中文摘要：

2008 年 5 月 12 日 Mw 7.9 Wenchuan，中国地震触发了大约 200,000 山崩，它被很多个因素控制。这研究检验五个因素：斜坡角度，斜坡方面，岩性学，山峰地面加速(针网阵列)，和差错站在一起( seismogenic 差错上的相对位置，即，挂的墙或矿脉基卒下盘)，决定这些因素怎么并且是否控制co地震的山崩出现至少一个因素，独自或在音乐会行动，涉及支持或压制山崩。我们执行了一个多因素用从 2008 Wenchuan 地震的数据的统计分析。结果在陡峭的地形学描绘的区域显示出那或在充分的理由摇晃发生在地震期间的地方，比另外的区域在斜坡方面和山崩数字密度(LND ) 之间有一种更靠近的关系。在岩性学和 LND 价值之间的关系取决于针网阵列。接着，在 LND 价值和针网阵列之间的关系被岩性学也影响。另外， seismogenic 差错的挂的墙上的 co 地震的山崩上的岩性学的控制效果在矿脉基卒下盘上比那大。在这些因素之中检验相互作用能改进 co 地震的山崩出现的机制的理解。

英文摘要：

The 12 May 2008 Mw 7.9 Wenchuan, China earthquake triggered about 200,000 landslides, which were controlled by a number of factors. This study examines five factors： slope angle, slope aspect, lithology, peak ground acceleration （PGA）, and fault side （relative position on the seismogenic fault, i.e., hanging wall or footwall）, to determine how these factors control the co-seismic land- slide occurrence and whether one or more factors, acting alone or in concert, are involved in promoting or suppressing landslides. We performed a multi-factor statistical analysis using data from the 2008 Wenchuan earthquake. The results show that in the areas characterized by steep topography or where strong ground shaking occurred during the earthquake, there is a closer relation- ship between slope aspect and landslide number density （LND） than other areas. The relationship between lithology and LND values depends on PGA. In turn, the relationship between LND values and PGA is also influenced by lithology. In addition, the controlling effect of lithology on co-seismic landslides on the hanging wall of the seismogenic fault is greater than that on the footwall. Examining interactions among these factors can improve understanding of the mechanisms of co-seismic landslide occurrence.
