资源动力学模型

 

(1) 开发之后的剩余资源种群个体数量为:

式中,为时间t的种群个体数量;为时间t的收获量;α为资源单位面积生物量中,从收获物中以残遗种保护区形式扣除之后的部分;r为内在增长率。

(2) 当残遗种保护区被引入的时候,为了得到不变的收获量,平衡生物量会达到下面的值:

使收获量最大的残遗种保护区面积是:

最大收获量为:

(3) 可变的收获策略:

 为了使系统更快趋向于极值,可变的收获策略如下:

式中,E为收获量;H为收获,ε为控制的力度。

一种离散的表示为:

通过改变收获量,决策规则被改变了。

残遗种保护区面积的改变如下:

式中,s是额外的控制力参数。
