| 摘 要： | 根据浙江省降雨的特点,将降雨分为台风降雨和非台风降雨,采用统计方法研究了区域性滑坡灾害与台风区和非台风区降雨量及降雨强度的相关性,通过相关性分析确定了有效降雨量模型;得到了浙江省区域性滑坡发生的临界降雨量和降雨强度阀值,为实时时间预警提供了定量依据;将滑坡灾害的空间易发性与降雨量和降雨强度相结合确定了滑坡灾害的空间预警区划指标和等级;最后初步研究了滑坡发生的滞后时间。

| Abstract: | Based on the characteristics of rainfall in Zhejiang Province,the authors divide rainfalls into typhoon rainfall and non-typhoon rainfall,and study,with the statistic method the correlation of regional landslide hazards and typhoon and non-typhoon rainfall and rainfall intensity.The effective rainfall model is defined by correlation analysis,and the threshold valves of critical rainfall and critical rainfall intensity are obtained to predict the time quantitatively.The indexes and grades of spatial early-warning are taken by the analysis of the easiness of landslide hazards and rainfall and rainfall intensity.In the end,it discusses the lagged time of landslides. |
