摘要
文章系统地分析了中国家温带、温带落叶松林主要群落类型的群落学特征,以及兴安落叶松林、长白落叶松林、华北落叶松林、阿尔泰落叶松林四种森林群落的生物量、年净生产量及其在不同层次上的分配,并探讨了四种森林群落及不同落叶松种群间的干物质累积速率(NP/B)。结果表明:116~130年生的已郁闭的落叶松林群落生物量和乔木层落叶松生物量:华北落叶松混交林为274.89和214.31t/hm2,长白落叶松林250.96和208.66t/hm2,阿尔泰落叶松混交林244.63和202.38t/hm2,兴安落叶松林199.876和182.635t/hm2;年净生产量:华北落叶松混交林为13.82和11.44t/hm2·a,长白落叶松林10.10和9.48t/hm2·a,阿尔泰落叶松混交林9.74和8.21t/hm2·a,兴安落叶松林7.6和7.17t/hm2·a;干物质累积速率落叶松群落及种群为华北落叶松>长白落叶松>阿尔泰落叶松>兴安落叶松。
The sociological characteristic. biomass, productivity, the ratio of productivity and biomass (NP/B) and its distribution in various lapers of the forest dominted by Larix spp. are analyzed.The results show that biomass productivity and NP/B of Larix spp. (116~130a) community are 274. 89t/hm2, 13. 82 t/(hm'· a) and 0. 050 3, respectively of L.principis-rupprechii forest; 250. 96t/hm2, 10. 10 t/(hm2. a) and 0. 0402, respectively of L. olgensis forest; 244. 63t/hm2, 9. 74 t/(hm2. a) and. 0. 039 7 respectiveily of L. sibirica forest; 199. 876 t/hm2, 7. 60 t/(hm2. a) and 0.0380 , respectivily of L.gmelinii forest. The biomass, productivity and NP/B of Larix spp. population are 214. 31 t/hm2, 11. 44 t/(hm2. a) and 0. 053 4, respectively of L.principis-rupprechtii population; 208. 66 t/hm2. 9. 48 t/(hm2. a) and 0. 045 4, respectively of L. olgensis population; 202. 38 t/hm2, 8. 21 t/(hm2. a) and 0. 040 6. respectively of L. Sibirica population; 182. 6 35 t/hm2. 7. 17 t/(hm2. a) and 0. 039 3, respectively of L. gmelinii population.
