摘要： 本文从水文地质的基本原理出发,从几个不同的侧面导出了地下水系统状态转移方程的一般形式。以山西省太原市3个地下水源地为例,用长系列观测资料对地下水系统进行了过程辨识。

关键词: 过程辨识, 区域地下水系统

Abstract: A state-space model is presented for analysing and formulating groundwater system in this paper.From several models of groundwater system, such as ideal analytical model, numerical model, statistical model, response function model, and based on the principle of water balance and Darcy's Law, a general dynamic equation of groundwater system is deduced and established. Physical and test approaches are summarized as two main identification means of groundwater system and their advantages are analysed respectively.Taking 3 groundwater sites in Taiyuan, Shannxi province as an example, the model parameters of the groundwater system have been identified with long-series observed data of input and output.

Key words: process identification, regional groundwater system
