在湖南省长沙县大山冲省级森林公园内,选择立地条件基本一致的4种森林类型为研究对象,于2011年12月(凋落物高峰期)对森林凋落物现存量及其碳、氮贮量进行调查。结果表明:4种森林凋落物现存量大小依次为青冈-石栎林(12.04±3.60)t·hm~(-2)>马尾松-石栎林(11.65±2.15)t·hm~(-2)>南酸枣林(9.12±2.30)t·hm~(-2)>杉木林(8.92±1.80)t·hm~(-2);凋落叶在凋落物未分解层中所占比例最高,凋落果在4种林分中比例最小(

Four subtropical forests with similar site conditions in the hilly area of Dashanchong Forest Park in central Hunan Province of China were selected to compare the existing litter biomass and its carbon （C） and nitrogen （N） storage. The litters were collected in the peak time of litterfall. Among the four forests, Cyclobalanopsis glauca-Lithocarpus glaber mixed forest had the highest litter biomass （12.04±3.60 t·hm-2）, followed by Pinus massonianaL. glaber mixed forest （11.65±2.15 t·hm-2）, Choerospondias axillaris...
