【摘要】：共位群内捕食系统是蕴含了捕食和竞争的复杂系统,表现在一类捕食物种消耗另一类捕食物种并且为共同的食饵竞争,且在组成生物群落中的起到重要作用.生物化学计量法通常表现为通过讨论生态系统中多种化学元素之间的均衡问题来解释生态动力学行为的一种方法,已经被广泛应用到生物动力系统的研究之中,保护生态系统稳定性和生物多样性的方法也是主要采用了这一重要的理论依据. 本文将应用生物化学计量法研究共位群内捕食系统,详细地讨论了引入生物化学计量法后的共位群内捕食系统的共存问题.首先以磷和碳两种元素为基础,建立了带有生物化学计量的共位群内捕食系统模型.通过对系统的生态矩阵的理论分析和大量的数值模拟验证了在一定条件下,带有生物化学计量的共位群内捕食系统是可以共存的.特别地,研究表明共位群捕食者体内的磷碳比s1和共位群食饵体内磷碳比s2的大小关系在共位群内捕食系统共存中发挥着关键作用.
[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.
