摘要
植物生态系统中汞的环境过程是生物地球化学循环过程的重要组成部分,且与整个生态系统中各物种的生存和发展密切相关。本文介绍了植物中汞生物地球化学循环的进展,包括汞对植物的生物毒性、植物中汞的来源、分布与迁移转化、植物-大气间汞的交换过程及其研究方法,以及植被在生态系统间汞循环中的重要作用,最后简要介绍今后的研究重点和热点。
The environmental process of mercury in plants is a vital part in the bio-geochemical cycling process of mercury, with close relationship to the existence and development of species in the whole ecosystem. Some advances of researches on the bio-geochemical cycling process of mercury in plants have been reviewed in this paper. They include the bio-toxicity of plants caused by mercury in plants, the source, distribution, transportation and transformation of mercury in plants, mercury exchange processes between plants and atmosph,,re and their research methods, and the important function of vegetation on mercury cycling in the ecosystem. Finally, some key and hot research areas have been briefly addressed for further study.
