本文研究了辽宁东部山区森林土壤的渗透性能和蓄水能力。结果表明 ,辽东林区土壤的有效蓄水量 90 0～ 1 6 0 0t/hm2 ,土壤表层的初渗速度 2 7 9～ 6 1 6mm/min ,稳渗速度 2 6～ 4 2mm/min。天然次生林土壤的渗透性能及蓄水能力优于人工针叶林。
This paper studied the forest soil permeability and water storage capacity in eastern Liaoning. The results showed that the effective storage of soil in Liaodong forest area was 90 0 ~ 16 000 t / hm2, the initial infiltration rate of soil surface was 279 ~ 61 6 mm / min and the steady infiltration rate was 26 ~ 42 mm / min. Natural secondary forest soil permeability and water storage capacity better than artificial coniferous forest.
