| 摘 要： | 本文对海南岛尖峰岭热带山地雨林及其更新群落的凋落物产量动态、各组分的季节变化规律及凋落物贮量进行了研究，分析比较了这两个林分的凋落节律的异同，并对凋落枝的收集方法进行了对比。本文指出：“双凋落峰”和“由于台风影响而产生大量非正常凋落物”是尖峰岭热带森林的两个重要的凋落特征。本项研究对深入了解热带林生态系统的功能、对热带森林资源的保护和永续利用均有重要意义。

| Abstract: | We compared the dynamics of litter production and storage in the natural tropical montane rain forest with that of a regenerated forest after clear cutting at Jianfengling, Hainan Island, and studied the effect of typhoon on litter production.The mean annual litterfall (D. W) in the tropical montane rain forest was 9.177t·ha-1, of which the leaves, branches, and flowers and other mixed matter accounted for 49.6%, 37.0% and 13.4%,respectively. The annual litterfall in the regenerated forest was 9.323t·ha-1 with the leaves, branches, and flowers and other mixed matter occupying 56.2% , 33.0%, and 10.8%, respectively, of the total litterfall. The storage of litterfall in both of the two forest types was 5.9t·ha-1.A double falling peak and extremely high percentage of litterfall caused by typhoon are characteristic of the litter production in the tropical forest at the Jianfengling area. In some years, the typhoon-induced litterfall accounted for over 40% of the total litter production, illustrating that the effect of typhoon on tropiacl montane rain forest ecosystems is frequent, large and farreaching. |
