热带地区萨瓦那草原-森林的滞后作用类型

 

(1)  具有它们各自对森林成长所需最小干季降水量的单元的频率:

 

 

 

式中,是一个单元中森林秧苗成长所需的最小干季降水量;是标准差;是本地区一个单元中森林生长的平均最小干季降水量。

 

(2)  一个地区相对的森林覆盖度(A):

 

 

 

式中是平均干季降水量。

 

(3)  一个地区的总干季降水量,包括植物的贡献,表示为:

 

 

 

式中,分别是总的和输入的干季降水量;分别表示森林和萨瓦那草原蒸发蒸腾作用贡献的干季降水量。

 

(4)  森林和萨瓦那草原产生的干季降水量的计算可表达为:

 

 

 

式中,是森林和萨瓦那草原每天的干季水分蒸发蒸腾损失总量;是干季的天数;是降落下来的蒸发蒸腾水蒸气的比例。

 

(5)  假设一个森林面积为的地区遭受全球的气候变化,给本地区带来的总降水量为

 

 

 

这将引起的森林面积的变化,即,可以概括为:
