摘  要：
对雾灵山4个海拔梯度(820,995,1 080,1 270m)的油松(Pinus tabuliformis)人工林枯落物层及土壤层水文效应进行研究。结果表明:枯落物总蓄积量、最大持水量、有效拦蓄能力均随海拔升高先减小而后增大,最大持水率随海拔升高而减小,枯落物总储量在29.11~47.14t/hm2之间,最大持水量在61.13~128.31t/hm2之间,有效拦蓄能力在41.00~106.74t/hm2之间,最大持水率在192.50%~252.02%之间。枯落物持水量与浸泡时间呈明显对数关系,R>0.95,枯落物吸水速率与浸泡时间呈明显幂函数关系,R>0.99。土壤容重随海拔升高而增大,变化范围为0.66~0.95g/cm3,总孔隙度随海拔升高而减小,土壤层有效持水量随海拔升高而减小,土壤入渗速率与入渗时间呈明显幂函数关系,R>0.96。由此可知,低海拔油松人工林水源涵养能力普遍高于高海拔。

摘  要：
A preliminary study on hydrological effects of litters layer and soil layer in artificial Pinus tabuliformis forests was carried out in four different altitudes(820,995,1 080,1 270m)in Wuling mountain of Hebei. The result showed:With the increase of altitude,the litter total storage capacity,the maximum water holding capacity and the modified interception capacity decreased firstly,then increased,the maximum water holding rate decreased,the litter total storage capacity was about 29.11~47.14t/hm2,the maximum water holding capacity was about 61.13~128.31t/hm2,the modified interception capacity was about 41.00~ 106.74t/hm2,the maximum water holding rate was about 192.50%~252.02%.Water holding capacity and soaking time of without decomposition litter and semi-decomposition litter both had visible logarithmic relationship,R>0.95,absorption rate and immersion time was power function relationship,R>0.99.The soil bulk density increased with the increase of altitude,the average of soil bulk density ranged from 0.66 g/cm3 to 0.95g/cm3,with the altitudes increase,the total soil porosity and the soil water-holding capacity decreased,infiltration rate and infiltration fit time was power function,R >0.96.Generally,Pinus tabuliformis forest at low altitude had stronger water conservation function.
