摘要
以西丰县郜家店镇不同林龄(18年、22年、38年)的长白落叶松(Larix olgensis)人工林132块样地调查数据为依据,采用正态分布法对林分直径结构和树高结构进行研究,结果表明:正态分布法可以直观反映出林分直径(树高)的分布状态;此方法对该地长白落叶松人工林林分结构的描述效果较好;研究得到的理论参数方程可用于长白落叶松人工林经营管理。
Based on the data of 132 plots of Larix olgensis plantations at different forest ages (18, 22, 38 years) in Gaojiadian Town, Xifeng County, the normal distribution method is used to determine the diameter structure and tree height structure of the stand. The study analyzed the applicability of stand diameter and tree height distribution, and applied the chi-square statistic to test the data fitting curve to predict the distribution of the stand structure. Result shows that the normal distribution method can directly reflect the distribution of the stand diameter (tree height). This kind of description of the stand structure of Larix olgensis plantation in Gaojiadian Town, Xifeng County is optimal. The theoretical parameter equation obtained by the study can be used in the practice of management and management of Larix olgensis plantation, and provides a scientific theoretical basis for rational management of Larix olgensis plantation.
