摘要
消落带区域是生态环境敏感脆弱地带,其严峻的生态环境安全问题成为国内外专家学者关注的焦点。如何减缓和阻止消落带自然植被的退化和萎缩,恢复和重建受损的消落带生态系统成为国内外研究热点。论文结合国内外消落带研究成果,概述了消落带的分类和功能,并从消落带存在的生态环境问题、植被生态修复与治理以及消落带的开发利用和管理等方面全面概述消落带国内外研究现状,在此基础上指出现有研究存在的不足,提出了今后消落带的重点研究方向。
The water-level-fluctuating zone is an ecological environment fragile zone, and its severe ecological environment safety problems become the research focus at home and abroad. How to slow down and stop the natural vegetation degeneration and atrophy in water-level-fluctuating zone, thus to restore and rebuild the damaged ecosystem has become a research focus. This paper reviewed recent foreign and domestic studies on the water-level-fluctuating zone. It first introduced the classification and functions of water-level-fluctuating zone, and then overviewed the research of the water-level-fluctuating zone from the following aspects： environmental problems brought about by human activities, ecological restoration and reconstruction, and exploitation and management of the water-level-fluctuating zone. On the basis of the review, it pointed out the existing problems and deficiencies in the research and put forward the outlooks in the future research.
