摘要
对贡嘎山苞槲柯、香桦林，铁杉、槭、桦杉，峨眉冷杉林Ⅰ，峨眉冷杉林Ⅱ和鳞皮冷杉林的生物量和生产力进行了研究。它们的生物量分别是220．082t·hm-2、568．008t·hm－2、544．519t·hm-2、282．558t·hm-2和279．819t·hm－2；它们的生产力分别是9．962t·hm-2·a-1、10．067t·hm－2·a－1、12．936t·hm-2·a-1、4．692t·hm-2·a-1和1．389t·hm-2·a－1。通过对贡嘎山森林生物量和生产力与生态因素的相关分析表明，年降水量是制约森林生物量和生产力的主导因子。
The biomass and production of five natural forest types were studied in the region on Gongga Mountain in the eastern part of the Tibet Plateau. The forests types studed in the region are: 1) Lithocarpus cleistocarpus ＋ Betula inisignis; 2) Tsuga chinensis＋Acer spp.＋Betula spp.; 3) Abies fabri Ⅰ; 4) A. fabri Ⅱ; 5) and A. squamata. Their total biomass was 220. 082t· hm-2, 568. 008t·hm-2, 544. 519t·hm-2, 282. 558t·hm-2 and 279. 819t·hm-2 respectively and their productivity was: 9. 962t·hm-2·a-1, 10. 067t·hm-2. a-1, 12. 936t ·hm-2. a-1,4. 692t·hm-2·a-1 and 1. 389 t·hm-2·a-1. Analysis of the relationships of biomass and productivity and ecological factors in the five natural forest types indicated that annual precipitation is a dominant factor in this system.
