摘　　要：从森林林冠层、林下枯落物层、土壤层3个生态作用层对冀北山地森林生态系统水文生态效应进行研究,运用层次分析与数学软件MATLAB相结合的方法,综合评价冀北山地落叶松桦木针阔混交林、山杨桦木阔叶混交林、油松蒙古栎针阔混交林3种主要森林植被类型的涵养水源功能的强弱,并进行了排序。结果为:落叶松桦木针阔混交林(0.348 4)>油松蒙古栎针阔混交林(0.334 1)>山杨桦木阔叶混交林(0.317 5)。事实证明,层次分析法是评价森林涵养水源功能的一种非常有效的数量化方法。This article studied the hydrological,ecological effects of of the forest ecosystem through three layers of forest canopy,litter and soil.The water conservation function of 3 main types of mixed forest of Larix and Betula,Populus and Betula,Pinus and Mongolica in Mountainous area of north Hebei Province was evaluated by the method of Analytical Hierarchy Process（AHP）combined with the software MATLAB.The forest types were listed as follows：the mixed forest of Larix and Betula（0.348 4）the mixed forest of Pinus and Mongolica（0.334 1）the mixed forest of Populus and Betula（0.317 5）.It is proved that AHP is an effective quantitative analysis method for evaluating forest function in water conservation.
