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（－１））．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．Seasonal and spatial dynamics of above- and underground biomass of Misothus sinensiscommunity are studied.The results show that its aboveground biomass is maximum inthe second ten days of August 1 and its underground one is minimum during reviving andmaximum during withering period, which is related to the developmental stage and thetransport of substances.
