一、引言人类在其生存环境中面对着许多危险,其中地质灾害是主要的一部分。这类地质灾害主要涉及自然环境中的突发事故,通常与景观中大规模块体运动有关。为了了解这类自然灾害的性质,必须了解景观演化的过程:地质灾变不是别的,只不过是在景观自然演化过程中极为有害的“几步”。众所周知,景观演化遵循比较少的几条基本原则。景观演化的第一条基本原则是指这一显而易见的事实,即景观表示在两个对立过程——构造(内因)抬开和外力(外因)剥蚀——的相互
I. INTRODUCTION Humans face many dangers in their living environment, of which geological disasters are the main part. This kind of geological disaster mainly involves sudden accidents in the natural environment and is usually related to large-scale block movements in the landscape. In order to understand the nature of such natural disasters, it is necessary to understand the process of landscape evolution: Geological catastrophes are nothing more than just “a few steps” that are extremely harmful in the natural evolution of landscapes. As we all know, landscape evolution follows a few basic principles. The first basic principle of landscape evolution refers to the obvious fact that the landscape is represented in two opposing processes—the mutuality of structural (internal) elevation and external (external) erosion.
