地下水动态观测网优化设计研究

本文采用状态空间分析法,通过对地下水流系统输入变量、输出变量及地下水动态测量值的研究,提出了地下水流系统确定一随机性数值模型。运用该模型的模拟解,进行地下水动态观测网优化设计。该方法把地下水动态观测网密度、位置及观测频率优化与地下水流系统结合起来研究。为了克服该模型计算量大的缺陷,本文提出了一种改进算法,使这一观测网优化方法适于在微机上实现,减少了计算工作量。该方法曾用于陕西某地区地下水位动态观测网的优化设计,取得了显著经济效益。

A STUDY ON OPTIMAL DESIGN FOR GROUND WATER REGIME OBSERVATION NETWORK

Using the method of state spatial analysis,in the paper is presented the deterministic.stochastic numerical model of groundwater flow system through the input,out-put variables and measurement of groundwater regime. The simulation solution of the model is applied to optimal design of groundwater regime observation network. The method combines the density ,abservation frequency of groundwater regime observation network with groundwater flow system. In order to overcome the deficience that computation occupies large-memory of computer,in the paper is proposed a modified algorithm applied to computation in microcomputer ,and the time of computation is largly decreased. The method is applied to optimal design of groundwater level regime observation network at some site in Shaanxi province. It turns out that economic efficiency is increased largly.
