三湖河灌域富水岩层顶板及含水层底板高程的*估值研究

Estimation of plentiful water aquifer elevation in Sanhuhe irrigation field

【目的】运用地质统计学理论,对三湖河灌域的富水岩层顶板及含水层底板高程进行空间变异性分析。【方法】在实测36个已知信息点的基础上,运用普通克立格法(OK法)对未知点处的富水岩层顶板及含水层底板高程进行估值。【结果】在已知信息值和估计值的基础上,绘制了研究区富水岩层顶板与含水层底板高程空间三维分布图。【结论】将地质统计学理论运用到水文地质领域,对三湖河灌域未知点处的富水岩层顶板及含水层底板高程进行估值,可以弥补由于采样困难而引起的实测数据不足的弊端。

[Objective] The spatial variability of plentiful water aquifer top layer and aquifer floor elevation in Sanhuhe irrigation field is researched using the Geostatistics. [Method] On the basis of 36 known information points,plentiful water aquifer top layer and aquifer floor elevation of unknown points are estimated using Ordinary Kriging （OK） method. [Result] Based on the known and unknown information points, three-dimensional space distribution maps of plentiful water aquifer top layer and aquifer floor elevation are drawn. [Conclusion] Geostatistics is used to simulate and predict the stratigraphic data,and absent data can be covered.
