| 摘 要： | 采用空间代替时间的方法,通过对黄河小浪底库区不同人工林水土保持效益浅要分析,结果表明:最大吸水率为刺槐>侧柏>20多年生栓皮栎>40多年生栓皮栎,凋落物储量和最大持水量均为20多年生栓皮栎>40多年生栓皮栎>侧柏>刺槐;土壤渗透性能和贮水性能变化较为复杂,侧柏林地的渗透性和贮水性能较其它林地好些,刺槐林地上下层之间变化最大。

| Abstract: | This experiment adopts the method of spatial sequence instead of time successional sequence,studies on soil and water conservation effects of different artificial forest in The Yellow River Xiao langdi reservoir area.The results showed that: Max-water absorption rate in arbor community is as follows: Robinia pseudoacaica> Platycladus orientalis> Quercus variabilis of over 20 years> Quercus variabilis of 40 years.Reserves of litter and Max-water conservation capacity is: Quercus variabilis of over 20 years> Quercus variabilis of 40 years> Platycladus orientalis> Robinia pseudoacaica.changes of soil permeability and water maintaining capacity are complex,and the soil permeability and water maintaining capacity of Platycladus orientalis are relatively well.The soil permeability and water maintaining capacityof Robinia pseudoacaica are relatively high in the topsoil,but the lowest in the substrate. |
