福建柏人工林合理经营密度及其应用研究

Studies on the Ratinoal Management Density of Fokienia hodginsii Plantation and Its Application

根据福建省福建柏分布区调查的１２０５个冠幅与胸径成对值，建立福建柏冠幅与胸径的数学模型以及林分最大密度与胸径的数学模型，进而应用半峰宽公式计算合理经营密度，其结果为：最大密度模型的合理经营密度为０．６４－０．９３；并介绍了合理经营密度的应用方法。

The mathematical model of crown width and dbh and the mathematical model of maximal standdensity and dbh of Fokienia hodginsii were established based on the 1205 paired values of crown width anddbh obtained by the survey of F，hodginsii distribution areas in Fujian Province. Further the rationalmanagement density of F. hodginsii plantation was calculated using the formula of peak width at half-heightand the result showed that the rational management density of the maximal density model was 0．64－0．93．Inaddition，the application method of rational management density was also introduced in this article.
