Research progress and trends in system coupling and discordance for grassland agroecosystems
草地农业生态系统中的系统耦合与系统相悖研究动态

The coupling of agro-ecosystems was initially put forward at the end of the 80s. In the middle of the 90s, Ren Ji-zhou and others systematically described the theory of system coupling which showed that system coupling is two or more potentially coupled systems, under artificial control of input and output of energy flow, material flow and information flow in larger systems, coupled to form new superior structure -function bodies. The general function of coupling between systems is to consummate the struct...
