摘　　要：不同的林分直径结构可以直接反映林分的生长情况,不仅直观地表达不同树种的直径分布,还可以预测后期林木林分的变化,为主管单位经营森林提供相应的技术依据;本研究利用连续径阶株数之比(P)的变化及负指数对样地中林分各项指标开展分析。从而便于主管经营单位了解各个经营类型中林分直径结构分布的特征,结合相应分析数据拟合出林分的生长规律,为整体森林结构进行全面科学地监测提供科学依据。The different diameter structure of the stand can directly reflect the growth of the stand,not only directly express the diameter distribution of different tree species,but also can predict the change of the stand in the later period.It can also provide the corresponding technical basis for the competent unit to manage the forest.In this study,the change of Q value and negative index were used to further analyze the indicators of the stand in the sample plot.Thus,it is convenient for the competent management unit to directly understand the characteristics of the distribution of the stand diameter structure in each management type,and then to fit the growth law of the stand with the corresponding analysis data,so as to provide a scientific basis for the overall monitoring of the forest structure of the competent management unit.
