| 摘 要： | 根据闽北地区杉木丰产林110块样地的经营密度,应用半峰宽公式计算其合理经营密度。结果表明,最大密度模型的合理经营密度为0.64～0.88,最大密度线模型的合理经营密度为0.62～0.89;两种模型的经营密度经u检验表明没有显著差异;符号检验结果表明,两者的合理经营密度都适用于闽北地区杉木人工林的林分密度管理。

| Abstract: | This paper presents a new method of obtaining the optimal density for management (ODM ). According to the density for management from a lot of high-yield plantations, the way of obtaining ODM by using the formula of peak width at half height ( PWH ) is fast and economical as well as most representative. 110 sam-plesplots were calculated from the high-yield China fir plantations in North Fujian. The results are as forllows:
1)The ODM of Maximum Density Model is 0.64-0.88;2) The ODM of Maximum Density Line Model is 0.62-0.89;3 ) U-test shows there is not remarkable difference between the densities of mana-gement of the above models;4 ) Sign test shows both two ODMs are suitable for stand density for managementof China fir plantations in North Fujian. |
