强降雨诱发地质灾害气象预警指标及应用研究

The meteorological early warning index for geological disaster caused by heavy rain and its application

通过对浦北县境内2006—2013年期间不同强降水天气过程有效降雨量累计与地质灾害发生情况分析,结合县域地形、地貌等地质环境,分区域建立了强降雨诱发地质灾害的预警指标体系,经过2014-2015年强降雨诱发地质灾害气象预警服务检验,结果与实况基本相符。这一结果对今后开展地质灾害气象监测预警服务有重要意义。

Based on the analysis of geological disaster and accumulating effective rainfall of different strong precipitation weather processes during 2006 to 2013 in Pubei county of Guangxi and combined with the geological conditions, the early warning indexes of heavy rainfall causing geological disaster were established. After the test of weather warning service condition during 2014 to 2015, the results were consistent with the fact. This result has significant meaning to the future development of geological disaster weather monitoring and warning services.
