- 摘要:
- 选取河北太行山区典型坡面经济林板栗、苹果与立地条件相近的荒坡的枯落物蓄积量与持水能力进行研究。结果表明：枯落物总蓄积量范围为6.62~15.83 t/hm2，表现为板栗林总蓄积量最大，荒坡总蓄积量最小。枯落物最大持水量变化范围为13.41~53.9t/hm2。板栗林有效拦蓄量可达42.23 t/hm2，在各林分中最大；荒坡有效拦蓄量为19.55 t/hm2，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）。综合分析各林分枯落物层的持水能力，可知水土保持经济林持水能力远大于荒坡。
- Abstract:
- In order to provide a basis for the construction and planning of soil and water conservation forests of Taihang Mountain, the research for the water-holding capacity of litter was carried out in the four typical forests including Castanea mollissima Bl.forest, Malus pumia Mill.forest and controlled forestland. The litter water holding capacities in different kinds of forest stands were measured by indoor soaking method. The results showed that the litter total storage ranged from 6.62 t/hm2 to 15.83 t/hm2; the maximum water-holding volumes of different forests varied from 13.41 t/hm2 to 53.9 t/hm2,the order was Castanea mollissima Bl.forest > controlled forestland > Malus pumila Mill.forest; the effective retaining amount of litter was maximum in Castanea mollissima Bl. forest, while the minimum was found in the controlled forestland. The relationship between water-holding capacity of litter and immersion time could be described by logarithmic relationship (R>0.97), whereas the relationship between litter absorption rate and immersion time could be described by exponential relationship (R>0.98). Therefore,it was concluded from above that the water holding capacities of forestlands were much better than controlled forestland.
