摘　　要：在四能带模型的基础上 ,建立了光系统 II各功能单元间的能量传递动力学模型 ,分析了不同光照情况下的能量传递差异情况 .在适当光照下 ,能量以单向优化方式传递到反应中心 ,能耗很小 ;在强光照射下 ,发生逆向能量传递 ;在超强光照射下 ,会引起光合器官损伤 .The dynamic model of energy transfer between each function unit of photosystem Ⅱ was made by improving a four band model.The difference of energy transfer with different light intensity was analyzed.With suitable light intensity,energy was transferred to reaction center with a single direction optimized way and the dissipation of energy was faint.With strong light,the reversed energy transfer occurred and photosynthetic organism was damaged with ultra strong light.
