摘要: 燕山东段森林群落枯落物现存量平均为4.35~28.67t/hm~2,以山杨混交林、松栎混交林、椴树混交林最高,栎林和油松林次之,侧柏林最低.灌木群落枯落物现存量平均为4.15~18.94t/hm~2,低于森林群落.森林枯落物现存量受树种组成、年龄、立地条件及人为干扰的影响.其中,人为干扰影响最大,几乎使枯落物损失殆尽.森林枯落物营养元素总贮量0.176~1.534t/hm~2,最大贮水量3.9~54.0t/hm~2,平均41.2t/hm~2;灌木群落枯落物营养元素总贮量0.327~0.846t/hm~2,最大贮水量为4.8~26.9t/hm~2,平均16.2t/hm~2.
英文摘要: The average amount of the present remaining litter in the forest community of the Eastern Yanshan Mountain is 4.35~28.67t/ha, with the greatest amount in the mixed forests of aspen (Populus davidiana Dode) with other broadleaf trees, the mixed forests of Chinese pine (Pinus tablaeformis Carr.) with oak, and the mixed forests of linden with other broadleaf trees; with the greater amount in the oak (Quercus variabilis B1., Q. liaotungensis Koidz., Q. dentata Thunb.) and Chinese arborvitae (Platy-cladus orient...
