多种群密度依赖增长模型

在下面的注释中: 指树种;  指树的大小; 指一个时间点。 时刻数目的存量用列向量 表示,它包含种群向量 ,这里 是收割前单位面积 上,种群  时刻存活树木的数量。 表示单位面积 上,种群  时刻砍伐树木的数量。由种群向量 组成的列向量 表示 时刻的收获量。

(1)   整个模型形式如下:

 

式中,  

对于种群 ,其演变可能性形成了一个 矩阵 

 

式中, 是面积 上,种群  时刻存活树木的比例; 是在  时刻,从地块 移动到 上的,原先在面积 上,种群  时刻存活树木的比例。

 

式中, 一个 矩阵,代表在种群 的内向生长中,种群 残存森林储积量的影响。

                                                                                                    

式中, 是一个 列向量,代表种群 的林分无关内向生长。

(2)   树木大小的差异被定义为整个种群平均大小差异的加权平均值:

 

式中, 是在种群 中,地块 上每公顷面积上树木的数量。
