| 摘 要： | 以闽东柳杉人工林为研究对象，研究31年生柳杉人工林不同经营密度与生长之间的关系规律，具体探讨了不同密度与林分平均胸径、树高、立木单株材积、优势高以及蓄积量之间的相关关系．对一系列不同的生产模型，采用单纯形法等数学方法进行拟合，选择出存在显著或者极显著关系的模型，并且从中寻求适合于闽东地区柳杉人工林生长的最优生产模型，从而为当地林业生产中的密度管理和林分生产力的预测提供科学的理论依据。

| Abstract: | Base on the data collected from sample plots in Eastern Fujian, the relationship between average stand volume, VIS, height, dominant height, DHB and stand density of Cryptomeria fortunei plantation of 31 years old were studied through a series of mathematical models. The results show that significant correlation exsits among all factors, and there are some better models that are suitable for describing the stand growth of Cryptomeria fortunei plantation in Eastern Fujian . So they could be used to conduct forest production such as thinning for Cryptomeria fortunei plantation and estimation of productivity and so on. |
