青藏高原东南缘活动断裂地质灾害效应研究现状

青藏高原东南缘不同性质、不同类型、不同特点活动断裂发育且较为活跃，自2008年汶川地震发生以来，相继发生了玉树地震、庐山地震、鲁甸地震等。地震引发、触发、诱发产生了大量地质灾害，造成了惨重的生命财产损失。通过收集与分析相关资料，对青藏高原东南缘活动断裂地质灾害效应研究进展与取得成果进行了归纳总结，从活动断裂地质灾害主要控制因素，地质灾害发育特征、空间分布规律、演化模式、形成机制，不同性质断裂控制效应、断裂两盘差异效应、地震动参数效应、地形地貌效应等地质环境效应和地质灾害力学效应等方面进行了综述。在此基础上，对活动断裂地质灾害效应研究中存在的如不同类型活动断裂和不同震级地震与地震地质灾害相关性、以及地震地质灾害监测与风险评估等问题或重点研究方向进行了探讨，其研究结果为地震地质灾害致灾机理、风险评估、防灾减灾等研究提供参考。 

ADVANCES IN RESEARCH ON THE GEOHAZARD EFFECT OF ACTIVE FAULTS ON THE SOUTHEASTERN MARGIN OF THE TIBETAN PLATEAU

Active faults of different properties, types and characteristics, developing on the southeastern margin of the Tibetan Plateau, are relatively active. Since the Wenchuan earthquake in 2008, there have occurred several earthquakes, including the Yushu earthquake, Lushan earthquake, Ludian earthquake and other earthquakes, which induced a large number of geological disasters and leaded to catastrophic losses of life and property. Based on data collection and analysis, advances in the earthquake geohazard on the southeastern margin of the Tibetan Plateau are summarized. Geohazard effect of active faults including the main control factors of geological disaster, spatial distribution regularity, evolution pattern and formation mechanism, the geological environment effect such as active faults with different properties, the difference between two plates, ground motion parameters and topography, and mechanical effects of geological hazards are analyzed. Then the main problems or key research directions in the study of the geological disaster effect of active faults, such as the correlation between the active faults with different properties, the earthquake with magnitude and geological disasters, and the seismic geological disaster monitoring and risk assessment, are put forward. The results can provide strong support for the study of the mechanism, risk assessment, disaster prevention and reduction of seismic geological disasters.
