| 摘 要： | 通过对几种不同树种叶片枯落物蓄水性能研究结果表明：慈竹、刺槐、三角槭、青桐的最大持水率均较大,其次为榆树、枫香、构树、二球悬铃木等,其它树种则较小。另外不同树种叶片枯落物吸水速度存在一定的差异,但均表现出相同的趋势,随着吸水时间的不断增加,不同时段的吸水速度逐渐减小并趋近于零,且不同时段的吸水速率均可以利用幂函数回归方程进行估测。

| Abstract: | The results of leaf litters of several different tree species showed that： the maximum water-holding proportion of N.affinis（Rendle）Keng f.,Robinia pseudoacacia L,Acer buergerianum Miq.,Firmiana simplex（L.）W.F.Wight were greater,followed by Ulmus pumila L.,Liquidambar formosana Hance,Broussonetia papyrifera,Platanus×acerifolia（Ait.） Willd.,and other species is small.in addition,there are some differences between water absorption rate of leaf litters of the different tree species,but all show the same trend,the speed of the water decreases at different times and tends to 0 with the increasing of water Time,and the power function regression equation can be used to estimate the water absorption rate of different periods. |
