| 摘 要： | 依据湖南省碳汇林的主要类型,利用"八五"到"十二五"期间课题组自有研究成果,并进行补充调查;以碳汇林的17个主要建群种作为研究对象,综合考虑林分类型、立地状况、群落结构等因子布设固定样地194个,按径阶组划分不同的树高级用以选取目标径阶标准样木共计1 098个,采用树干解析木法,利用Richard、Logistic、Korf、Mitscherlich、Schumacher、Weibull等6种理论生长方程分别进行拟合。得出拟合效果最优的主要建群种树高和胸径生长模型,所有最优模型相关系数均达到了0.9以上,通过评价与检验,各模型均具有较好的拟合精度和预估水平。

| Abstract: | Based on main types of project forests of project forest of Carbon Sink in Hunan Province,making full use of own achievements of the studying team between the Eighth and Twelfth Five-year Plan period,meanwhile carrying out the supplemental investigation,taking 17 main constructive species as research objects,194 typical sample plots were set up according to the stand type,site conditions,community structure.1 098 goal diameter-class standard trees were selected according to diameter-class groups of different tree-height grades. The optimal fitting models of tree height and DBH growth of main constructive species were obtained by stem analysis using Richard,Logistic,Korf,Mitscherlich,Schumacher, Weibull theoretical growth equations. The correlation coefficient of all optimal fitting models reached above 0.9.Through the evaluation and test,the optimal fitting models possesses rather good fitting precision and forecast dependability. |
