摘要
在青藏高原东北边缘地带,考古挖掘出的青海喇家遗址史前场景和10 a前我们所目睹过的舟曲特大泥石流,均属于突发性、毁灭性自然灾难事件。从"将今论古"的视角出发,对发生在青藏高原东北边缘古今两次灾害事件的成因机制进行了对比分析。结果认为,相隔近4000 a的这两次毁灭性灾害事件,均是发生在青藏高原东北边缘构造活动带特定地理环境下由量变到质变的结果,在不同空间上相似的悲剧性灾难事件不断地重演,人类在吸取教训上做得不够,对安全隐患的感知是不能遗传的,相比较人的平均寿命来说,当灾害事件所发生的频率较低时,会误以为自然环境是安全的。由此,在城镇居所选址上缺乏科学的规划,对居所存在的灾害隐患没有得到应有的警惕。本文建议人类应提高防范意识,居安思危,慎重选择居住地,挖掘历史灾害事件,以史为鉴,科学合理地安置居所,尽量避开灾害易发地段,保护自然生态环境,避免过度开发破坏,树立"青山绿水,就是金山银山"的科学理念。
On the northeastern edge of the Qinghai-Tibet Plateau,the prehistoric scenes of the Lajia site in Qinghai unearthed by archeology and the extremely large mudslides in Zhouqu that we have witnessed ten years ago are all sudden and devastating natural disasters.From the perspective of"combining the present and discussing the past",a comparative analysis of the cause mechanism of the ancient and modern disasters that occurred on the northeastern edge of the Qinghai-Tibet Plateau was conducted.It is concluded that the two devastating disaster events separated by nearly 4000 years are the result of quantitative changes to qualitative changes in the specific geographical environment of the tectonic activity zone on the northeastern edge of the Qinghai-Tibet Plateau.Similar tragic disasters in different spaces continue to repeat themselves.Human beings have not done enough to learn lessons,and their perception of safety hazards cannot be inherited.Compared with the average life span of people,when the frequency of disaster events is low,they will mistake the natural environment for safety.As a result,there is a lack of scientific planning on the site selected for urban residences,and no due vigilance is given to the hidden dangers of disasters in the residences.This article suggests that human beings should improve their awareness of prevention,be prepared for danger in times of peace,carefully choose residences,dig out historical disaster events,learn from history,arrange residences scientifically and reasonably,avoid disaster-prone areas as much as possible,protect the natural ecological environment,avoid excessive development and damage,and establish the scientific concept of"green mountains and green waters are golden mountains and silver mountains".
