Does bamboo forest harm the functions of recharging water resources and conserving soil and water?

在实地测量的基础上，分析了毛竹林在补给水资源、保持水土和净化降水等方面的作用。结果表明：与其他森林相比，1)截留损失少10%左右，蒸腾量大12%左右，因此蒸散量基本相同；2)地表径流频繁发生，但地表径流比(0。6 ~ 35。3)林冠中K+、Cl-、SO2的淋失量相当高。

The effects of Moso-Bamboo(Phyllostachys pubescens) forest on the functions of recharging water resources, conserving soil and water, and purifying precipitation were analyzed based on the in-situ measurements. The results indicate that comparing with other forests, 1) interception loss was about 10% less but transpiration was about 12% larger and thus evapotranspiration was almost the same, 2) surface runoff frequently occurred but the surface runoff ratios(0. 6~ 35. 5%) were relatively small, and 3) leaching of K+, Cl-, SO2 from the canopy was considerably high.
