本文探讨鼎湖山季风常绿阔叶林调落物养分特征，分析了其动态、季节间与种间变异、构成特征等。结果表明，该群落各种群含氮量的季节变化较小，各个种的变异系数多在15％以下，但磷、钾和钠的变异较大。无论在群落还是在种的水平上，各种营养成份间均没有显著的相关性。除磷外，不同种问养分含量有显著差异，季节间则除镁外无显著差异，磷在红壤地区土壤中难于利用的主要原因可能是不同植物在磷的利用上趋同．全年通过凋落物回归土壤的养分量为氮99．88kghm-2，磷15．03kghm-2．钾27．01kghm-2，钙37．11kghm-2；镁12．19kghm-2。在该群落中，椎栗是对落叶养分贡献最大的种，荷木其次。8月是当年凋落物养分量最高的月份，主要是由于台风作用产生大量的枝叶折落，12月则是最低月份，两者在构成上的主要区别是8月份枝条所持养分量极大，而12月份枝条极少。全年凋落物养分出现两次高峰，4月和8月，而以较寒冷的1、2、11、12月份最低。 In this paper, the nutrient characteristics of the seasonal monsoon evergreen broad-leaved forest in Dinghushan were studied, and its dynamics, seasons and interspecific variation were analyzed. The results showed that the seasonal variation of nitrogen content of all species in this community was small, and the variation coefficient of each species was more than 15%, but the variation of phosphorus, potassium and sodium was larger. There was no significant correlation between various nutritional components, whether at the community level or at the species level. In addition to phosphorus, different species of nutrient content were significantly different, except during the season except magnesium was no significant difference in the soil phosphorus red soil difficult to use the main reason may be that different plants in the use of phosphorus convergence. The amount of nutrients returning to the soil through litter in the whole year was 99.88 kghm-2 of nitrogen and 15.03 kghm-2 of phosphorus. Potassium 27.01 kghm-2, calcium 37.11 kghm-2; magnesium 12.19 kghm-2. In this community, the chestnut is the largest contributor to deciduous nutrients, wood second. August is the highest littoral month of the year, mainly due to the typhoon produced a large number of branches and leaves fall, December is the lowest month, the two constitute the main difference is the amount of nutrients held by the branches in August is extremely large, and December branches rarely. In the whole year, the litter nutrient peaked twice in April and August, while it was the coldest in January, February, November and December.
