为了研究三峡库区不同林分类型马尾松林的枯落物持水性能,采用野外调查和室内浸泡法,对马尾松纯林(Ⅰ)、马尾松+香椿混交林(Ⅱ)、马尾松+檫木混交林(Ⅲ)、马尾松+盐肤木混交林(Ⅳ)、马尾松+槲栎+檫木混交林(Ⅴ)、马尾松+光皮桦混交林(Ⅵ)、马尾松+木姜子混交林(Ⅶ)7种马尾松林分类型枯落物持水特性进行了研究。结果表明:三峡库区不同林分类型马尾松林枯落物储蓄量为5.39~11.77 t/hm2,枯落物总厚度变化范围为2.14~3.73 cm,枯落物总蓄积量排列顺序为Ⅲ > Ⅳ > Ⅵ > Ⅱ > Ⅴ > Ⅰ > Ⅶ,最大持水量变化范围为11.94~23.42 t/hm2,最大持水率变化范围为198.53%~266.17%,7种类型马尾松林枯落物有效拦蓄量范围为8.34~15.90 t/hm2,有效拦蓄率范围为135.79%~195.81%,不同类型马尾松林枯落物有效拦蓄量排序与最大持水量排序相一致,均表现为Ⅲ > Ⅴ > Ⅳ > Ⅰ > Ⅱ > Ⅵ > Ⅶ。而枯落物有效拦蓄率排序除了类型Ⅶ和类型Ⅱ,其他类型大小顺序与最大持水率保持一致。7种类型马尾松林枯落物持水量随着浸泡时间延长呈对数形式增加,浸泡5 min时,不同林分类型枯落物吸水速率最大,浸泡1 h后,不同层次枯落物吸水速率均呈现缓慢下降。吸水速率V与浸泡时间t以幂函数拟合效果较好,吸水速率随着浸泡时间延长以幂函数形式降低。
In order to study the water holding capacity of the litter of Pinus massoniana plantation in different forest types in the Three Gorges Reservoir Area
the methods of field survey and soaking extraction was applied to study the water holding capacity of P. massoniana plantation (Ⅰ)
P. massoniana + Toona sinensis mixed forest (Ⅱ)
P. massoniana + Sassafras tzumu mixed forest (Ⅲ)
P. massoniana + Rhus chinensis mixed forest (Ⅳ)
P. massoniana + Quercus aliena + Sassafras tzumu mixed forest (Ⅴ)
P. massoniana + Betula luminifera mixed forest (Ⅵ)
P. massoniana + Litsea pungens mixed forest (Ⅶ). The result showed the litter amount in different types of P. massoniana forest in the Three Gorges Reservoir Area ranged from 5.39 t/hm2 to 11.77 t/hm2
the litter thickness ranged from 2.14 cm to 3.73 cm
and the order of total litter amount was Ⅲ > Ⅳ > Ⅵ > Ⅱ > Ⅴ > Ⅰ > Ⅶ
the maximum water holding quantity ranged from 11.94 t/hm2 to 23.42 t/hm2
the maximum water holding rate ranged from 198.53% to 266.17%. The effective interception of the seven types of P. massoniana forest litter ranged from 8.34 to 15.90 t/hm2
and the effective interception rate ranged from 135.79% to 195.81%
the effective interception of litter and the maximum water holding quantity
all showed Ⅲ > Ⅴ > Ⅳ > Ⅰ > Ⅱ > Ⅵ > Ⅶ. However
except for Type Ⅶ and Type Ⅱ
the effective interception rate was consistent with the maximum water holding rate of other types. The water holding capacity of seven types of P. massoniana plantation increased logarithmically with the soaking time. After soaking for 5 minutes
the water absorption rate of litter in different forest types was the highest
and it showed slow decline after soaking for 1 hour. The water absorption rate V and socking time t fit better with power function
and the water absorption rate decreased with the prolongation of the soaking time in power function form.
