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.

通过实地观测，分析了毛竹林在涵养水源、保持水土、净化降水等方面的作用。结果表明：与其它林分相比，林冠截留损失减少约10%，蒸腾量增加约12%，蒸散量基本相同;地表径流频繁发生，地表径流比（0. 6~35岁。3）K+、Cl-、SO2的淋失量较高。
