[Abstract]:The predator-prey system in a copositional group is a complex system containing predation and competition. It is manifested in the fact that one predatory species consumes another and competes with the same prey and plays an important role in the formation of biota. Biochemometrics, which is usually expressed as a method to explain the ecological dynamics behavior by discussing the equilibrium between many chemical elements in the ecosystem, has been widely used in the study of biodynamic systems. The method of protecting ecosystem stability and biodiversity mainly adopts this important theoretical basis. In this paper, biochemometrics is used to study the predator-prey system in copositional groups. The coexistence of the co-predator-prey system with biochemometrics is discussed in detail. Based on two elements, phosphorus and carbon, a predator-prey system model with biostoichiometry was established. Through the theoretical analysis of the ecological matrix of the system and a large number of numerical simulations, it is proved that under certain conditions, the predator-prey system with biostoichiometry can coexist. In particular, it is shown that the relationship between the P / C ratio S1 and the P / C ratio S2 in the colocational predator plays a key role in the coexistence of the predator system in the cosite group.
