摘　　要：生态地球化学在调查的基础上,以元素在不同生态系统中的循环为主线开展生态地球化学评价,通过输入输出通量调查和重访监测掌握元素循环的发展规律,从而对元素、化合物和其他地球化学参数的发展趋势进行预测预警,并提出开发或修复建议。近十年,该学科在实践应用的基础上进行理论框架和技术方法的不断拓展,不仅产生了大量技术标准、论文和专著等书面成果,还在污染控制、土地资源合理利用、特色农产品开发、土壤碳汇和抑制气候变化等方面产生了积极作用。在理论研究和应用实践需求的推动下在土壤碳库与全球变化、土壤重金属高背景产生机制、土地质量地球化学评价、土壤有益元素开发和土壤污染修复等方面不断产生分支研究方向。主要回顾和总结2011年以来,我国生态地球化学学科研究进展。Based on geochemical survey,eco-geochemistry assessment focuses on the circling of the elements in the ecosystems.And also,it investigates the input and output fluxes of soil elements,compounds,and other geochemical variables in order to predict the trend of their circling and make early-warning of risks.During the recent decade,the theoretical frame and the related techniques are under development with the emergence of a lot of technical standards,published articles and books.Furthermore,social and economic benefits have been produced in the aspects of pollution control,management of land resources,development of distinctive agricultural products,and even soil carbon sequestration and global warming prevention.Theoretical and practical requirements have pushed forward the development of eco-geochemistry and its branches have been developed in the areas of soil carbon sequestration,soil heavy metal from“high background”,geochemical assessment of land quality,development of soil beneficial element,and soil pollution control and remediation.This paper aims to summarize the progress of eco-geochemistry in China during the past decade.
