| 摘 要： | 主要讨论武夷山先峰岭５１龄甜槠群落的生物量和生产力．测定结果表明：１９９２年１２月甜槠群落的现存生物量为４０７２８．１ｇ／ｍ２，其中地上部为３５０８２．０ｇ／ｍ２，占总量的８６．１４％，地下部为５６４６．１ｇ／ｍ２，占１３．８６％．甜槠群落１９９２年的净初级生产量为１３８１．６ｇ／ｍ２·ａ，其中凋落物产量为３７９．２０ｇ／ｍ２·ａ，占净初级生产量的２７．４５％．而用于植物自身生长的存留量为１００２．４ｇ／ｍ２·ａ，占７２．５５％．甜槠群落的生物量累积比为２９．４８，已达成熟林的比率关系．

| Abstract: | This paper deals mainly with the biomass and productivity of a 51-year-old Castanopsis eyrei community in xian fen Ling of wuyi mountains. The main results of the measurements were as follows: 1 )The standing crop of this community (1992) was 40 728. 1 g/m2;in which the biomass of aboveground was 35 082. 0 g/m2; 86. 14 Percentage to total; and the biomass of underground was 5646. 1 g/m2; i. e. 13. 86%. 2). The net primary production of this community in 1992 was 1 381. 6 g/m2. a;In which the Litter fall was 379. 20 g/m2. a; made up 27. 45%;and the retention for the growth themselves was 1 002. 4 g/m2. a;accounting for 72. 55 %. The ratio of Biomass accumulation was 29. 48;which was up to the ratio of the mature forest. |
