摘要: 水岸带生态系统的保护、恢复和重建具有重要的科学意义和实践价值。笔者系统评述了水岸带生态系统功能研究进展,总结了国内外研究者对水岸带退化机制与生态修复的研究现状,分析了水岸带土壤重金属污染及其评价方法研究进展。就水岸带土壤生态环境及其修复研究而言,国外主要的关注焦点开始转向对退化水岸带生态系统的恢复以及水岸植被缓冲带的管理,而国内学者对水岸带生态系统恢复的理论及实践研究均较为薄弱。从水岸带土壤重金属污染研究来看,国内外水岸带都存在着不同程度的土壤重金属污染状况,并具有明显的生态风险,但主要的研究集中于土壤中重金属的赋存水平和污染现状分析,而没有能够将各环境因子、土壤生物对重金属的响应特征进行充分的考虑,导致了对区域内重金属可能存在的生态危害效应的评价不明。

Abstract: The protection, recovery and reconstruction of ecological system in riparian zone have important scientific value and practical meaning. The author reviewed the research progress of the function of ecosystem in riparian zone, summarized the degradation mechanism and ecological remediation both at home and abroad, analyzed the research progress of heavy metal pollution of riparian zone soil and its evaluation methodology. In terms of soil environment and its repair research, the foreign scholars focus on the research of the restoration of degraded riparian ecological system and riparian management of the vegetation buffer zone in recent years, while the research on the theory and practice of the restoration of riparian ecosystems are still weak in our country. In terms of the research of heavy metal pollution in riparian zone soil, riparian zone soil has heavy metal pollution in different degrees both at home and abroad, and it has obvious ecological risk. Current researches concentrate on the degree of heavy metal pollution in soil and the analysis of pollution status; domestic and foreign scholars have not taken environmental factors and the response characteristic of soil organism into account, this lead to an unclear evaluation of possible heavy metal ecological hazard.
