在林分直径分布转移矩阵模型的基础上 ,用多目标规划建立同龄林直径分布优化调整模型。将林分密度最优控制模型引入保留密度约束 ,将正态分布的概率密度函数引入直径分布状态约束 ,实现以总体密度优化控制径级分布优化。在分布状态约束和疏伐径级约束中引入偏差变量 ,按目标约束处理 ,更适合于实际 ,更有利于调整目标的实现。
Based on the model of distribution of translocation of diameter distribution, a multi-objective programming model was established to optimize the diameter distribution of the same age. The optimal stand model of stand density was introduced into the constraint of reserve density, and the probability density function of normal distribution was introduced into the constraint of the diameter distribution to optimize the size distribution optimization with the overall density. The introduction of deviation variables into the distribution state constraints and the sparse-diameter constraints can be more suitable for reality and more conducive to the realization of the target according to the target constraint.
