摘要
应用粉单竹(Bambusa Chungii)采伐的实测调查数据,通过构建回归模型对粉单竹老竹和新竹胸径—主干材鲜重关系进行模拟。结果表明,曲线模型判定系数较高,达到极显著水平(P<0.01),为粉单竹产量估算提供一个简单实用的测算方法。
The relationship between DBH and bodywood fresh weight was simulated by building regres- sion models through the application of the survey data of Bambusa chungii cutting. The results showed that the determination coefficient of curve model was higher than others. The difference was significant with F test （P 〈 0. 01 ） . A simple and practical calculation method was provided for the estimation of Bambusa chungii production.
