【摘要】 针对当前黄土高原土壤侵蚀预测预报研究存在模型计算繁琐、模型与GIS耦合松散的不足,提出开发黄土高原土壤侵蚀预报信息系统的思路.首先,在综合分析系统需求的基础上,进行系统的总体设计,选定开发平台,完成了系统的总体逻辑框架;其次,根据系统的数据内容,结合GeoDatabase数据模型,给出了系统数据库设计原则并进行系统数据库设计;最后,从基础数据组织、空间分析、预报模型与GIS功能耦合三方面进行探讨,提出了相应的解决方案,最终实现了黄土高原土壤侵蚀预报信息系统.更多还原

【Abstract】 According to the current lack of the research on soil erosion prediction of the Loess Plateau,the development of the soil erosion prediction information system on Loess Plateau is proposed.Firstly,this paper presents the global design,specifies the development platform,and bring forward the overall logical framework of the system on the basis of the comprehensive analysis of the system requirement.Secondly,according to the geodatabase data model,the thesis points out the principles of database design,and fulfils the database design of the system.Finally,the paper discussed the organization of the fundamental data,spatial analysis and the forecasting model coupled with GIS in detail,bring forward the corresponding solution,and realized the soil erosion prediction information system on Loess Plateau at last.更多还原
