区域承载力与承载状况的定量描述

(1)   状态空间的概念模型:

 

式中, 为区域承载力值(regional carrying capacity)的大小; 为代表区域承载力的有向矢量的模数; 为区域人类活动与资源环境处于理想状态是在状态空间中的坐标值 

(2)   区域承载力的数学表达式:

 

式中,  轴的权重。

(3)   区域承载状况的计算公式:

 

式中, 为显示的区域承载状况(regional carrying state); 为区域承载力; 为显示的区域承载状况矢量与该资源环境承载体组合状态下的区域承载力矢量之间的夹角,其计算公式可可表达为   分别代表状态空间中的2个向量,假设其顶点分别为    则代表顶点 , 在状态空间中的坐标值  为代表状态空间的维数。

(4)   对夹角 的符号及显示的区域承载状况与区域承载力关系:

 

式中, 表示显示的区域承载力矢量的模; 表示理想状态时的区域承载力矢量的模; 为两者的夹角。
