间作系统中不同种群的共生利益和相互作用模型

(1)  共生利益模型:

 1)竞争损失C可定义为:

                 

 

式中,是复种中树木(或可耕作农作物)的增长, 

单作中树木(或可耕作农作物)的增长。

     2)树木下面资源共享的产量可定义为:

                 

 

式中,是以前森林中的总产量; 是农业森林中树木

的增长。

     3Taxodium ascendens间作系统中全部的相互作用:

               

 

式中,是农作物对树木的全部相互作用; 是肥料的作用,

也就是由于土壤肥力的改进引起树木的产量增加; 是竞争

影响,也就是由于与间作作物竞争光、水和营养引起树木的产量

下降。

     4Taxodium ascendens间作系统中种群动力学的理论框架

表示为:

     

 

 

式中,物种i的生物量;t是时间变量,F是促进收益,M是一个

物种当与其他被管理的物种没有相互作用时的增长。 

     5Taxodium ascendens间作系统中生产动力学的理论框架

表示为:

         

 

式中,是农业森林的生物量生产,S是资源共享时的生产,

在农业森林系统中它在有效利用环境资源方面有相当大的优点

(2)  相互作用模型:

 对于一个三种植物的群落,有:

 

式中,是物种i的大小或密度; 是物种j的大小或密度;

 指单物种i种内竞争的反馈率; 是物种i的承载力; 

是物种ji的竞争系数; 指物种i种内竞争的反馈率; 

是联合影响系数, 是联合影响的反馈率, 指促进系数; 

是促进作用的反馈率。
