摘　　要：本文介绍了湖南地质灾害概况,通过对暴雨诱发地质灾害的机理分析和多普勒雷达系统监测暴雨的可能性分析,选取地质灾害频发的湖南省作为典型研究区,通过多普勒雷达图像地质灾害气象反演分析和灾害识别研究,精确地预报了湖南省新邵县"2005-05-31"特大地质灾害,论证多普勒雷达是监测突发性地质灾害的有效手段。Hunan is one of the provinces in China suffering from serious geological hazards with many types and extensive distribution. Heavy rain and continuing rainfall are the main contributing factors to geological hazard. This thesis analyzes the situation of geological hazard meteorological forecasting and alarming based on the occurrence of geo-hazard to the weather which combines the geo-environmental conditions in Hunan Province. Taking the example of Xinshao County on 31, May 2005, the retrieval technique and forms the forecasting method of geo-hazard by Doppler Weather Radar is studied. The Weather Radar image was applied to forecast the geo-hazard and the results proved the method to be practicable and precise.
