森林系统模拟模型

 

(1)林地中树木的数量𝑄只能随时间而减少,没有再生,即:

(2)高度(𝐻)和直径(𝐷)的生长为正值或0时,可表达为:

(3)树叶数量𝐿,好根数量𝑅和果实数量𝐹按它们各自的增长率增加,按枯萎率减少,同时还随树木的死亡而减少,可表达为:

(4)同化储量𝐴增加:

(5)木材量𝑊

(6)木材中转变的氮总量𝑁w

式中,𝑞dead是树的消枯率;hgrow是高度增量;𝑑grow是直径增量;𝑙grow是实际叶片更新生长率;𝑙loss是树叶脱落率;𝑙dead是死亡树木的树叶数量损失率;𝑟grow是实际的根更新生长率;𝑟loss是好根损失率;𝑟dead是死亡树木的好根数量;𝑓grow是果实生长率;𝑓loss是果实损失率;𝑓dead是死亡树木的果实;𝑎prod是树冠每天的生产率;𝑎reloc是吸收重置的鼓舞;𝑎resp总维持的呼吸作用;𝑎dead是死亡树木中的吸收损失;𝑤incr是木材数量的增加率;𝑤loss是总死亡木材的损失率;𝑏是呼吸消耗与总木材量的比率;𝑣0是呼吸树木的氮容量;𝑣𝑖是死亡树木的氮容量;𝑣w是树木中氮的平均浓度。
