摘要
根据湖南会同生态站１０ａ的定位实测数据，对第二代杉木人工林的生物量进行了研究．结果表明：第二代１０年生杉木林的生物量为６３．８３ｔ·ｈｍ－２，年净生产力为１０．９１ｔ·ｈｍ－２，干和根的增长幅度大体持平；生态系统生物量分配为乔木层＞草本层＞灌木层＞死地被物层．该项研究可为杉木连栽造成的影响提供基础数据．
Based on ten years' data obtained from the Huitong Forest Ecology Research Station, the biomass of a second generation Chinese fir plantation is studied. The results show that the biomass of the 10 year old Chinese fir stand is 63.82 t/hm 2, while its net productivity is 10.91 t/hm 2·a. The increment rato of the trunk is almost the same as that of the root. The biomass distribution order of the ecosystem is tree layer>herb stratum>shrub stratum>dead litter. The study can provide some basic data for successive cultivation of Chinese fir plantations.
