摘要
主要讨论了武夷山先峰岭甜槠（Ｃａｓｔａｎｏｐｓｉｓｅｙｒｅｉ）群落１９９２～１９９５年４年凋落物的产量和季节动态．甜槠群落１９９２～１９９５年的凋落物产量分别为５５６．２６、３７９．２０、３６４．３５、２５８．７０ｇ／ｍ２，凋落物量呈现逐年下降的趋势；４年的平均值为３８９．６３ｇ／ｍ２，４年中的最高值与最低值之比为２．１５∶１．１９９３年营养元素通过凋落物的归还量分别为：Ｎ３．６４５、Ｐ０．１３９、Ｋ１．２８２、Ｎａ０．０５７、Ｃａ２．６２３、Ｍｇ０．５４８ｇ／ｍ２．
This paper was a part of researches on forest ecosystems in Wuyi mountains. It dealt mainly with the dynamics and production of litter falls of Castanopsis eyrei community at xiangfengling of Wuyi mountains over a four year period of 1992￣1995. The production of litter falls of Castanopsis eyrei community from 1992 to 1995 was 556.26, 379.20, 364.35 and 258.70 g/m 2 respectively. The average annual litter production from 1992 to 1995 was 389.63 g/m 2; the ratio of the litter production in 1992 (highest)to that in 1995 (lowest)was 2.15 ∶1, litter production decreased gradually during those four years. The return of elements through litter falls in 1993 was 3.645g/m 2 for N, 0.139 g/m 2 for P, 1.282 g/m 2 for K, 0.057 g/m 2 for Na, 2.623 g/m 2 for Ca, 0.548 g/m 2 for Mg, respectively.
