摘要
应用贵州铜仁市郊0.67万hm^2光箨篌竹的310株标准竹为材料,分别用眉径(D_(om))、竹高(h_0)、枝下高(h_1)3个指标对经济产量(W_1)和生物产量(W_2)进行数学模型拟合,经过相关系数R和标准差S的比较分析,采用F检验和线性回归相关系数的假设检验,并作模型的实际验证,选出8个较优模型,同时得出径级产量表,这将对光箨篌竹的产量预测有重要参考价值。
Mathematical model fit was made through D.E.H., heighr and clear-bole height of 310 standard Phyllostachys nidularia in 6,700hm^2 forest of Tongren, Guizhou province, After comparative analysis on correlation coefficient and standard deviation, hypothesis testing on F test and linear regression correlation coefficient, real testing on model, 8 better models were selected, meantime, diameter yield table was obtained.
