摘要
为能在只具备单木和林分年龄、胸径的情况下预估生长量,分别以湿地松单木、林分为建模对象,应用改进单纯形法和TOPSIS法探索以单木、林分的年龄、胸径特征因子为辅助变量来建立单木、林分材积生长率模型的建模方法,编制湿地松单木、林分材积生长率表,为森林资源档案管理中小班生长量预测和数据更新提供科学依据。
In order to estimate the growth at the age and DBH of a single tree and stand, single tree and stand of Pinus elliottii were used as modeling objects, using the improved simplex method and TOPSIS method to explore the modeling method with single tree and stand age, DBH factors as auxiliary variables to establish the individual tree and stand volume growth rate model, volume growth rate table of single tree and stand of Pinus elliottii was compiled, which provided scientific basis for prediction and data update of growth rate for small class in forest resources archives management.
