中文摘要: 台风的特大暴雨可以引发山体滑坡和泥石流等地质灾害，造成严重的人员伤亡。高分辨率资
料的应用是地质灾害精细化预报的基础。选定频繁遭受台风袭击，同时受地质灾害影响严重
的浙江乐清市作为研究区域，利用雷达联合雨量计估计降雨技术，以0414台风云娜、0505台
风海棠和0509台风麦莎导致的群发性地质灾害为例，研究雷达估计降雨在监测地质灾害方面
的适用性以及台风降雨和地质灾害发生之间的关系。结果表明，雷达估测降雨较好地反映地
质灾害触发雨量特征。台风诱发地质灾害需要的持续时间短，有效雨量更小，临界雨强大。
Abstract:Typhoon rainstorm can induce geological hazards such as landslides and
debris flows and cause serious casualties consequently. High resolution data a
re essential for high resolution geological hazard prediction. Yueqing in Zhejia
ng Province is selected as the studied area, which is frequently attacked by typh
oons and is seriously influenced by geological hazards. Geological hazards induc
ed by typhoon No.0414, No.0505 and No.0509 are taken as samples. Applicabilit
y of radar rainfall estimation is assessed for the studied area. Relations betwe
en typhoon rainstorms and geological hazard occurrences are carefully studied by
use of radar raingauge rainfall estimation. The results show that the radar ra
infall estimation can reflect the characteristics of triggering rainfall of geolo
gical hazards in great details. Typhoon induced geological hazards need shorter
rainfall duration, smaller effective rainfall, but higher critical rainfall inte
nsity.
