通过对６６块间伐试验样地资料各项指标与间伐强度相互关系的分析，采用数学模拟的方法，分别建立了各种预测模型。解决了如何由间伐强度和伐前林分状态，准确推算间伐木的平均高、平均胸径和间伐后林分的平均高、平均胸径及Ⅰ、Ⅱ、Ⅲ级木伐前、伐后的变化，解决了如何进行间伐修正。从数字上直观的反映了不同间伐强度的马尾松林分结构的动态变化。
Based on the analysis of the relationship between each index and the thinning intensity of the data of 66 thinning plots, mathematical models were used to establish various prediction models. The method solves the problem of how to predict the average height and average diameter at the middle of the thinning logs and the average height and the average diameter of the stand after the thinning and the changes of the grade Ⅰ, Solved how to carry out thinning correction. The dynamic changes of Pinus massoniana stand structure reflecting the different thinning intensity are numerically and intuitively reflected.
