摘要
为掌握西南地区云南松林分生长规律,以森林资源连续清查568块固定样地的云南松林分调查数据为基础,系统研究了云南松林分平均树高、林分断面积、林分立地指数、林分蓄积量因子与林分平均年龄、林分优势木平均高、林分公顷株数等的关系,建立了云南松林分断面积生长和林分收获预估模型。模型拟合结果表明,模型具有较高的精确度和稳定性,可应用于西南地区云南松林的经营管理和收获预估。
In order to master the growth rule of Pinus yunnanensis forest in Southwest China,this paper systematically studied the relationships among the average height,basal area,site index,volume factor,average age,average height of dominant trees,and number of trees per hectare,and established the model of stand yield prediction and basal area growth based on the forest inventory data of 568 fixed sample plots.The fitting results showed that the model had high accuracy and stability,which could be applied to the management and prediction of Pinus yunnanensis forest in Southwest China.
