| 摘 要： | 分析了不同结构落叶松Larix gmelinii天然中龄林的生物量和生产力特征,建立了单株总生物量和干、枝、叶生物量模型。结果表明：①草类＋落叶松林和杜香Ledum palustre＋落叶松林生产力、总生物量及其枝和叶生物量比例均为前者高。总生物量中树干生物量比例为后者高。密度为1 000~3 000株.hm-2,草类＋落叶松林和杜香＋落叶松林生物量及生产力最高分别达55.82 t.hm-2,0.99 t.hm-2.a-1和50.36 t.hm-2,0.83 t.hm-2.a-1。干、枝、叶生物量比例最低分别为79.6%,14.6%,4.8%和83.4%,8.8%,3.6%。②随密度增加,草类＋落叶松林生产力、总生物量及其枝、叶生物量比例均增加,而干生物量比例减小。③随树种组成中落叶松成数的增加,林分生产力、总生物量及其干生物量比例呈增加趋势,而枝、叶生物量比例减小。表5参19 |

| Abstract: | This study analyzed characteristics of biomass and productivity in Larix gmelinii natural forests with different stand structures,and established models for the total biomass and the biomass of trunks,branches and leaves.Results show that:i) As to the productivity,total biomass and biomass proportion of branches and leaves,the grasses + larch forest is higher than the Ledum palustre + larch forest,while for the ratio of the biomass of trunks in the total biomass,the latter is higher than the former.With a d... |
