| 摘 要： | 对黄淮海平原农区5,9,11,13年4个不同树龄阶段的杨树人工林生物量和生产力进行了测定和研究,结果表明,生物量依次为16.35,90.49,92.82,127.82 t/hm2;平均净生产力分别为3.27,7.05,8.44,9.83 t/(hm2.a,)各树龄阶段的单木生物量与胸径和树高之间均存在着紧密的相关关系,其生物量分配格局都为树干>树枝>树根>树叶.同时建立了4种龄级杨树人工林及其各器官生物量的回归模型,具有一定的实用价值. |

| Abstract: | This text investigates on biomass and productivity of populus plantation in the Huanghuaihai Plain at different ages of 5,9,11 and 13 years old.The results show that the biomass are 16.35,90.49,92.82,127.82 t/hm2;and their average net-production respectively are 3.27,7.05,8.44,9.83 t /(hm2·a),furthermore,the biomass of single tree has a close correlation to both trunk diameter and tree highness in each age period,and their biomass distributions are:trunk>branch>root>leaves.Meanwhile,the text builds regression equations of populus plantation and different organs biomass which have some applied value. |
| Keywords: | biomass populus Huanghuaihai Plain regression model |
