Abstract
本文以二百方子湿地和付老文泡湿地为研究对象,对比分析了两典型区湿地土壤不同形态氮素和全氮含量在生长期和成熟期的剖面分布特征及其差异,结果表明封闭性湿地和开放性湿地土壤剖面的物理性状存在地域差异;封闭性湿地在两物候期内土壤氮素含量的剖面分布特征相似,均表现为由表层向下减少的总体分布趋势;开放性湿地土壤中碱解氮、有机氮和全氮含量剖面分布特征与封闭性湿地一致;但铵态氮含量的剖面变化则表现为先增后减的变化趋势,且硝态氮在成熟期内出现累积峰.;Erbaifangzi (EBFZ) wetland and Fulaowenpao(FLWP) wetland were chosen for study sites, and the diofribution characteristics of total nitrogen and different forms of nitrogen contents in soil profiles were studied in the two sites.The results showed that there existed regional difference for physical properties of soil profiles in the two sites;It was similar for the distribution characteristics of nitrogen contents in two climate periods in close wetland, decreasing gradually from top down;the distribution characteristics of available nitrogen, organic nitrogen and total nitrogen in open wetland were consistent with those in uclose? wetland;However, content of ammonium nitrogen content in soil profiles appeared the changing tendency of' decreasing after increasing, and there was an accumulative peak in soil profile during maturity period in open wetland.
