通过对泰山9种代表性林分的水源涵养能力的分析评价,结果表明,林冠截留能力最大的是五角枫纯林,最小的是黑松纯林;枯落物有效持水能力最大的是麻栎×黑松林,最小的是黑松纯林;土壤贮水能力最大的是50年生麻栎纯林,最小的是黄连木纯林。综合比较9个林分的水源涵养能力,其从大到小的顺序是:五角枫、50年生麻栎、15年生麻栎、麻栎×黑松、侧柏、刺槐、黄连木×刺槐、黑松、黄连木。

Through analyzing and evaluating the water conservation ability of nine representative stands in Mount Tai, the results showed that the canopy retention capacity was the largest in pure canopy forests and the smallest was the pure stands of Pinus thunbergii. The litter Quercus × ​​black pine forest, the smallest is the pure Pinus thunbergii; soil water storage capacity is the largest pure 50-year-old Quercus liaotungensis, the smallest is the Pistacia pure wood. Comprehensive comparison of water conservation capacity of nine stands, the order from big to small is: Pentagon maple, 50-year-old Quercus, 15-year-old Quercus, Quercus × ​​black pine, Platycladus orientalis, Pistacia chinensis × black locust, black Pine, Pistacia wood.
