| 采用数量化理论方法,运用数理统计软件计算影响筇竹生长的立地因子的贡献值及筇竹高度
预测值,以示性函数将各环境因素数量化,将影响筇竹生长的立地因子划分为7个项目24个类目,采用回归分析方法建立多元回归方程,计算出各类目相应的数值,进行立地质量等级评价。结果表
明,筇竹高度预测值分别为:6.07~5.00、5.00~3.93、3.93~2.87、2.87~1.80、<1.80 m;在随机抽取的30块样地中11 块立地质量等级为“优”,11块为“良”,8块为“合格”,占筇竹样地总数的93.33%,合格率较高,区域生境是筇竹的适生区域。筇竹生长地立地质量得分表经复相关系数F检验及适合显著性检验均达到了精度要求,适用于筇竹林分立地质量评价。 |
| 英文摘要: |
| Using quantitative theory methods and mathematical statistical software, the contribution values
of site factors affecting the growth of Qiongzhuea tumidinodaand the predicted values of bamboo
height were calculated. The environmental factors were quantified using a graphical function, and the site
factors affecting the growth of bamboo were divided into 7 items and 24 categories. Regression analysis
was used to establish multiple regression equations, calculate the corresponding values for each category,
and evaluate the site quality level. The results showed that the predicted heights of Qiongzhuea tumidinoda
were 6.07-5.00, 5.00-3.93, 3.93-2.87, 2.87-1.80, and <1.80 m, respectively; among the 30
randomly selected plots, 11 plots were “excellent”, 11 plots were “good”, and 8 plots were “qualified”,
accounting for 93. 33% of the total plots. The qualification rate was relatively high, and the regional
habitat was the suitable habitat for Qiongzhuea tumidinoda. The site quality score table for the growth site of Qiongzhuea tumidinoda forests met the accuracy requirements through the F-test of multiple
correlation coefficients and the suitability significance test, which was suitable for evaluating the site quality
of Qiongzhuea tumidinoda forests. |
