生态系统服务功能评价模型

 

(1) 陆地生态系统径流调节模型:

1)  陆地生态系统一年内的径流调节能力可用下式表示:

式中,分别代表雨季和旱季陆地生态系统的径流调节能力;μ是一个与雨季降雨强度有关的降雨等价值。

式中,C是一棵树所覆盖的单位面积截留的雨水量;L是指落叶层所包含的水量;G是地下水的保持量;R是地下水的排出速率。

2)  流域中每种类型的复合体对径流的调节能力由下式决定:

式中,是第i类复合体一年内对径流的调节量,是每类复合体的系数。

3)  所以复合体的多年平均径流调节量可由下式得到:

式中,是第i类复合体的面积。

(2) 水电产出与市场价值模型:

1)  长江的径流量与葛洲坝水电站产生的电力的关系可用下式来描述:

式中,H是葛洲坝水电站产生的电力;Q是长江的径流量。

2)  流域陆地生态系统调节径流产生的经济价值可用下式计算:

式中,Va是葛洲坝水电站产生的电力的价值;P是单位电价。

(3) 经济补偿模型:

该地块的土地所有者获得的经济补偿可用下式估算得到:

式中,分别表示单位面积上由第j类植被、第k类土壤、第l类的坡面所调节的径流量;为该地块面积;B是土地所有者从单位净流量产生的电力中所获得的收益。
