红树林湿地环境污染地球化学的研究评述

Advances of studies on biogeochemistry of environmental pollution in mangrove wetlands

概要地回顾了近年来国内外红树林湿地环境污染方面的研究成果,介绍了红树林湿地沉积物中各种污染研究的主要内容、研究方法以及以后的研究方向。通过综合当前国内外本领域的研究进展资料,认为对红树林湿地环境污染地球化学的研究应加强复合污染的研究,并重视人类活动对红树林湿地污染历史中所扮演的角色。在污染物研究方面更应重视各种污染物尤其是重金属的生物有效性、迁移转化机理等的研究。在研究手段上,应注重运用同位素示踪和定年技术来研究污染物的来源和污染历史,应用高分辨率沉积物岩芯研究环境的变迁。研究还认为,应加强多学科的综合研究,以便为探讨红树林湿地的可持续发展以及污染红树林的生态修复提供依据。

In this article,the recent studies of biogeochemistry of the environmental pollution in the mangrove wetlands home and abroad were summarized. The main research contents, approaches and future trends were also presented. From the general analysis of literatures cited in this paper, it is concluded follows：First, it should strengthen to research the combined-pollution and much attention in the pollution history reconstructions of the mangrove wetlands. Secondly, for the pollutants, it should gained much more interests for their bioavailability and mechanisms of remobilizations, etc. Thirdly, for the research methods, the importance should be attached to the isotopes tracer and chronology,which can be employed to the research on the pollutants sources and history as well as the research on the environment changes using the high-resolution sediments cores in the mangrove wetlands. Finally, for future directions of environmental biogeochemistry in the mangrove forests, it should strengthen the multidiseiplinary comprehensive research to provide a basis for the sustainable development and restoration of the mangrove wetlands.
