利用森林水文作用过程分割研究法，对泰山５种林分枯落物和土壤的水文效应进行了研究。结果表明：５种林分枯落物饱和持水量在１２２～５８８ｍｍ之间；土壤总孔隙度在３８５％～６０９％之间；３０ｃｍ厚的土壤饱和持水量在１１５５～１５２７ｍｍ之间，都具有一定的涵养水源能力。以上几个评价涵养水源功能的指标都以阔叶林（麻栎林和竹林）和胡枝子灌木林明显大于针叶林（侧柏和油松）。尤其是灌木林，在涵养水源方面有非常显著和独特的作用。 Hydrological effects of litter and soil in five stands of Taishan Mountain were studied using the method of forest hydrological process segmentation. The results showed that the saturated water holding capacity of the litters in the five stands ranged from 122 to 588 mm. The total soil porosity ranged from 385% to 609%. The soil saturated water holding capacity of 30 cm was 115  5 ~ 152  7mm between, have a certain ability to conserve water. All of the above indexes for evaluating water conservation function are obviously larger than coniferous forests (orientalis and Pinus tabulaeformis) in broadleaf forests (Quercus mongolica and bamboo forests) and Lespedeza shrubs. In particular, shrubs have a very significant and unique role in water conservation.
