摘要
火烧对湿地生态系统的影响是国内外火生态学和湿地生态系统研究中的一个热点。综述了国内外关于火烧对湿地生态系统各组成部分影响的研究进展,总结了湿地火烧的特点,火烧对湿地植物生长发育、群落特征的影响,火烧对土壤理化性质、对土壤中碳氮等元素形态及分布特征的影响。并针对目前湿地火烧在研究内容和方法上存在的问题,结合国外研究特点,提出了今后国内湿地火烧的研究展望。
Effects of fire on wetland ecosystem is a hot research issue for fire ecology and wetland ecology globally.Fire plays an important role in wetland ecosystem,and thus recent studies about effects of fire on wetland ecosystem are reviewed in this paper.The variations of plant growth,soil physicochemical properties and nutrient cycle （e.g.C,N） after fire in wetland ecosystem are summarized.Problems about study emphasis and methods of fire in wetland ecosystem at present are pointed out.We found out that the changes of functions and processes of wetland after fire were fairly important and needed to be discussed in more detail.Finally,this paper puts forward the prospect of domestic studies of fire in wetland ecosystem in combination with the characteristics of relative researches in other countries.
