摘　　要：滑坡灾害是危害最为严重的地质灾害之一,防治这种地质灾害最有效的途径是对其进行预测预报。为了较好地预测预报滑坡灾害,通过对滑坡灾害危险等级区划模型进行深入研究分析,采用滑坡有效降水引发的滑坡灾害危险区划模型,运用GIS二次开发方式设计实现了区县级精细化滑坡预测预报系统,完成了滑坡灾害危险等级区划结果预测及滑坡灾害信息管理。该系统以文本、图片的方式,通过电视、广播、互联网、远程Web访问、手机短信服务等多种渠道向公众发布当日及未来3日可能发生危险滑坡等级,提供应对措施等有效参考信息,也为当地政府部门制订防灾、减灾措施等提供科学的决策依据。Landslide is one of the most serious geological disasters, and the most effective way to prevent landslide disaster is forecast. In this paper, landslide disaster regionaIization model induced effective precipitation is used in analyzing in-depth landslide disaster risk rating regionalization models, and implemented landslide disaster refinement forecast system in district level based on GIS secondary development approach. The main function of system is to achieve the result of landslide disaster risk rating forecast and landslide disaster information management. The forecasting results obtained by the system can provide a scientific basis for the local government departments such as planning measures on prevention and mitigation disaster. While the forecasting results are also published to the public, which can help the public take response timely and reduce losses.
