a =5.0 km and north-south a =7.8 km. 4, The water transmissibility of aquifer is anisotropic. The study methods and steps in this article can be used to analyze the spatial distributional features of transmissibility coefficient of the other alluvial-diluvial shallow aquifer.
