生态足迹指标的计算与分析模型

   1)种消费项目的人均生态足迹分量的计算公式:

         

 

式中,i为消费项目的类型;为生物生产土地生产第i

消费项目的年(世界)平均产量(); 为第i

消费项目的人均消费量; 为第i种消费项目折算的人均

占有的生物生产面积(人均生态足迹分量)(人); 

为第i种消费项目的年生产量; 为第i种消费项目年进口

量; 为第i种消费项目年出口量;N为人口数。

2)生态足迹的计算:

 1)人均生态足迹为:

     

 

式中, 为人均生态足迹 为均衡因子。

     2)区域总人口的生态足迹为:

                     

 

式中,为总人口的生态足迹N为人口数。

3)生态承载力(生物承载力)的计算:

1)人均生态承载力:

 

 

式中, 为人均生态承载力  为人均生物

生产面积; 为均衡因子; 为产量因子。

       2)区域生态承载力:

                     

 

式中: 为区域总人口的生态承载力 N为人口

数。
