摘要
生态系统通过会聚、超循环和耦合而重组联合,从而形成新的能网结构。能网中某些能量作为体现能转化成较高质量的能量形式,这一高质能具有反馈放大器的作用,帮助系统达到最大功率,所以系统耦合必然导致生态效益的放大。系统内高质能与低质能的配置有三种情况:1.在一系统内高质能与低质能匹配良好;2.高质能相对过剩;3.低质能相对过剩。只有后两种情况有必要进行系统耦合,并能使系统的生产效益放大。
While the systems reorganized and the coupling system was token place through the process ofcon vergence,hypercycle and coupling,the new energy web structure was formed.Some of the energy in theenergy Web can transform into embodied energy,a kind of high quality energy.When the embOdied energyfeedback to the system,the amplification function may be happened and its power was enlarged to itsmaximum level.So the productivity of the coupling system may be increased tremendously.There are threecases of the energy cornposition between the embodied energy and the energy in common:1.The embediedenergy and the energy in common are just meet the necessary for the individual systems;2.The embediedenergy more than need;3.The energy in common more than need.Only the last two cases are necess,ary forthe systems coupling and are beneficial for the systems preductivity.
