| 英文摘要 | Understanding the joint effects of earthquakes and driving factors on the spatial distribution of landslides is helpful for targeted disaster prevention and mitigation in earthquake-prone areas. By far, little work has been done on this issue. This study analyzed the co-seismic landslide of the M-s 8.0 Wenchuan earthquake in 2008 and 2014. The joint effects and spatiotemporal characteristics of the driving factors in seismic regions were revealed. Results show that (a) between 2008 and 2014, the dominant driving-factor for landslides has changed from earthquake to rock mass; (b) driving factors with weak driving force have a significant enhancement under the joint effects of other factors; (c) the joint effects of driving factors and earthquake decays with time. The study concluded that the strong vibration of the Wenchuan earthquake and the rock mass strength are the biggest contributors to the spatial distribution of landslides in 2008 and 2014, respectively. It means that the driving force of the earthquake is weaker than that of the rock mass after six years of the Wenchuan earthquake. Moreover, the landslide spatial distribution can be attributed to the joint effects of the Wenchuan earthquake and driving factors, and the earthquake has an enhanced effect on other factors. |
