摘　　要：以鼎湖山森林演替的空间系列及黑石顶天然次生林为研究对象，探讨了南亚热带森林群落生物量和生产力动态特征。研究结果表明，随着演替进程的发展，群落的生物量不断积累，但生物量的各用份的动态趋向并不一致，其中叶生物量的最高值出现在演替的中后期．在演替过程中生产力的动态与生物量变化相一致，随着演替的进展第一性生产力不断增加，但演替过程生产力的发展速率不是均匀的，生产力在群落的演变前期发展较侠，在中、后期则发展较慢。Basing on the spatial sere of Dinghushan forest and a natural secondary forest inHeishiding,features of biomass and productivity dynamics in successional process of Low Subtropi-cal forest have been studied.The results show that:Community biomass is unceasingly accumulating in the process of succession.However,biomass dynamics of each component part are different.For example,leaf biomass in highest inpro-middle stage but in climax stage. The productivity dynamics is consistent with the change ofbiomass.Primary productivity is increasing continuously in the successional proces with unevenvelocity;Productivity grow faster in former stage and slower in middle.and later stages.
