摘　　要：松嫩平原是中国内陆湿地集中分布区之一。该区湿地类型有沼泽、湖泊、盐沼和稻田,此外还有水库和少量泥炭地。概述了该区湿地的研究现状,并指出目前研究热点。重点探讨了未来本区湿地的研究趋势,主要体现在湿地生态系统结构、功能和过程研究,湿地的区域生态功能评价,湿地污染及其治理,退化湿地恢复和重建,湿地多样性与湿地保护,湿地资源综合利用,湿地对全球变化响应和全球变化对湿地影响,湿地-草地-盐碱地转换机制和过程和驱动力等方面。The Songnen Plain is the following area including the course of the second Songhuajiang River and Nenjiang River and their branches on the north of Song - Liao coteau, and on the west of mesa in the foot of eastern mountains in China. It is one of concentratively distributed area of inland wetlands. The wetlands in this region include marshes, lakes, salt sedges, paddyfields, reservoirs and little peatlands. They play important role in the sight, ecological construction and production of agriculture, pasture and fishery in the valley. So the wetlands in this area has been a prevalent research site. Much research work on all sort of wetlands have been developmenting in recent 10 years. Many academic and practical achievements have been finished. The research status of wetlands, such as function and benefit appraisal, substantial recycle and energy flow, resources utilization, protection and management, engineering and technology and formation and development of wetlands were summarized. The functions of wetlands in the Songnen Plain mainly embodies runoff adjust, flood deposit and reducing drought, pollution control, diversity keep and construction of landscape. The currency of expressing price is usually used for appraising the value and benefit of wetland ecosystem in this region. Phragmites australis is main plant in the wetland of the Songnen Plain, it is harvested for paper - making every year. Many precious and rare birds, such as Grus leucogeranus, Grus japonensis, Anthropoides virgo, Otis tarda dybowskii breed here. The types of wetlands are various. The landscape of wetlands are special. They are good spots for the tourists. The Xianghai, the Momoge, the Zhalong and the Chaganhu Nature Reserves have been famous travel sites now. Some wetlands face a austere degradation problem. The total area of wetlands gradually reduces, the function wears off. The water of wetland is polluted by waste water from industry, agriculture and life of local people to some extent. It is a complex system enginee
