摘要

以冀北山地6种典型林分为对象，对其凋落物及表层土壤的水源涵养功能进行了初步研究。结果表明，各林分枯落物有效拦蓄量排序为:山杨林(3

t/hm

)>白桦林(

8.59 t/hm

)>蒙古栎林(

6t/hm

)>油松蒙古栎混交林(19.49 t/hm

)>华北落叶松林(13.53 t/hm

)>油松林(13.

3 t/hm

);各林分土壤最大持水量排序为:山杨林(1709 t/hm

)>油松蒙古栎混交林(1 551 t/hm

)>白桦林(1 549 t/hm

)>油松林(1547 t/hm

)>华北落叶松林(1357 t/hm

)>蒙古栎林(1 303 t/hm

);各林分土壤渗透性能排序为:油松蒙古栎混交林>山杨林>白桦林>油松林>蒙古栎林>华北落叶松林。采用层次分析法确定指标权重，对评价指标值进行计算分析，比较不同林分综合水源涵养功能，结果认为，油松蒙古栎混交林的综合水源涵养功能最好，其次为山杨林、白桦林、蒙古栎林、油松林，华北落叶松林最差。

Abstract

Experiments were conducted to study the water conservation functions of litter and surface soil under six forest types in mountainous area of Northern Hebei Province.The results show that in terms of effective interception capacity

the rank of litter layers was poplar forest( 32.32 t/hm2)>birch forest(28.59t/hm2)>Mongolian oak forest(20.26t/hm2)>chinese pine-Mongolian oak mixed forest(19.49t/hm2)>Larix principis-rup prechtii forest( 13.53 t/ hm2)>chinese pine forest(13.23t/hm2);in terms of soil maximum water-holding capacity

the order was poplar forest> chinese pine-Mongolian oak mixed forest>birch forest>chinese pine forest>Larix princip is:rupprechtii forest> Mongolian oak forest; regarding soil infiltration characteristics

the rank was chinese pine-Mongolian oak mixed forest> poplar forest> birch forest> chinese pine forest> Mongolian oak forest> Larix principis - rupp rechtii forest.The values of evaluation indices were calculated based on weights that were determined using the method of hierarchy analysis.The evaluation results show that chinese pine-Mongolianoak mixed forest had the best water conservation function

followed in order by poplar forest

birch forest

Mongolian oak forest

chinese pine forest

and Larix principis-rup prechtii forest had the worst.
