| 摘 要： | 按照湿地的水文周期和水流状态,将松嫩平原芦苇湿地分为两种水文类型,即闭流型和外流型.1998年强降水和洪水季节,通过野外径流场观测、水量平衡分析和样品室内测试,分析了两种水文类型的芦苇湿地中磷素的水文迁移过程和养分收支平衡.结果表明,闭流型芦苇湿地一直是磷汇;而外流型芦苇湿地,随季节变化而发生磷源和磷汇的交替.

| Abstract: | According to hydrological cycle and water regime, wetlands on Songnen Plains are divided into to two kinds of hydrological types: outflow wetlands and closed wetlands. By the field runoff observation and determination of some water samples, the hydrogeochemical migration process and budget of phosphorus in the two reed wetlands during heavy precipitation and flooding period are analyzed. The results show that the closed wetland is always the sink of phosphorus, but the outflow wetland change with the season between the source and sink of phosphorus. |
