前言曾报导林分中三株最高树的平均高与蓄积量的相关关系,比优势树种的平均高与蓄积量的相关关系更为紧密。在实际应用上,曾在编制航空象片立木材积表时,在象片样地内量测三株最高树的象片观测值,作为一个自变量用复回归分析法建立回归方程。至于这个理论在森林地面样地调查作业方面,以及有关这方面的实验数据,却没有看到更多的报导。 Foreword It has been reported that the correlation between the average height and stock volume of the three highest trees in the stand is more closely related to the average height and stock volume of dominant species. In practical application, the observations of the image of the three highest trees in the sample plots have been used in the compilation of aeronautical photo albums as an independent variable to establish the regression equation by complex regression analysis. There is no further report on this theory in the field survey of forest land samples and the experimental data in this respect.
