CGE模型在水资源研究中的应用与展望

文章简要介绍了CGE模型及其在水资源研究中的应用，归纳了水资源在模型中的处理方法，分析了CGE模型应用于水资源研究中存在的问题，并对未来发展趋势进行了展望。从处理水资源问题的方法看，约束条件、要素、中间投入和综合处理等4 种方法是主要的建模手段，并随着数据和建模技术的发展，模型向精细化、复杂化和贴近实际发展。尽管CGE模型在水资源研究中的应用仍然受制于模型本身的缺陷以及对水资源问题的认识和处理方式，但随着理论发展、数据完善，CGE模型在水资源研究中的应用会逐步朝着标准化、模块化、精细化和实用化的方向发展。

Application and Outlook of CGE Model in Water Resources

CGE model and its applications in water resources are briefly introduced in this article.The approaches to integrate water resources in CGE model and problems and outlooks forthe CGE model application in water resources are discussed. Four approaches to integrate waterresources in CGE model are widely used, including constraints, elements, intermediate inputsand comprehensive treatment. With the improvement of data and modeling techniques,more and more detailed, complicated and practical models have been developed. Although theapplication of CGE model in water resources is still subject to modeling defects and the understandingof the water resources issues and its treatment, with the theoretical development anddata collection, CGE model applications in water resources will gradually develop toward standardization,modularization, as well as being more sophisticated and practical.
