摘　　要：随着计算机及3S技术的发展,越来越多的开发平台和语言开始出现,软件编码的冗余和不兼容成了制约信息产业发展的瓶颈。模型驱动理论框架(MDA)运用统一建模语言(UML),致力于设计一种开放的模型框架来实现各种软件及开发语言的共享和互操作。本研究正是在统一的数据标准体系和信息编码体系支持下,对基于3S技术和三维模拟技术的城市地质灾害进行分析、评价与预测,并进一步分析类的属性、行为及相互关系,采用UML语言建立起城市地质防灾领域的概念模型,为地质防灾应急系统的开发提供快速高效的模型基础,实现对地质灾害的预警和决策知识支持。With the development of 3S and information technology, more and more programming languages and platfomas have rushed, which mainly leads to the incompatible and redundant between software. Model driven architecture （MDA） has tried to give a way to share the programmers＇ diligent work,and unified modeling language （UML） is used to standardize the process of software development. With the base of unified data criterion architecture and information code architecture, the geologic hazards are analyzed and geologic information rnodds are preliminarily designed in this paper. By efficiently and visually analyzing and processing of geologic information with spatial distribution characteristics, the system are validated with good prediction and preparedness of geologic hazards.
