摘    要:湿地生态系统在全球碳循环中有着举足轻重的作用。由于湿地垦殖、农业化施用等人类活动和全球变暖、大气氮沉降的增多等自然因素的综合作用,大量氮磷营养物质进入湿地,这必将对湿地生态系统碳蓄积产生影响。本文综述了外源氮磷输入对湿地土壤碳库、植被碳库和枯落物分解的影响以及湿地生态系统碳循环的模型研究,并对以后发展趋势进行了预测。

关 键 词:氮输入  磷输入  碳蓄积  湿地生态系统

Abstract:Wetland system plays an important role in global carbon cycle.Human activities,such as wetland cultivation,agricultural fertilizer using and natural factors,such as global warming,atmosphere nitrogen deposition result in amounts of nitrogen and phosphorus nutrition entering into wetland,which must effect the carbon accumulation in wetland system.This paper summarized the effects of exogenous nitrogen and phosphorus inputs on soil carbon pool,plant carbon pool,litter decomposition in wetland,and the model simulation of carbon cycle.And a research prospect in this field has been pointed out.
Keywords:Nitrogen input  Phosphorus input  Carbon accumulation  Wetland system
