摘要:
在秦岭北坡水源林区选择不同针阔混交林和落叶混交林林分，对其土壤水文物理性质进行了研究。结果表明：土壤容重、非毛管孔隙度、最大持水量、毛管持水量和最小持水量均为针阔混交林大于落叶阔叶林，40 cm土层土壤水分平均(非毛管)滞留贮存量为针阔混交林大于落叶阔叶林。针阔混交林地土壤的渗透性能较好，其平均渗透系数达到了6.93 mm/min，是落叶阔叶林地的4.97倍，且同一林地内0-20 cm土层的渗透系数均大于20-40 cm土层。基于主成分分析，锐齿栎×油松(华山松)混交林地土壤的综合水文效应最优。
Abstract:
Different types of forest community in medium altitude of north Qinling Mountain were chosen to study the soil water physical characteristics. Result showed that in these forests, the soil bulk densities, non-capillary porosity, maximum water-holding capacity, capillary water-holding capacity and field water-holding capacity were ranked as mixed forests>deciduous broadleaved forest, while soil non-capillary porosity water-holding amount of 40cm layer was ranked as mixed forests>deciduous broadleaved forest. Permeability of mixed forest was 4.97 times higher than deciduous broadleaved forest and its mean permeability reaches 6.93 mm/min. Permeability of 0-20 cm layer was higher than that in 20-40 cm layer in different types of forest soil. Based on principal component analysis, the comprehensive hydrological effect of oak and pinus tabulaeformis(Pinus armandii) was the highest.
