| 摘 要： | 试验在中国科学院海北高寒草甸生态系统定位站进行了实验样地设置在冬春草场上，应用分室模型，将高寒草甸生态系统分为大气，土壤，植物，食草动物４个分室，主要讨论了磷素在各分室内的贮量，流动方向，流通数量及其系统磷素的供需状况，高寒草旬生态系统磷素的循环过程中，大气分室通过降水输入土壤磷量为０．３６ｋｇ／ｈｍ＾２．ａ植物从土壤库摄取速效磷７．０６ｋｇ／ｈｍ＾２．ａ这些磷素一部分（０．５７ｋｇ／ｈｍ＾２．ａ

| Abstract: | This study was carried out at Haibei Research Station of Alpine Meadow Ecoystem and the experiment plot was set on winter spring pasture.Using a compartment model.we divided the ecosystem into four compartments,they are atmosphere,soil,vegetation and grazing animal compartments.We measured the P storage in each of the compartments,and studied the direction and the amounts of P flowing among these compartments,and its' supply requirement state in the ecosystem.the P cycling process in the Alpine Meadow Eco... |
