资源消耗的生态价值系数评估模型

先定义破坏系数为人类活动消耗的第i个有用产品的量与废物侵蚀性组分K的㶲之比:

 

再定义破坏系数为消耗的自然资源的第S个组分的㶲与废物侵蚀性组分K的㶲之比:

 

式中,破坏系数取决于废物源的位置和侵蚀性组分的浓度。通常只需考虑废物侵蚀性组分K的化学㶲,但当物理㶲对环境也有破坏作用时(如废热引起  的热污染),则物理㶲也要被考虑进去。

自然资源的消耗(㶲消耗)可以用生态价值系数表示。下面方程表示在最后的生产步骤中,生产第j个过程的单位主产品(表示),k个自然资源的生态价值系数的平衡:

 

式中, 为生产单位主产品,在所考虑的过程中直接消耗的第S个自然资源的㶲;为生产单位第j个主产品,废物的第k个侵蚀组分的㶲;分别为在生产的最后过程中,第j个单位产品的第i个中间产品的副产品系数和消耗系数。

引入辅助系数:

 

或用矩阵形式:

 

 

式中,分别为系数, 的三角矩阵,则方程(3)就可以写成:

 

 

或用矩阵表示为:

 

式中,为量三角矩阵;为具有S个元素的单位矢量阵;为量的向量矢量;为单位阵;为系数的平方阵。

 

   从方程(10)可以得出:
