2000年前后区域环境地球化学研究的前景与设想——关于“九五”规划及21世纪环境地学发展项目的建议

本文提出一种研究区域环境地球化学解决宏观环境问题的新思路,按照环境—地球化学—地质构造三对应的原则提出“八五”后期、“九五”和2000年后区域环境地球化学分阶段发展的设想。除了为国家提供保护治理环境的决策依据外,区域环境地球化学在理论上需要建立起地质地球化学—生态系统物质大循环模型,进行典型环境元素全球对比研究。

PROSPECT AND TENTATIVE PLAN OF REGIONAL ENVIRONMENT GEOCHEMISTRY RESEARCH AROUND THE YEAR 2000

This paper puts forword a new idea of studying regional environment geochemistry, an analysis of tectonic geochemistry. On the three reciprocal bases of environment, geochemistry and tecton, we classify China into two regions; one is the eastern secondary geochemistry pollution region caused mainly by human beings; the other is the western primary geochemistry region controlled by tectonic role. Each region is respectively divided into pollution sub-areas and tectonic geo chemical abnormal environment zones. On the basis of this classification, the paper suggests a stage-developing plan for regional environment geochemistry from now to the early twenty-first century. The basis for policy-making of environmental protection and administration of our country is provided and a big material cycling pat tern in geochemical-ecological system is set up. A global correlation plan of typical environment elements such as Selenium, Molybdenum, Arsenic and Fluor will go on from the study of the regional environment geochemistry.
