利用石竹地上部分生物量调查资料 ,探讨各器官平均生物量与胸径、地径、竹高、枝下高的相关关系 ;应用回归分析方法 ,选择不同的回归方程来拟合生物量估测数学模型。结果表明 :以幂函数W =cDaHb 所拟合的生物量估测模型最佳 ,经实用性检验 ,可靠性较高 ,具有很好的实用价值。 Using biomass data from the aboveground part of Dianthus, we discussed the relationship between average biomass and DBH, DBH, bamboo height and branch height. Using regression analysis method, different regression equations were selected to fit the biomass estimation mathematical model . The results showed that the biomass estimation model fitted by the power function W = cDaHb was the best, which was proved to be highly reliable by practicality test and had good practical value.
