- 摘要:
- 为了更好地监测和评价森林持水能力,对华北山石区落桦混交林的枯落物层与土壤层持水能力进行研究。结果表明:落桦混交林中枯落物生物量、最大持水量、最大持水率、吸水速率和有效拦蓄量都是半分解层大于未分解层,其中半分解层的最大持水量是未分解层的1.36倍,半分解层的最大持水率为未分解层的1.1倍,半分解层的有效拦蓄量是未分解层的1.36倍。落桦混交林的土壤层持水能力为290.3 t·hm-2,其土壤的初渗速率为23.6 mm·min-1,稳渗速率为3.3 mm·min-1,土壤渗透性与入渗时间的拟合方程为f=26.666 t-1.036,相关系数为0.970。
- Abstract:
- In order to better monitor and evaluate the water holding capacity of forest,the water holding capacity of litter layer and soil layer of Betula platyphylla?and Larix principis-rupprechtii?mixed forest in North China mountainous area were studied.The results showed that the litter biomass,maximum water holding capacity,maximum water holding rate,water absorption rate and effective storage capacity of semi-decomposed layer were higher than those of the undivided layer in the mixed forest,and the maximum water holding capacity of the semi-decomposed layer was 1.36 times of that of undecomposed layer,the maximum water retention rate of the semi-decomposed layer was 1.1 times of that of the undivided layer,and the effective storage volume of the semi-decomposed layer was 1.36 times of the undivided layer.The soil water holding capacity of the mixed forest was 290.3 t·hm-2,the initial infiltration rate of the soil was 23.6 mm·min-1,the stable infiltration rate was 3.3 mm·min-1,the fitting equation of the soil permeability and infiltration time was f=26.666 t-1.036 and the correlation coefficient was 0.970.
