对日本中部京都县南部阔叶次生林的地上生物量和净初级生产力进行了估算。在研究区附近采集了46株3cm胸径的乔木和灌木样方、11株1cm胸径<3cm的灌木样方和24株藤本样方，建立了树干、枝叶干重与尺寸参数之间的异速生长关系。对研究区的所有乔木、灌木和藤本植物（1cm胸径）进行了胸径普查。根据异速生长关系和胸径普查计算的地上生物量为105.05 t ha-1。乔木和灌木（3cm胸径）占总生物量的92.2%。所有乔木和灌木的地上净初级生产量估计为15.84 t ha-1 yr-1，其中94.0%为乔木和灌木（3cm胸径）。
Aboveground biomass and net primary production were estimated in a broad-leaved secondary forest in the southern part of Kyoto Prefecture, central Japan. Forty-six sample trees and shrubs (3cm≦diameter at breast height (DBH) ), 11 sample shrubs (1cm≦DBH<3cm) and 24 sample lianas were cut near the study site to establish allometric relationships between size parameters and dry weights of stems, branches and leaves. DBH census was made for all trees, shrubs and lianas (1cm≦DBH) in the study site. The calculated aboveground biomass based on the allometric relationships and the DBH census was 105.05 t ha-1. Trees and shrubs (3cm≦DBH) occupied 92.2% of the total biomass. The aboveground net primary production for all trees and shrubs was estimated to be 15.84 t ha-1 yr-1, of which 94.0% as in the trees and shrubs (3cm≦DBH).
