摘要

[目的

]

探讨计划烧除对枯落物蓄积特征及持水性的影响，为科学实施森林计划烧除措施和评价计划烧除的生态环境效应提供理论支撑。[方法

]

枯落物蓄积量采用样方调查法计算，枯落物持水量采用室内浸泡法测定，枯落物年输入动态调查采用野外定位收集器法。[结果

]

①计划烧除样地燃烧剩余物蓄积量为3.84 t/hm

，仅为未烧除样地枯落物蓄积量的21%；未烧除样地枯落物蓄积量为18.64 t/hm

。②计划烧除样地燃烧剩余物最大持水量14 t/hm

，未烧样地分枯落物最大持水量60.62 t/hm

，计划烧除和未烧除样地枯落物层持水量与浸泡时间符合对数函数关系，枯落物层吸水速率与浸泡时间呈幂函数关系。③计划烧除和未烧除样地枯落物年输入总量相似，最大输入量在4月，占全年增加量的20%～24%，1 a后计划烧除样地的有效持水量恢复到未烧除样地的73%。[结论

]

云南松林计划烧除后，短期内枯落物蓄积量减少，枯落物持水能力降低，枯落物输入量无显著差别。

Abstract

[Objective] The influence of prescribed burning on accumulation and water holding capacity of litters in Pinus yunnanensis forest was investigated

in order to provide a scientific basis for predicting the environmental effects of prescribed fire.[Methodes] The litter accumulation amounts and hydrological characters were tested and compared between the unburned and burned forests by prescribed fire. Litter accumulation amounts were obtained by field positioning collector methods and the hydrological character was investigate indoor immersion method.[Results] ① The volume of combustion residue after prescribed fire sample plot was 3.84 t/hm2

which was only 21% of the volume of litter in the unburned sample plot

and the volume of litter in the unburned sample plot was 18.64 t/hm2. ② The maximum water-holding capacity of forest litters after prescribed fire was 14 t/hm2

which was significantly lower than that in unburned forest with the total maximum water-holding capacity of 60.62 t/hm2. The water-holding capacity of the litter layer and soaking time in both unburned and prescribed burned sample land showed a significantly logarithmic relationship

and the immersion time and the absorption rate of forest litters showed a significantly power function relationship with the immersion time. ③ The maximum amount of litter input was in April

accounting for 20%-24% of the annual increase. After 1 year

the effective water-holding capacity in the prescribed burnt land was restored to 73%.[Conclusion] After the prescribed fire

the litter storage and the waster holding capacity can decrease in short term. However

with the natural recovery

the water conservation of the litter of Pinus yunnanensis forest can gradually recover.
