| 摘 要： | 在不同林龄的杉木人工林中选择不同角规常数进行蓄积调查,以标准地实测调查结果进行对比验证,分析不同角规常数所产生的蓄积调查相对误差,从而确定杉木人工林蓄积测定的最佳角规常数,并以线性回归方程对其误差进行修正以提高调查精度。 |

| Abstract: | Different angle gauge constants are chosen in the Chinese-fir plantation to carry out the investigation of volume and the comparative analysis is conducted according to the actual investigation result of the standard plots.The analysis is done on the relative errors of the volume investigation which are caused by choosing different angle gauge constants to identify the best angle gauge constants of Chinese-fir plantation's volume test,and the regression equation is used to rectify the errors and improve the accuracy. |
| Keywords: | Chinese fir stand volume survey method angle gauge survey |
