摘要: 研究了霸王菅群落地上和地下生物量季节和空间变化。结果表明,其地上生物量季节动态较为明显,8月中旬达峰值(1007.40g·m-2).地下生物量在返青期最低,枯黄期最高,这与植物生长发育阶段和物质运转有关。

Abstract: Seasonal and spatial dynamics of above- and underground biomass of Misothus sinensis community are studied.The results show that its aboveground biomass is maximum inthe second ten days of August, and its underground one is minimum during reviving andmaximum during withering period, which is related to the developmental stage and thetransport of substances.
