摘  要：
本试验运用固定标准地观测的方法测定辽东山区几种主要林分类型的蒸发散量,根据布兰尼—尼里德尔模型推算的后楼水库集水区邻域范围内的年土壤和枯落物水分蒸发量分别为落叶松幼龄林720 mm/a、落叶松中龄林751 mm/a,红松幼龄林762 mm/a、红松中龄林826 mm/a、柞树林677 mm/a、杂木林741 mm/a。影响单位面积蒸发量的主要因子为地表枯落物量,同时蒸发量又与郁闭度呈弱的负相关关系,地表至20 cm的表层土壤的水分蒸发量约占总蒸发量的绝大部分;各个林分类型间的蒸腾量差异显著。

摘  要：
This paper comparatively studies evapo-transporation of 6 representative forest types,such as young growth larch,half-mature larch ,young growth Korean pine,half-mature Korean pine,oak,weed tree,in mountain- ous area of eastern Liaoning by observing fixed plots.With the model of BLANEY-CRIDDLE,the amount of evapo- transporation in each vegetation type in mountainous areas of eastern Liaoning was estimated.The results were as follows:young growth larch 720 mm/a,half-mature larch 751 mm/a,young growth Korean pine 762 mm/a,half- mature Korean pine 826 mm/a,oak 677 mm/a,weed tree 741 mm/a.The most important factor effecting the evapo- ration was litter on the forest ground and there existed negative correlation between evaporation and covering.Evap- oration occurred dominantly in the surface soil with the depth of 20 cm.Significaht differences exsited in the a- mount of evaporation among differences forest tepys.
