地表水和地下水耦合模型研究进展

地表水和地下水的转换及其过程耦合模拟，是水资源开发利用和科学评价的基础。本文归纳了国内外16 种地表水和地下水耦合模型，并根据耦合模型的特点和耦合方式，划分了三类耦合类型，即：紧密耦合型、半松散耦 合型和松散耦合型。对其中比较典型的“四水”转化模型、SWATMOD、MIKE- SHE、MODBRANCH 模型进行了对比分 析，剖析了不同耦合模型的优缺点，为地表水和地下水耦合模拟研究提供了很好参考。

Advances in the Integrated Surface Water and Groundwater Model

With the effects of climate change and large-scale human activities,interactions between groundwater and surface water become more and more complex and acute.So studying groundwater and surface water as a whole system is urgent now.There are many integrated surface water and groundwater models,and they are divided into different kinds according to different standard.This paper summarized the existing 16 major integrated surface water and groundwater models at home and abroad,and classified them into close coupling and loose coupling.SWATMOD,MIKE-SHE and MODBRANCH model are described in detail on their functions,structures,coupling methods and deficiencies.At last,key problems to be addressed such as conversion of temporal or spatial scale,soil moisture movement in heterogeneous soil,parameter uncertainty,interactions between stream and ground water are pointed out,and the paper concluded that a complicated system model combining all the components in water cycle is the a trend of integrated models' development in present.
