世界上70%的滑坡与人类工程—经济建设活动有关。20世纪以来,人为因素形成的地质作用,每14—15年即翻一番,可见其速率之快。在我国,据最新资料统计,滑坡、泥石流,崩塌、地面沉降、土地沙化等地质灾害,有一半以上是人为因素诱发。人为的地质作用速率快、影响广、灾害多。专门研究人类有史以来的生产活动引起的地质地貌现象及其影响,已有专门的学科一环境地质学应运而生。这门学科研究的地质历史虽属第四纪,却有其独特的专
About 70% of the world’s landslide is related to human engineering-economic construction activities. Since the 20th century, the geological effect of human factors has doubled every 14-15 years and shows its rapid rate. In our country, more than half of the geological disasters, such as landslides, debris flows, landslides, land subsidence and land desertification, are caused by human factors according to the latest statistics. Artificial geological effects of rapid rate, wide impact, disaster and more. Specializing in the history of mankind’s production activities caused by geological phenomena and their impact, there has been a special discipline of environmental geology came into being. Although the geological history of this discipline is Quaternary, it has its own unique specialty
