生物量和光能利用效率的测定模型

 

1.生物量和生产量的测定

 

(1)  生物量模型:

 

 

式中,为植物相应部分的干生物量;分别为胸径和树高。

 

(2)  净生产量模型:

 

 

式中,为样地面积;分别为第21次调查时的生物量;为凋落物量(每月收集一次);为死木(每年调查一次);为动物、昆虫啃食量(每季调查一次)。

 

2.植物光合、呼吸速率的测定

 

(1)  净光合速率模型:

 

 

 

 

(2)  呼吸速率模型:

 

 

 

 

式中,为叶室或呼吸装置内外气体的含量之差;为叶室或呼吸装置内外气体流量;为叶面积;为呼吸器官的干重;为叶室或呼吸装置内的温度; 为大气压。

 

3.群落植物生产力和光能利用效率的计算

 

(1)  净生产力模型:

 

 

 

 

 

 

 

 

 

(2)  光能利用效率模型:

 

 

 

 

 

 

式中,为叶子的夜呼吸量;为其他各部分器官的呼吸量;为光合作用或呼吸时间;为呼吸器官干重;为叶面积指数;为各层植物对吸收能量的利用率;为群落对能量的利用效率;为单位土地面积吸收的能量。
