对中国北方山区6种典型森林的森林凋落物和土壤水文效应进行了比较研究。结果表明：6种典型林分凋落物总储存量为6.35~23.32 t/hm2，具体顺序为云杉林—落叶松林—松林—白杨林；6种林分的最大持水率范围为250.46%~56.47%，有效持水能力范围为14.67~50.85 t/hm2，其中以松林凋落物水文效应最差；6种典型森林土壤的平均容重和总孔隙度无显著差异；变化幅度为1.006~1.128 g/cm3, 57.434%~64.001%；6种典型森林土壤的总持水量范围为1 618.264~2 685.788 t/hm2, 6种典型森林土壤的相对持水量顺序为落叶松-云杉林-落叶松-云杉林-白杨林-松林，但稳定入渗时间几乎没有差异，20 min后，所有类型的入渗速率为0.24~0.30 mm/min。
A comparative study on hydrological effects of forest litters and soil about 6 typical forests was carried out in north China mountainous region.The results showed that the total storage capacity of 6 typical forests litter was 6.35~23.32 t/hm2,the specific sequence was spruce forest larch-Spruce forest Larch forest Chinese-pine forest Broadleaf-Chinese-pine forest birch-poplar forest;the scope of the maximum water-holding rate for six types forests was 250.46%~56.47%,and the effective water-holding capacity was14.67~50.85 t/hm2,the hydrological effects of Chinese-pine forest litter was the worst among the six types;the average soil bulk density and total porosity of 6 typical forests were not different;the changes were 1.006~1.128 g/cm3 and 57.434%~64.001%;the scope of the total water-holding capacity of 6 typical forest soil was 1 618.264~2 685.788 t/hm2,and the relative water-holding capacity sequence of the 6 typical forest's soil was larch-Spruce forest Larch forest spruce forest Broadleaf-Chinese-pine forest birch-poplar forest Chinese-pine forest,but the stable infiltration time almost had no difference,after 20 min,the infiltration rate of all types was 0.24~0.30 mm/min.
