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。
In different ages of Chinese fir plantation, different horns constant constants were selected for stocking survey, and the results of the survey were compared and verified by standard methods. The relative error of stocking survey by different angle constants was analyzed to determine the most significant Good angle gauge constant, and its linear regression error correction method to improve the accuracy of the survey.
