摘　　要：基质是湿地生态系统发育和存在的载体,稳定的基质是保证湿地生态系统正常演替与发展的基础,湿地基质恢复研究是当今世界湿地科学关注的重要问题之一。基质恢复理论较为复杂,仍存在着一些迫切需要解决的问题。文中从基质的类型和作用出发,阐述了湿地基质的退化表征,提出了湿地基质恢复技术,包括湿地基质改良、湿地基质清除、湿地基质再造等方法,其中基质改良又有物理改良、化学改良和生物改良3种方式。Substrate is the carrier of wetland ecosystems presence and development,and stable substrate is the basis to ensure the normal succession and development of wetland ecosystem.Restoration of wetland substrate is therefore one of the important issues for the world＇s wetlands science.Wetland substrate restoration is therotically complicated,and there are still some pressing problems needed to tackle.By defining types and functions of wetland substrate,the paper described the characterization of degradated wetland substrate,and then proposed techniques for wetland substrate restoration including wetlands substrate improvement,wetland substrate removal,wetland substrate reforgement and other methods,in which wetland substrate improvement contain 3 methods,i.e.physical improvement,chemical improvement and biological improvement.
