21世纪全球环境问题将更加突出，环境地学应为研究、解决环境问题做出更多的贡献。但是，环境地学研究所采用的方法和手段还不能满足客观的需要。文章着重讨论了环境模拟系统(Environmental Imitation System,EIS)的建立及EIS与地理信息系统(Geographical Information System,GIS)的耦合等问题。作者通过研究，认为上述问题已基本得到解决．从而可以弥补GIS中环境模拟功能的不足，可使EIS纳入GIS的信息空间管理系统，进行信息空间管理、应用分析和信息叠加，并使信息可视化。文章最后指出．目前，可建立GIS-EIS联合系统，以实现信息互换和信息资源的二次开发、利用。%Environmental problems will be more serious in the world in the 21st century, so environmental geology should make more contribution to study and resolving of these problems. However, the methods and instruments that are used on environmental geology do not satisfy external need. This paper discusses some problems about establishing EIS (Environmental Imitation System) and coupling GIS (Geographical Information System) with EIS. Through research, the authors suggest that these problems have been resolved basically. The coupling technology could remedy some defects of the function of environmental imitation in GIS and make EIS into space management system of information in which space information are managed, appliance analyzed and spliced, and made videotex. In the end, the paper indicates that co-system of GIS and EIS can be established to accomplish interchange, second developing and using of information.
