摘要
黄土受自身结构属性影响,在自然或人为外力的作用下易诱发滑坡灾害。据统计,中国至少有1/3的滑坡灾害发生在黄土高原,滑坡发育密度已经高达每平方千米6个,每年新增滑坡灾害百余起。黄土滑坡已成为黄土高原最具代表性的地质灾害。从黄土的基本属性入手,通过拟人表述,重点介绍了黄土滑坡的自然与人为诱因,并对黄土滑坡与人类的协调方式进行讨论,以期能让大众了解黄土滑坡灾害,提高灾害防控意识。
Loess is influenced by its own structural properties and easily caused landslide disasters under the natural or artificial forces.According to the statistics,1/3 of the landslides in China occurred in the Loess Plateau with a density of 6 per square kilometer,more than 100 new landslides occur annually.It’s conceivable that loess landslide become the most representative geological hazard in the Loess Plateau.This paper introduced basic properties of loess,focused on natural and artificial inducing factors of loess landslide,and discussed the harmonious way between human and loess landslide,with a view to let the public understand the loess landslide disaster and strengthen awareness of disaster prevention and control.
