摘　　要：研究与分析了广西九万山自然保护区森林植被在涵养水源方面的生态效益。结果表明,该保护区森林通过林地土壤根际层、枯落物层和林冠层等三个水文层次,贮蓄的雨量为18 368.07×104m3／a,直接或间接带来的生态社会效益价值为2.44亿元;水源涵养效益显著,对维护地方生态安全极为重要。This paper studied the benefit of water conservation of the forest in Jiuwanshan Natural Reserve. The results showed that this forest could conserve a total of water source from precipitation 18 368. 07×104m3·a-1 in three hydrodogical layers-canopy,litter and soil,which values 2. 44×108 yuan ·a-1 accordingly. This indicates that the forest has a notable ecological profit,and it is significantly important for ecological security in the area.
