| 摘 要： | 利用山西省地质环境中心提供的1956-2004年间32个区划县由气象因素诱发的354例地质灾害和山西省气候中心提供的与354例突发性地质灾害相对应的当天、前14天逐日24 h的降水量等资料,分析了地质灾害发生的时空分布特征及降水量、降水强度、降水持续时间、降水累积量与突发性地质灾害的关系,结果表明：气象因素诱发的地质灾害以滑坡为主。地质灾害东部多于西部、山区多于平川,集中发生在6-9月。日降水量〉50 mm时,发生滑坡的概率为65.5%;连续15天累积雨量〉100 mm时,发生滑坡的概率为81.3%。此外,分析地质灾害与影响天气系统关系发现：副高西进北抬往往导致单发性地质灾害,东退南压则往往导致群发性地质灾害;地质灾害发生在副高外围5840和5880 gpm线之间的区域。

| Abstract: | Based on 354 geological disaster events induced by meteorological factor from Shanxi province geological environment center and the corresponding meteorological data from Shanxi province climate center(including 24 hour rainfall in the days of events and in 14 days before the events,etc) located in 32 counties of Shanxi province from 1956 to 2004,analyze the temporal and spatial distribution characteristics of geological disasters and the relationship between meteorological condition(such as rainfall,the pr... |
