以太子河源头水源涵养林为研究对象,分析不同植被类型地表径流和壤中流的氮流失特征,运用冗余分析和偏冗余分析对氮流失特征与环境因子之间的关系进行分析,并对其主要影响因子进行定量分解,探寻太子河源头水源涵养林氮流失特征的关键影响因子。结果表明:不同植被类型地表径流和壤中流硝态氮是氮流失的主要形态,地表径流硝态氮的浓度是铵态氮浓度的1.5倍,壤中流硝态氮的浓度是铵态氮浓度的20.5倍。无论是地表径流还是壤中流铵态氮和硝态氮流失浓度的大小顺序均为人工林>杂木林 >次生林。受径流量和壤中流量的影响,铵态氮流失量表现为次生林最大,硝态氮流失量表现为人工林最大。土壤物理性质和土壤...

The characteristics of mineral nitrogen loss through surface flow and interflow in different types of vegetation in a water conservation forest were analyzed in the headstream of Taizi river.To explore the limiting factors which affect nitrogen loss,redundancy analysis and partial redundancy analysis were applied to study the relationship between nitrogen loss and environmental factors,and quantitative analysis was applied among the main influential factors.The results showed that nitrate nitrogen was the main form of nitrogen loss in both the ...
