区域滑坡泥石流触发响应机制及灾害防治启示——以甘肃中南部地区为例

Regional Trigger-Response Mechanism of Landslide-Debris Flow and the Significance of Hazards Control——Taking Mid-southern Gansu as Example

以甘肃中南部地区为例,分析讨论了触发响应机制与区域滑坡泥石流活动关系,总结了有关研究进展.进一步论述了触发响应机制控制的区域滑坡泥石流活动特征.基于触发响应机制与致灾机制关系,划分了甘肃中南部滑坡泥石流触发响应类型区,最后提出相应灾害防治启示.

Taking the mid-southern Gansu as our study areas, we have first analysed the relation between of regional trigger-response mechanism and landslide-debris flow activity in magnitude, then summarized the advances of related research, and discussed the regional characteristics of landslide-debris flow activity, and finally presented landslide-debris flow pattern controlled by the trigger-response mechanism in mid-southern Gansu and stated the significance of hazards control.
