摘　　要：王涛等"基于简化Newmark位移模型的区域地震滑坡危险性快速评估——以汶川M S8.0级地震为例"一文的地震滑坡危险性快速评价结果与2008年汶川地震触发实际滑坡空间分布的相关性较低。本文试图通过对该文中基础数据、分析处理过程、研究结果的分析与讨论,找出这种相关性较低的原因。结果表明值得针对王涛等文章中的Arias烈度分布数据的准确性、工程地质岩组的划分情况、汶川地震滑坡危险性评价结果的客观性共三个方面开展更深入的分析与研究。本文对探索与发掘更客观的地震滑坡危险性评价模型起到了积极的作用。A relatively low correlation appeared between the result from the published paper of Wang Tao et al. named Case study on rapid assessment of regional seismic landslide hazard based on simplified Newmark displace- ment model： Wenchuan Ms8.0 earthquake＂ and spatial distribution pattern of actual landslides triggered by the 2008 Wenchuan earthquake. The main purpose of this comment or discussion is to analyze the reasons of the low correlation by analyzing and discussing of basic data, data analysis process, and results from that paper from Wang Tao and his research teams. The results suggest that Wang Tao and his teams carry out a more in-depth study in three aspects, include accuracy of the Arias intensity data, engineering geology lithology formation groupings, and validation of the Wenchuan earthquake-triggered landslides hazard assessment. This comment plays a positive role on exploring more scientific landslide hazard assessment models.
