红树林重金属污染生态学研究进展

Research progress of heavy metal pollution in mangrove wetlands

红树林湿地,由于其固有的一些特性,能够大量接受来自潮汐、河水、地表径流所携带的重金属污染物。近30a来,红树林湿地重金属污染问题已引起了国内外学者们的极大关注,并对此进行了大量的研究。分别对重金属在红树林湿地中的分布与迁移、红树植物对重金属的生长响应及耐性机理等方面的研究进展和存在的问题进行了综述;此外,还对红树林湿地重金属净化效应的相关研究进行简要的概述。最后,对今后的研究趋势提出了一些看法。

Mangrove wetlands, due to their attributes, could receive a large amount of pollutants （ e. g. heavy metals） from local drainages, rivers and tides. Heavy metal pollution in mangrove wetlands has aroused great concern and a great number of relevant researches have been conducted in last three decades. The paper here reviews the research progress and some issues relating to distribution and transfer of heavy metals in mangrove wetlands, response and tolerant mechanisms to heavy metals by mangrove plants. In addition, it also summarizes metal purifying effects by mangrove system. Finally, the paper discusses the trends of future researches on mangrove wetlands.
