摘要
滑坡灾害链式阶段特征具有直观、形象、特征鲜明的特点,也是把握链式演变规律的关键。本文对滑坡灾害链式特征进行概化,对链式发育阶段进行划分,并将滑坡灾害演绎规律用链式关系予以表征,在充分把握各链式阶段特性基础上提出实施断链减灾的调控,大大提高控制灾害发育和蔓延的有效性;对滑坡灾害处于弱势环境断链减灾,将能抵御滑坡灾害对人类的威胁,具有防灾的可能性和重大意义。
The slope disaster chain-stage characteristics are intuitionistic,visual and vivid,and it is the key of understanding the chain evolvement rules.This paper summary of the slope disasters chain-styled characteristic,and divide the chain-styled developmental stage＇s.The principle and evolutive law of slope disasters are expressed by chain-styled relation,so that chain-cutting disaster reduction can be pertinently controlled based on adequately grasp of the characteristic of each chain-styled stage;When the slope disasters are in the weak environment,we carry out chain-cutting disaster mitigation which will be able to resist the disaster evil to threaten the human,and have possibility and great significance of disaster prevention.
