摘要: 中国是世界上地质灾害最严重的国家之一。地质灾害种类多、分布广、活动频繁,直接危害人类生命财产安全,破坏资源环境,对社会生活和经济建设造成广泛而又深远的影响。在气候、地形、地质构造和社会条件等多种因素影响下,不同地区地质灾害的种类、强度和破坏程度差异甚大。该文将全国分为东部和西部两大灾害区,每个灾害区又划分若干亚区。地质灾害活动具有不规则的周期性和累进性特点。多数地质灾害在强弱变化中显示不断增强的趋势。未来从可持续发展的高度,防治地质灾害乃是一项长期而又艰巨的任务。Abstract: China is among the countries that have most serious geological disasters.The geological disasters wide-spread in China are of varied types and frequent occurrence, not only harming lives and properties of the people, but also deteriorating the natural resources and environment.The resulting losses have a wide profound influence on the social economy. Due to widely varied conditions of climate, landform, geological structure and social condition, there is considerable difference in their types, strength and destructiveness in different areas.Broadly we have two large hazard-striking regions, the east region and west region, which are divided into a number of subregions.Their occurrences are mostly found to be irregular cyclic and accumulative.In the future, the prevention and control of geological disasters will be a very arduous task over certain period of time.
