| 摘 要： | 在地球演化历史上,第四纪是人类诞生、发展和壮大的时代,它所形成的地质产物中记录了丰富的生态环境信息。河北省境内第四纪岩石地层(泥河湾组、赤城组、马兰组、迁安组)的风化指数CIA,Fe2O3/FeO,Fe/Mn等地球化学参数可作为年均气温、年均降雨量等气候因子的近似代用指标;华北地区人类文化遗址所在地水系沉积物中Hg,Sn和Au等元素含量随人类文明的演进而阶段性增高。这一结果表明,人类为了适应不断变化的自然地理环境(寒冷、干旱),不得不进行技术创新,从而产生了农业耕作、工业革命及现代信息产业等文明进步成果,但与此同时,却也导致了地质环境的人为污染,甚至可能引发全球温室效应。

| Abstract: | In the evolutionary history of the Earth, Quaternary is the times of human birth, development and expansion and its formation geological products has recorded the rich environment information. Weathering index CIA,Fe2O3/FeO, Fe/Mn, etc., chemical parameters of Hebei Province Quaternary lithostratigraphics (Nihewan group, Chicheng group, Malan group, Qian’an group), may serve as the average annual temperature, annual rainfall and other climatic factors similar proxy. In the stream sediments of the location of the human cultural heritage sites in North China, mercury, tin, gold and other metal concentrations reach the higher stage with the evolution of human civilization. The results show that in order to adapt to changing natural geography environment (cold, drought) human being have to make technological innovation, resulting in the advances in the civilization as farming, industrial revolution and modern information industry. But at the same time, geological environment has also led to man made pollution, maybe even to global warming. |
