| 摘 要： | 根据对蔡家川流域30块油松标准地的调查资料,对油松林木生物量进行了研究。结果表明:胸径能够较好地用于全株、树干和树枝的生物量测定,建立了以胸径为基础的林木全株及器官生物量估测模型;平均生物量表现为树干>树枝>树叶,树干平均值为63.82%,树枝平均值为26.47%,树叶平均值为9.72%;坡向影响油松地上部分总生物量,并且影响地上部分生物量的分配;冠幅面积对油松整株、树干、树枝、树叶生物量和树高胸径均有影响:树冠冠幅面积每增加1 m2,整株生物量增加1.842 kg、干生物量增加0.941 kg、枝生物量增加0.704 kg、叶生物量增加0.196 kg;树冠冠幅面积每增加1m2,胸径增加0.149 cm、树高增加0.08m;油松树冠冠幅面积对油松器官生物量分配无影响。

| Abstract: | Based on the survey of 30 Standard-plots in CaiJiachuan River basin,the biomass of Pinus tabulaeform was studied.The results of the study showed as following: Diameter at breast height(DBH) can be better used for the measurement of biomass of the whole plant,stem and branches,then built biomass estimation models of the whole plant and organ based on DBH.The average biomass of different parts of Pinus tabulaeform were: stem’> branches’ > leaves’.Of which,the average biomass of stem was 63.82%,the average biomass of branch was 26.47%,the average biomass of leaves was 9.72%.Slope aspects affected the aboveground total biomass,also affected the distribution of aboveground biomass.Pinus tabulaeformis’ crown width area had effect on the biomass of the whole plant、stem,branches,leaves,tree height and DBH: As the crown width area increased by 1㎡,the biomass of the whole plant increased 1.842 kg,biomass of the trunk increased 0.941 kg,biomass of the branch increase 0.704 kg,biomass of the leaves increased 0.196 kg;The DBH increased 0.149cm and the height of trees increase 0.08 m,while the crown width area increased by 1 m2.Pinus tabulaeformis’ crown width area had no effect on organ biomass distribution. |
