| 摘 要： | 对3年生樟树(Cinnamomum camphora)、大叶女贞(Ligustrum Lucidum)、观光木(Tsoongioden-dron odorum)、山杜英(Elaeocar pus sylvestris)、乳源木莲(Manglietia yuyuanensis)和乐昌含笑(Michelia cha pensis)的幼林凋落物持水特性进行了研究.结果表明,各林地的凋落物最大持水量为乳源木莲林地＞乐昌含笑林地＞大叶女贞林地＞观光木林地＞樟树林地＞山杜英林地.林地凋落物的最大持水率呈现观光木林地＞乳源木莲林地＞乐昌含笑林地＞樟树林地＞山杜英林地＞大叶女贞林地.凋落物持水量和浸泡时间的关系及凋落物持水率与浸泡时间的关系按照对数方程变化,凋落物吸水速率与浸泡时间的关系按照负指数方程变化.

| Abstract: | The water holding characteristics of litter in the six young broadleaved stands of Cinnamomum camphora,Ligustrum lucidum,Tsoongiodendron odorum,Elaeocarpus sylvestris,Manglietia yuyuanensis,and Michelia chapensis were studied.By the water holding capacity of litter,the stands was in the order of M.yuyuanensis woodland > M.chapensis woodland > L.lucidum woodland > T.odorum woodland > C.camphora woodland > E.sylvestris woodland.By the proportional water holding capacity as a percentage of the litter dry weigh... |
