协调人与地质环境的关系——Ⅰ人类活动对地质环境的影响

Coorndination between man and geologcal environment: influnce of human activities upon geological environment(Ⅰ)

从地质环境的基本属性和特征入手 ,重点探讨了人类活动对地质环境的影响。结论指出 :地质环境是生物圈、大气圈、水圈和岩石圈相互交汇而成的地质空间 ,具有空间性、稳定性、可变性和系统性等特征 ,是包括人类在内的所有生物的栖息地 ;由于人口的剧增和科学技术的发展 ,人类活动导致地质环境发生着深刻的变化 ,即改变着地球表面的形态、破坏了地表的植被、产生了新的地球化学过程、改变着水的循环途径和物质成分、改变着大气的成分和使物种减少。认为地质环境的变化直接影响着人类生活环境的质量 。

Geological environment (or the uperfacical earch system) which is composed of biosphere, atmosphere, hydrosphere and lithosphere, is the substantial foundation of all living beings including human.Geological environment has some regular properties (such as space,stability, deformation, system and so on). During geological history, changes of geological environment were caused by the interaction between internal geological agent and external one. At present, the human activities resulted in deformation of earth′s surface form, damage of vegetation, occurrence of neo geochemical process, change of circulation and constituent of water, variation of gas composition and decrease of species, which seriously influenced quality of environment of human existence.
