This study discuss about the problem within timber management, biomass and carbon sequestration of Cunninghamia lanceolata plantation. The content include diameter distribution, simulation individual tree growth model, the relationship between biomass and D.B.H., Carbon content of different position and the analysis of C/N and create an interrelated function. This data can provide with concrete information for forest management .
Data of this study were collected from China-fir plantation on Pa-Hsien-Shan working circle and Shyr-Wen-Shi demonstration zone. The stand is arrived at rotation age, and we hope to understand the growth of stand by the individual tree's data. The summary of obtained result is as follows :
Diameter distribution of China-fir plantation is fitted by three-parameter Weibull distribution. Basal area growth and volume growth is fitted by Richards growth model.We used Mitscherlich to fit height growth. It means that basal area growth, volume growth and height growth should choose different kinds of model to simulation.
The dry weight of branch, stem, and above-ground all increase with DBH. The proportion of the biomass of branch and leaf is decreased with the increase in age, but the opposite is true for the biomass of stem.
Carbon sequestration on different diameter and different portion all have significance, it means that when estimate the carbon sequestration in stand, stem, branch and leaf should calculate individually.
The results will provide detailed information for China-fir plantation.
