| 中文摘要 | 以吉林省通榆县付老文泡和二百方子湿地为对象,对比研究了封闭性和开放性湿地土壤全磷含量的季节变化特征及其与土壤理化性状的关系。结果表明:付老文泡湿地0～100cm深度的土壤全磷含量范围为48.77～377.19mg/kg,二百方子为45.65～574.17mg/kg,随季节变化呈现先减后增的变化趋势,即12月-次年5月土壤全磷含量较高,5-7月逐渐下降,在7和8月出现最低值,9和10月含量较低且变化不大,10-12月含量又逐渐回升。土壤全磷主要分布在0～40cm土层,深层含量较低且差异不大;2类湿地土壤全磷含量均未达到生态毒性效应水平。植物地上部分全磷量与土壤全磷之间存在显著的正相关关系,付老文泡湿地植被生长受氮磷协同限制,而二百方子湿地植被主要受氮含量限制。2类湿地土壤全磷与土壤全氮、有机质及粘粒显著正相关,与土壤C/N无显著相关关系;但pH值仅与二百方子湿地土壤全磷显著负相关,与付老文泡湿地土壤全磷无显著相关关系。 |
| 英文摘要 | The Fulaowenpao and Erbaifangzi wetlands were chosen as typical sites in which to study characteristics of the seasona1 dynamics of total phosphorus (TP) in marsh soils from closed and open wetlands and to discuss the relationship between TP and other physical and chemical properties.TP content in the 0-100 cm depth of Fulaowenpao wetland soil ranged from 48.77 to 377.19 mg/kg,and in the Erbaifangzi wetland,from 45.65 to 574.17 mg/kg.On a seasonal basis,soil TP content in the two wetlands decreased first and then increased.From December 2008 to May 2009,soil TP content remained high,then decreased slowly from May to August.It remained very low during September and October,and finally gradually increased between October and December.Soil TP was mainly distributed in the 0-40 cm top soils in both wetlands,with a low content that was little different below.Soil TP content of the two wetlands did not reach a level that caused eco-toxic effects.There was an obvious positive correlation between plant TP and soil TP.However,the vegetation of Fulaowenpao wetland was restricted by nitrogen and phosphorus while there was limitation to Erbaifangzi vegetation only from nitrogen.There were remarkable positive correlations between soil TP and total nitrogen,organic matter and soil clay,and but no significant correlation between soil TP and soil C/N in the two wetlands.pH negatively correlated with soil TP in Erbaifangzi wetland,but not in Fulaowenpao wetland. |
