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 productivity of Gongba Mountain Brassica oleracea, Betula platyphylla, Hemlock, Maple, Betula platyphylla, Abies fabri I, Emeian Abies chensiensis II and Scylla serrata were studied. Their biomass was 220.082 t · hm-2,568.008 t · hm-2,544.519 t · hm-2,282.558 t · hm-2 and 279.819 t · hm-2, respectively; their productivity was Is 9.962 t · hm-2 · a-1, 10.067 t · hm-2 · a-1, 12.936 t · hm-2 · a-1,4.692 t · hm-2 · a-1 and 1 .389t · hm-2 · a-1. Through the correlation analysis of forest biomass and productivity and ecological factors in Gongga Mountain, it is shown that annual precipitation is the dominant factor restricting forest biomass and productivity.
