摘要
我国疆域辽阔,地形地貌多样,但也是地质灾害频发的国家之一。进入21世纪以来,随着全球气候的变化,我国地质灾害事件接连发生,加之社会发展进程中人类经济活动的不断增加,使地质灾害的发生频率不断增长,造成的人员伤亡和经济损失呈逐渐上升趋势。论文通过阅读相关文献资料,分析相关数据,以地震、滑坡和泥石流、土地荒漠化、地面沉降等地灾过程为分析对象,结合我国各地区地质发展史,研究我国地质灾害在时间和空间上的分布特征,试图找出其发育分布规律,对预测其未来发展趋势、预先建设相应防护措施、实施科学减灾、保护人们生命财产安全等有重要意义。
China has a vast territory and diverse topography, but it is also one of the countries with frequent geological disasters. Since the beginning of the 21 st century, with the changes of global climate, China’s geological disasters have occurred one after another, and the increasing of human economic activities in the process of social development has increased the frequency of geological disasters, resulting in the casualties and economic losses are on the rise.This paper analyzes related data by reading relevant literatures, and analyzes the distribution of geological disasters in China in terms of time series and space, taking earthquake, landslide and debris flow, land desertification and land subsidence as the analysis objects, and combining the geological development history of various regions in China, it studies the distribution characteristics of geological disasters in time and space, and tries to find out the distribution rules of geological disasters, which is of great significance for predicting its future development trend, pre-constructing corresponding protective measures,implementing scientific disaster reduction, and protecting people’s lives and property.
