摘要
在全面系统收集秃杉人工林资料的基础上,采用SPSS软件整理、分析、辨别、筛选秃杉人工林的年龄与优势平均胸径、优势平均高的有效数据,用于秃杉人工林立地指数回归分析--导向曲线数学模型的建立和按照编制秃杉人工林立地指数的有关要求进行相关数据的整理、分析、计算,依据其整理、分析、计算,再对其结果进行秃杉人工林立地指数的编制。
In the overall system to collect Taiwania flousana ganssen plantation material, and on the basis of using SPSS software arrangement, analysis, distinguish, screening Taiwania fousana ganssen plantation age and the advantages of the average diameter at breast height, average high effective data advantage, Site index Taiwania flousana ganssen plantation for regression analysis-oriented curve establishing mathematics model and,Site index of Taiwania flousana ganssen of plantation in accordance with the relevant requirement of related data sorted, analysis and computation, According to the arrangement, analysis, calculation results of the index of Taiwania flousana Ganssen plantation.
