摘要
以中国生态系统研究网络长期定位观测的西双版纳热带季节雨林、鼎湖山亚热带常绿阔叶林、哀牢山中山湿性常绿阔叶林和长白山阔叶红松林为基础,分析比较4种森林类型生物量空间分布格局、生物生产力以及物种多样性之间的差异。结果表明,西双版纳总生物量为328.200 t.hm-2,鼎湖山为318.755 t.hm-2,哀牢山为471.608.thm-2,长白山为263.090.thm-2,根生物量约占总生物量的18%-22%;热带亚热带森林的生物量高于温带森林而根冠比(R/S)比小于温带森林,4种森林不同层次间的R/S是草本>灌木>乔木;热带亚热带森林物种丰富度指数和Shannon-W iener多样性指数高于温带森林,均匀度指数则没有明显的变化规律。
Based on the location observation data of Chinese ecosystem research network about the tropical seasonal rain forest in Xishuangbanna, the subtropical evergreen broadleaved forest in Dinghushan Mountain, the moist evergreen broadleaved forest in Ailao Mountain and the broad-leaved Korean pine forest in Changbai Mountain, this paper analyzed and compared the main differences about the spatial distributing pattern of biomass, net primary production and species diversity of four forest types. The results showed that the total biomass was 328.200 t · hm^-2 in Xishuangbanna, 318.755 t · hm^-2 in Dinghushan Mountain, 471.608 t · hm^-2 in Ailao Mountain, 263.090 t · hm^-2 in Chungbai Mountain, the proportion of root biomass was about 18%-22%. The biomass of tropical and subtropical forest was higher than temperate forest, but the R/S was lower than temperate forest. Meanwhile, the R/S was herbage 〉 shrub 〉 tree among different layers. The species richness index and Shannon-Wiener species diversity index in different forest types of tropical and subtropical was higher than temperate forest, while the evenness index has no obvious rules.
