中国灾害暴雨泥石流预报分区研究

Study on the debris flows forecast and its divisions formed by disasters rainstorm in China

本文采用多因素相似组合分区原则,对我国灾害暴雨泥石流进行了小比例尺的预报分区。文中综合考虑了泥石流分布、活动特点与地形、地质构造因素的关系,泥石流发生与气候、气象和降水的关系,提出了灾害暴雨泥石流各个分区预报的季节、天气尺度系统、日降雨量和小时雨量强度指标,并对各个分区做了简述。

According to the principle of multi-factors classification,China was divided into four sections to forecast debris flows from calamitous rainstorm.The debris flow was predicted in these regions according to elationships between topographical/geological structure,debris flows distribution,rainfall during certain period,and the general characteris- tic of the climate.A breif instruction was also given to each division.
