【摘要】 牧区防旱减灾辅助决策系统是地理信息系统、网络技术、数据库技术、面向对象的编程技术等现代计算机技术与牧区防旱减灾理论和技术相结合发展起来的专业应用信息系统，是水资源信息系统的有机组成部分。它通过对旱灾发展行为的模拟、旱灾损失的评估，以及防旱减灾水资源调配等工作，为防旱减灾提供科学的参考依据，辅助防旱减灾决策部门进行决策。目前在我国的水资源信息系统建设中，关于牧区防旱减灾信息系统的建设还处在薄弱环节。本人结合国家西北水资源数据库项目和呼和浩特市地理信息系统项目，利用GeoMedia Professional的新技术，以及它提供的GeoMedia组件，使用面向对象的开发方法，初步开发出了客户机／服务器结构的牧区防旱减灾辅助决策信息系统。 本文简要介绍了我国牧区基本的自然经济概况、干旱情况以及干旱灾害对牧区经济和草原生态造成的危害，建立防旱减灾辅助决策系统的理论基础；对旱灾的研究现状进行了分析，展望了防旱减灾辅助决策的发展前景；重点研究了旱灾区域选择、旱灾行为模拟、旱灾损失评估以及最佳水资源调配方案的设计与实现；分析了GIS空间数据库管理以及图形用户界面设计等较为关键的应用技术；并以内蒙古四子王旗牧业县作为案例，对系统进行了实验验证。最后指出辅助决策系统必将在牧区的防旱减灾中发挥重要的作用，从而为牧区经济发展和生态环境建设提供服务。更多还原

【Abstract】 Drought Relief Assistant Decision System is the professional application that is developed through the integration of drought Technology, Geographical Information System, Network Technology, Database Technology and Orient Object Program Technology and so on. It is the organic component of Water Resources Information system. It provides scientific reference and assists Drought Department to make decision by drought tendency simulation, drought loss estimation and drought relief and so on .While Drought Relief Assistant Decision System is still the weak link in the building of water resources Information System in our country. Combining with the Water resources Database Project of Northwest region , Water resources GIS Project of huh. region , the author used the newest technology GeoMedia Professional, the secondary programming tools Geomedia , the method oriented object and developed c/s-based drought relief assistant decision GIS system.This paper briefly introduced the situation of physical geography ,economy and environment, and the influence of drought for pastoral area .The Drought Relief Assistant Decision system developing background , theory foundation latest development in the world; Put emphasis on the realization of the several key models such as drought region selection ,drought tendency simulation ,drought loss estimation and the drought relief; Analysis the key application technique of GIS spatial database management and graphical user interface in the process of building the system ; To test the validity of Assistant decision system., take the area of SiZiWang Countyjnner Mongolia as an example .In the end pointed out that drought assistant decision system would play more and more important role in the work of drought fight, informing reference for economic development and environment build.更多还原
