| 摘 要： | 海河流域怀柔山地油松林生态系统N,P,S元素生物地球化学循环研究结果表明,生态系统氮素输入输出基本平衡。氮素、磷素在未来一段时间内将在植物凋落层中累积,硫则在凋落物层、土壤中累积。这种情况形成了城市郊区森林生态系统元素循环的独特特性。

| Abstract: | An investigation on the biogeochemical cycling of nitrogen, phospho-:rus and sulphur in a pinus tabulaeformis forest ecosystem in Haihe river basin revealed that the accumulation of N, P and S in the stand are 310.92, 31.31 and 30.34 kg/ha, respectively. The annual uptake of the three elements were found to be 37.43, 3.59 and 4.59 kg/ha and the return 12.60, 0.48 and 0.39, respectively. The amounts of N, P and S .accumulated in soil of 0-50 cm are 6399.3, 703.24 and 767.67 kg/ha, among which 741.89, 67.18 and 130.86 kg/ha are in available fraction. The annual input from precipitation and the output through leaching are 16.39 and 0.525 for N, 0.087 and 0.041 for P and 20.52 and 2.085 for S, all in kg/ha. The output due to runoff and soil erosion are 16.07, 0.97 and 7.01 kg/ha for three elements. The input-output is balanced for N, positive for S and negative for P. |
