摘要
世界人口越来越向城市集中,城市化带来了城市地质环境变化,城市的地质环境研究已引起广泛的注意和重视。文章从地质环境、水文环境、大气环境和地球化学环境阐述了长沙市区的城市环境,提出进一步开展城市生态地球化学研究,对环境状态未来的变化进行预测,防止类似化学定时炸弹的地球化学灾害的发生,加强环境保护,使经济发展与自然环境和谐一致。
With the development of urbanization, more and more people swarm into cities, which finally brings about a series of changes in urban geological environment. Now much attention has been paid on the changes in urban geological environment. In this paper, the geological environment of Changsha City is described in detail, including its geological environment, atmospheric environment, hydrologic environment and geochemical environment, are respectively discussed. Based on the above, the authors think it is necessary to further develop urban ecological geochemistry, in order to forecast unborn environmental changes and prevent the occurrence of some geochemical catastrophic events such as chemical time bomb. The environmental protection is emphasized to reinforce the compatibility between economic development and natural environment.
