棉田生态系统能流特征分析模型

 

(1)棉田初级生产者呼吸量𝑅模型:

式中,𝑊为棉株重量;∆𝑤/∆𝑡为单位时间内棉株重量的变化;𝑎,𝑏为棉株的呼吸常数;𝛼氧卡系数

(2)次级生产者呼吸量R模型:

式中,𝑛,𝑚分别为节肢动物的种类数和调查次数;𝑊𝑖,𝑘-1,𝑊𝑖,𝑘分别为第𝑖𝑘-1次和𝑘次调查时的生物量;𝑅𝑖为第𝑖种的呼吸代谢率;𝛼𝛽分别为氧卡系数和田间呼吸量修正值;𝑓(𝑇𝑘)为第𝑘次调查时温度系数的作用;𝐷𝑘为第𝑘-1次到第𝑘次调查时的时间间隔。

(3)土壤分解者呼吸量𝑅模型:

式中,𝑊0~10cm深度的土壤干重;𝑅𝑘-1𝑅𝑘分别为第𝑘-1次和第𝑘次测定时土壤呼吸强度;其他同上。
