采用烘干法、环刀法、渗透筒法和机械筛分法对泰山 4种坡面经济林的土壤水分物理性质及持水、透水能力进行了研究。结果表明 ,4种经济林的土壤孔隙度为 4 3.3%～56 .6 %之间 ;饱和持水量为 86 .6 0～112 .4 0mm之间 ;毛管最大持水量为 6 6 .6 0～ 90 .2 0mm之间 ;有效涵蓄水量为 36 .2 8～ 58.12mm之间 ;渗透系数为 3.99～ 8.84。均明显高于对照 (草坡 ) ,其中以板栗林和苹果园土壤持蓄水和渗透能力最强 ,可作为石质山地发展坡面水土保持经济林的首要树种。
The physical properties of soil moisture and water holding capacity and water permeability of four types of slope economic forest in Mount Tai were studied by drying method, ring cutter method, permeation tube method and mechanical screening method. The results showed that the soil porosity of four kinds of economic forest was between 4.3% and 56.6%, the saturated water content was between 86.600 and 112.400mm, the maximum water content of capillary tube was between 6.66 and 90.0% .2 0mm between; the effective storage of water between 36.28 ~ 58.12mm; permeability coefficient of 3.99 ~ 8.84. Were significantly higher than the control (grass slope), of which the chestnut forest and apple orchard soil holding water and the strongest penetration, can be used as stony mountain slope soil and water conservation economic forest primary tree species.
