【摘要】:共位群內捕食系統(tǒng)是蘊含了捕食和競爭的復雜系統(tǒng),表現在一類捕食物種消耗另一類捕食物種并且為共同的食餌競爭,且在組成生物群落中的起到重要作用.生物化學計量法通常表現為通過討論生態(tài)系統(tǒng)中多種化學元素之間的均衡問題來解釋生態(tài)動力學行為的一種方法,已經被廣泛應用到生物動力系統(tǒng)的研究之中,保護生態(tài)系統(tǒng)穩(wěn)定性和生物多樣性的方法也是主要采用了這一重要的理論依據. 本文將應用生物化學計量法研究共位群內捕食系統(tǒng),詳細地討論了引入生物化學計量法后的共位群內捕食系統(tǒng)的共存問題.首先以磷和碳兩種元素為基礎,建立了帶有生物化學計量的共位群內捕食系統(tǒng)模型.通過對系統(tǒng)的生態(tài)矩陣的理論分析和大量的數值模擬驗證了在一定條件下,帶有生物化學計量的共位群內捕食系統(tǒng)是可以共存的.特別地,研究表明共位群捕食者體內的磷碳比s1和共位群食餌體內磷碳比s2的大小關系在共位群內捕食系統(tǒng)共存中發(fā)揮著關鍵作用.
[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.
