云南省地质灾害预报预警系统

PREDICTION SYSTEM OF GEOLOGICAL HAZARD IN YUNNAN PROVINCE

基于云南省地质灾害综合研究成果,架构云南省地质灾害预报预警模型方法,认为:影响地质灾害活动是多种因素叠加,地质灾害系统是一个开放、复杂的灾害系统。在对影响地质灾害发生因素分析的基础上,可以利用相应的预测模型,对给定区域内发生地质灾害的危险度作预测,由此创建概念模型和数学模型,运用VB语言在M apG IS平台上进行二次开发,建立了云南省地质灾害预报预警系统。

A modeling method for geo-hazard prediction in Yunnan Province is put forward according to the comprehensive study on the geo-hazard in Yunnan. We think that the geo-hazard is an open and complicated system, which results from the superimposition of multifactor. Based upon an analysis of the factors of geo-hazard, we can predict the risk level of the geo - hazard in a certain area by a correlative prediction model and then set up the conceptual model and mathematical model. And the prediction system of geo-hazard in Yunnan Province is set up by the re-development on the MapGIS using VB language.
