摘要：阐述了用灰色关联度法评价森林涵养水源生态效益的理由和步骤,以辽东山区主要森林类型的评价为例,选取的指标包括:平均树冠截留量、枯落物含水量、土壤非毛管孔隙最大含水量、蒸发散量、渗透速率,根据关联度大小,对各森林类型的涵养水源生态效益和各个指标重要程度进行对比,在辽东山区的森林中,落叶松中龄林的涵养水源生态效益最佳,其次为杂木林、红松中龄林、红松幼龄林、落叶松幼龄林和柞树林;各项指标的重要程度由大至小依次为土壤非毛管孔隙最大含水量、蒸发散量、平均树冠截留量、枯落物含水量和土壤渗透速率。
The reason and process of estimating water-feeding benefits of forest ecosystem were expatiated with the gray correlation method.The case is mostly important forest style in Liaoning province eastern mountainous area.The indexes include canopy interception,water absorption capacity of the litter,water absorption capacity of soil,forest evaporation and transpiration,infiltration velocity.The results indicated that half mature larch have best water feeding benefit among some forest style,and later is weed tree,half-mature Korean pine,young growth Korean pines,young growth larch and the last is oak.The turn of factors from high importance to low is water absorption capacity of soil,evaporation and transpiration,canopy interception,litter's water absorption,infiltration velocity.
