[目的
]
揭示人工水土保持林林下枯落物以及土壤持水特征,为太行山区水土保持林的建造和规划提供理论依据。[方法
]
运用烘干法,室内浸泡法,环刀法等得出不同林分林下枯落物蓄积量、持水量、吸水速率、最大持水能力和拦蓄量,比较了不同林分枯落物和土壤的持水能力。[结果
]
枯落物总储量范围为9.96~19.19 t/hm
2
,表现为栓皮栎林总储量最大,荒坡总储量最小。枯落物最大持水量变化范围为23.76~66.72 t/hm
2
,栓皮栎—侧柏混交林最大,荒坡最小。栓皮栎—侧柏混交林有效拦蓄量可达51.50 t/hm
2
,在各林分中最大;荒坡有效拦蓄量为19.55 t/hm
2
,在各林分中最小。枯落物持水量、吸水速率均与浸泡时间呈相关关系,前者为对数关系(
R
> 0.97),后者为幂函数关系(
R
> 0.98)。各林分土壤容重均值介于1.14~1.55 g/cm
3
,总孔隙度介于38.62%~43.76%。各林分土壤有效持水量表现为:刺槐林> 栓皮栎—侧柏混交林> 栓皮栎林> 荒坡,其中刺槐林最大(为106.85 t/hm
2
),荒坡最小(为89.37 t/hm
2
)。[结论

水土保持林持水能力远大于荒坡。
[Objective] The objective of this study is to investigate the water-holding capacity of litter and soil and to provide support for planning and planting soil and water conservation forests in Taihang Mountains. [Methods] Drying method
indoor soaking and cutting ring method were used to determine the water holding capacity by litter and soil in different kinds of forest stands. [Results] The total storage by litter ranged from 9.96 t/hm2 to 19.19 t/hm2. The maximum water-holding volume of different forests was about 23.76 t/hm2 to 66.72 t/hm2
the order was Quercus variabilis and Platycladus orientalis mixed forest >Q. variabilis forest >Robinia pseudoacacia forest> controlled forestland. The maximum effective retaining water of litter occured in Q. variabilis and P. orientalis mixed forest while the minimum in controlled forestland. The water-holding capacity of litters and immersion time had visible logarithmic relationship(R>0.97)
whereas the litter absorption rate and immersion time followed an exponential relationship(R>0.98). Soil bulk desity was about 1.14 g/cm3 to 1.55 g/cm3
the total porosity ranged from 38.62% to 43.76%. The order of effective water-holding capacity of soil in these forests was R. pseudoacacia forest>Q. variabilis and P. orientalis mixed forest>Q. variabilis forest>controlled forestland( maximum in R. pseudoacacia 106.85 t/hm2
while minimum in controlled forest land 89.37 t/hm2). [Conclusion] The water holding capacity of forest lands was much better than controlled forestland.
