摘要:
西南山区是中国地质灾害链最发育、成灾最严重的地区。为深入认识区域地质灾害链成灾模式, 文章在系统收集西南山区历史上19次典型重大灾害事件基础上, 分析了地质灾害链的主控因素及成灾特征, 总结了滑坡型、崩塌型、泥石流型3类灾害链分类模式及5种链式成灾过程, 并选择每一类中的典型地质灾害链成灾过程进行了剖析, 在此基础上对地质灾害链成灾机理研究、数据库构建、技术标准体系建设及跨界流域链式灾害风险防控机制构建等进行了展望, 提出了地质灾害链防范建议, 旨在为区域地质灾害防灾减灾规划、重大工程与城镇建设安全提供参考。
Abstract:The southwest mountainous region in China is the worst-hit area due to the most developed geohazard chains. In order to better understand the pattern of the geohazard chains in this region, we analyzed the main control factors and characteristics of the geohazard chains based on 19 typical geohazard events in history. Three classification patterns, namely landslide-type, collapse-type, debris flow-type, and five typical hazard-inducing processes, were summarized. A typical hazard-inducing chain process in each model was selected for analysis. On this basis, we discussed the mechanism of the geohazard chain, the construction of a database and technical standard system, and the measures for preventing and controlling transboundary basin chain-type geohazards, aiming to provide a reference for the regional geohazard prevention and mitigation plan, and the major engineering projects' construction and people's safety in town.
