通过对不同地位指数的红皮云杉人工林标准地的统计分析和生长模型的筛选,建立了人工林不同林分(好、中、差)的生长模型。模型的相关系数均达到0.95以上,符合精度要求,适于在生产中应用。
Through the standard statistical analysis and growth model selection of different stands of Picea koraiensis plantations, the growth models of different plantations (good, medium and poor) were established. The correlation coefficients of the model all reach above 0.95, which accords with the precision requirements and is suitable for the application in production.
