| 摘 要： | 在云南元谋干热河谷区,选择坡改梯经济林、冲沟内生态林和沟头坡面生态林3种典型植被恢复模式,分别设置标准观测小区,在雨季观测这3种模式与其对照（未种植任何植被）的水土流失、土壤入渗率和0～100 cm内的土壤剖面水分动态。结果表明,生态林和经济林植被恢复模式较其对照分别减少了水土流失30%和60%以上,显示出极显著的控制水土流失的效应。植被恢复还极显著增加了土壤的入渗率（可增加100%～200%）。在雨季,生态林和经济林植被恢复模式,较其对照分别显著增加了土壤含水量30%和100%以上,说明植被恢复在雨季不会导致土壤旱化,因为植被恢复减少了地表水和土壤细颗粒的流失,同时还增加了降水的入渗,这2个作用都使土壤整个剖面水分含量增加。

| Abstract: | In Yuanmou dry-hot valley of Yunnan Province,three typical vegetation restoration patterns including production forest transformed from sloping fields to terracing,ecological afforestation within the gully and ecological aforestation in gully head and slope were selected to compare its effects of soil and water conservation.Soil and water loss,soil infiltration rate and the soil moisture dynamics of soil profile with the depth of 0-100 cm of these three patterns and their controls were observed by establish... |
