马尾松人工林相对树高曲线模型及其应用研究

利用标准地调查数据 ,建立马尾松人工林相对树高曲线模型 ,结合二元材积表测算标准地蓄积量。误差分析表明 :应用相对树高曲线模型测定林分蓄积量 ,精度高于一元材积表 ,可达到接近用二元材积表的测算水平 ,且不增加野外调查工作量 ,在实践上有一定应用价值。

Studies on the Relative Height Curve Models of Pinus massoniana Plantations and on Their Application

The sample plot survey data were used to establish the relative height curve models of Pinus massoniana plantations to guess and estimate the sample plot stocking in combination with the binary volume table.The error analysis indicates that the precision of applying the relative height curve models to determine stand stocking is higher than that of applying the unitary volume table and is close to the guess and estimate level of the binary volume table and therefore they possess the certain applied value in practice.
