摘要

对冀北山地阳坡不同海拔蒙古栎天然林分枯落物层及土壤层进行了初步研究

结果表明:(1)样地二(海拔1 180 m)的枯落物总蓄积量最大为33.18 t/hm2

其次为样地三(海拔1 260 m)

最小为样地一(海拔1 100 m)

为14.20 t/hm2

即随海拔升高枯落物总蓄积量先增大后减小。最大持水率的变动范围为140.83%～229.81%

随海拔升高而降低。样地二的有效拦蓄力最强

为39.22 t/hm2

样地三拦蓄能力最弱

为20.58 t/hm2

即中海拔拦蓄能力最强

高海拔最弱。(2)枯落物吸水速度在开始1 h内较快

6 h后下降速度逐渐减慢。未分解层枯落物与半分解层枯落物持水量与浸泡时间呈明显对数关系(Q=aln(t)+b)

吸水速率与浸泡时间呈明显幂函数关系(V=ktn)。(3)土壤容重均值最大的为样地三(1.28 g/cm3)

最小的为样地二(1.08 g/cm3)

即随海拔升高先减小后达到最大。(4)样地三的土壤有效持水量最大

为98.75t/hm2

样地二的最小

为53.38 t/hm2

即高海拔土壤持水能力最强。利用幂函数对土壤入渗速率与入渗时间进行拟合

结果显示相关系数都在0.97...
