摘要:
孙水河流域地质环境条件复杂,人类工程活动强烈,崩塌、滑坡、泥石流等地质灾害发育,水土流失问题严重,地质灾害在形成与发展演化过程中呈现出明显的链式效应。采用野外调查、遥感解译和综合分析相结合方法,查明了孙水河流域地质灾害链的主要诱发因素:强降雨、人类工程活动及其共同作用; 基于灾害链激发环、灾害链演化环、灾害链损害环分别论述了孙水河流域境内强降雨、人类工程活动及两者共同作用下诱发地质灾害链的类型结构和成灾特征; 从监测预警网络建设、防灾减灾体系完善、地质灾害综合治理实施以及地质环境保护和植被恢复推进等方面,提出了孙水河流域地质灾害链的断链对策。
Abstract:
Sunshui River is located at the left bank of Anning River. Affected by the special geological, geomorphological conditions and intensive human activities, geological hazards, such as landslides and debris flows, are widely formed in the Sunshui River drainage. What's more, the evolution of geological hazards takes on an obvious characteristic of chain effect. In this paper, based on field investigation, RS interpretation and comprehensive analysis, the triggering factors of geo-hazard chains were found out. According to the triggering link, evolution link and damaging link, the structure types of geo-hazard chains in the Sunshui River drainage are classified and the corresponding disaster characteristics are summarized systematically. In the end of this paper, chain interuption countermeasures were put forward for disaster mitigation, drainage development and geo-environment protection.
