摘要
根据东川区泥石流的成因、泥石流灾害信息源、各类数据的表达方式及泥石流信息系统的应用等,对东川区泥石流信息系统进行了系统分析,在此基础上利用3S技术,在ARCVIEW的AVENUE开发语言支持下,集成各类数据,建立东川区泥石流信息系统,最后讨论了该系统在泥石流危险度区划及灾害趋势分析中的应用。
This paper considers the construction and application of a debris flow information system for Dongchuan District,Kunming City.System analysis is done from the following five aspects:reasons of Debris Flow formation,hazards information sources,expression of data,and main application fields and instance of Dongchuan District.Basing on the system analysis,supporting by AVENUE language of ARCVIEW,the3S technology is used to establish Debris Flow Information System of the study area.The functional modules of the system mainly include database management (data input,modification,display and query)and mathematic models.Lastly,the system is applied in the real work of debris flow disaster mitigation such as dangerous degree zoning,development analysis,and comprehensive disaster prevention and control.
