首发时间:2009-08-10
摘要:城市的发展标志着人类文明的发展,城市化是社会发展的必然趋势。进入2l世纪后,人类对城市发展赋予新的要求,力求在城市建设和发展中做到人与地质环境之间的和谐。城市地球化学所研究和关注的问题主要是城市化进程中的生态、环境、地质问题,运用地球化学的原理和方法,主要通过研究城市地下水、地表水、土壤、生物、大气及其降尘等环境体系中化学元素及同位素的分布、演化、环境作用及健康效应,查明污染源,对未来趋势作出预警并给出合理的治理途径。当今,城市地球化学在以下领域研究颇多并取得来了一定进展:新的理论模型的提出及应用;多途径示踪、解析城市环境污染源及其健康效应研究;地球化学工程学在治理环境污染中得以应用;建立典型地区城市地球化学风险性评价体系;加强了特定的地球化学条件下的模拟实验研究等。

Review on the Concerning Field of Urban Geochemistry
Abstract:The progress of cities indicates the human civilization, and the human society certainly needs more and more cities as human progress. After entering 21st century, we have new expectation for the cities and try our best to harmonizing the relationship between human and geology environment during the construction and development of the cities. As a subject, urban geochemistry mainly study and focus on the issue about ecology, environment and geology during the city’s progress, and it use the theories and methods of geochemistry to study the distributing, evolvement, action, and health effect of the element and isotopes in the environmental system such as groundwater, surface water, soil, biology, atmosphere, and air dust, so as to find out the reason of the pollution, give caution for the future, and give advice to control them rationally. Nowadays, urban geochemistry has gain certain production in these area: new theoretic models are put forward and applied; trail and explain the environmental contamination by many methods and study the health effect; geochemistry engineering is applied in dealing with the environmental contamination; build risk evaluation system for urban geochemistry in typical areas; do some simulate experiment research under given conditions.
Keywords: Urban Geochemistry Concern Field Review Theoretic Model
