在麻栎、油松、及其混交林中，通过典型样地调查，测定了枯落物的生物量、持水性能和养分元素含量。结果是：天然林各类型枯落物生物量在１０．２２～１３．８９ｔ／ｈｍ２之间，差异甚小；油松人工林最高，为２３．６７ｔ／ｈｍ２。净拦蓄量以麻栎林最高，为３０．６２ｔ／ｈｍ２；松栎混交林次之，为２０．７３ｔ／ｈｍ２；择伐油松林最低，为１３．７７ｔ／ｈｍ２。择伐可使油松林枯落物生物量减少约４１％，净拦蓄量降低约２２％。不同森林类型的枯落物中，养分元素总贮量有很大差异。以松栎混交林最高，为５３２．９２ｋｇ／ｈｍ２；麻栎林次之，为４３４．３１ｋｇ／ｈｍ２；油松林最低，为３８３．８０ｋｇ／ｈｍ２。但各养分元素含量具有很大的一致性，皆为：Ｃａ＞Ｎ＞Ｋ＞Ｍｇ＞Ｐ
In Quercus acutissima, Pinus tabulaeformis and their mixed forest, the litter biomass, water holding capacity and nutrient element content were determined through a typical sample survey. The results are as follows: The biomass of all types of litter in the natural forest ranged from 10.22 to 13.89t / hm2, with a very small difference; the highest in Pinus tabulaeformis plantation was 23.67t / hm2. The net amount of intercropping was the highest in Quercus acutissima forest, 30.62t / hm2; the second in the mixed forest of Quercus rubra was 20.73t / hm2; and the lowest in the selective cutting pine forest was 13.77t / hm2. Selective cutting can reduce the litter biomass of Pinus tabulaeformis forest by about 41% and the net storage capacity by about 22%. Different forest types of litter, the total storage of nutrient elements are very different. In the mixed pine and oak forest, the highest was 532.92kg / hm2, the second was Quercus acutissima forest, which was 434.31kg / hm2, and the lowest was pine forest, which was 383.80kg / hm2. However, the content of nutrients is very consistent, all as follows: Ca> N> K> Mg> P
