摘要
对10年生马尾松-苦槠混交林和马尾松纯林的水源涵养功能进行比较研究,结果表明:马尾松-苦槠混交林的林分生长量和水源涵养能力在上坡位略低于马尾松纯林,而在中下坡位高于马尾松纯林;两种林分不同层次的持水量均为土壤层>林冠层>枯枝落叶层>林下植被层。土壤层是两种林分类型森林涵养水源功能的主要场所,其饱和持水量占林分总持水量的比例均在98%以上。
Water conservation capacity of a 10 -year- old mixed plantation of Pinus massoniana and Castanopsis sclerophylla and a pure P. massoniana plantation were studied. The results showed that tree growth and stand water conservation capacity of the mixed plantation were slightly lower than those of the pure P. massoniana on the upper slope, but they were higher on the middle and the lower slope. The order of water conservation capacity of different forest components in both of the forest types were soil layer 〉 canopy layer 〉 forest floor 〉 understory. Soil layer was the dominant sector of forest water conservation, and its saturated water capacity made up over 98% of the forest water conservation capacity in both of the forest types.
