摘要
对海拔１２００—１３００ｍ处的２８年生油松人工林生物量进行了研究。乔木层的生物量采用回归模型预测，其为：油松Ｗ树干＝２．３１６（Ｄ２Ｈ）０．６５８，Ｗ（枝条）＝１．３１３（Ｄ２Ｈ）０．９８９，Ｗ叶子＝１．４１２（Ｄ２Ｈ）０．８３１和Ｗ（根条）＝１．５８９（Ｄ２Ｈ）０．７５３，灌木和草本植物用表测数据计算。结果表明：６月份人工油松林的总生物量为４３．４７０ｇ／ｈａ，其中乔木层３５．６７９吨／公顷，林下灌木及草本层７．７９１ｔ／ｈａ。
The article is about the prelimin research of the plant biomass of 28-aged pine plantation(Pinus tabulaeformis)in the laoding mountain,at an altitude of 1200-1300m,the biomass of tree layer is predi cated by using regression model,they are P.tabulaeforniis W(stem. weight)=2.316(D2H)0.658,W(branchesweight)=1.313(D2H)0.989,W(leaves weight)=1.412(D2H)0.831 and W(roots weight)=1.589(D2H)0.753.the biomass sof shrub and herbs is estimaled by Wtilizing practical measured data in field.Thus,the to tal biomass of the pine plantation was 43.470t/ha including the tree 35.679t/ha,the shrub and herb layer 7.791 t/ha.
