摘　　要：UCODE是美国地质调查局(USGS)为地下水模型逆问题求解开发出的一套通用求解程序,可以与各种过程模型(有限元femwater或有限差modflow等等)耦合使用。它采用修正的Gauss-Newton法对逆问题进行求解,并在求解过程中引入摄动敏感度,同时master-slave协议的加入为程序提供了卓越的并行计算能力。该文简单介绍UCODE程序的功能及使用,并结合具体算例讨论UCODE在反求水文地质参数中的应用。UCODE is a set of common solving program developed by the United States Geological Survey for solving inverse problems in groundwater model,it can couple with kinds of process models（femwater of FEM or modflow of finite difference etc.）.The inverse problem is solving with the modified Gauss-Newton method,and the perturbation sensitivity is introduced in the solving process,while the master-slave protocol provides an excellent parallel computing capacity.This article briefly describes the capabilities of UCODE program,and discusses the application of UCODE to calculation for hydrogeological parameters combined with specific examples.
