| 摘 要： | 对北京西山林场、妙峰山和申家沟3处的7种林分的持水性能进行研究测定，结果表明：枯落物的总蓄积量在1．49～10．08t／hm2，其中刺槐麻栎混交林的最高，黄荆纯林最小。枯落物未分解层、半分解层吸水率与浸水时间关系式为：=Aln（t）＋，不同林分枯落物未分解层、半分解层吸水率与浸水时间之间表现出较好的相关性，

| Abstract: | Water-holding capacity of 7 types forest stand in Xishan Plantation,Miaofeng Mountain and Shenjiagou Village of Beijing were determined.The results showed that litter extant quantity ranges from 1.49 to 10.08 t/hm2.Among which,R.pseudoacacia L.and Q.variabilis Carr.mixed forest was the highest and V.negundo L.was the lowest.The relationship of 7 different forest stand types of un-decomposed litter and half-decomposed litter of water absorption and immersion time was W = Aln(t)+ B,and showed good correlation... |
