- Asymptotic behavior of solutions in nonautonomous prey - predator system with beddington - type functional response
型功能性反应的非自治捕食系统的渐近性质 - In the light of the recent work in biological models , especially in the chemostat models , the dissertation provides a systematic study on the asymptotical behaviour of some chemostat models built by delay or diffusion differential equations . the main contents and results in this dissertation are as follows : i ) the global asymptotic behavior of the chemostat model with the beddington - deangelies functional responses and time delays is studied . the conditions for the uniform persistence of the competing populations are obtained via uniform persistence of infinite dimensional systems
本论文基于当前生物学模型，特别是恒化器模型的研究现状，深入系统的研究了时滞和扩散方程描述的几类恒化器系统的渐近性态，本文的主要内容包括以下几个方面：一、研究了具有beddington - deangelies功能性反应函数的时滞恒化器模型，利用无穷维连续动力系统的一致持续生存的理论给出了两竞争种群一致持续生存的充分条件，利用单调动力学系统得到了系统的全局渐近稳定性。 - The relationship among searching efficiency ( e ) , the prey density ( n ) and the adult ladybird density ( p ) was simulated as e = 0 . 3 1 10 / ( 0 . 7842 + 0 . 000404 n + 0 . 21 58 p ) by beddington ' s model e = at / [ 1 + athn + btw ( p - 1 ) ] , i . e . the searching efficiency declined when the adult ladybird and the prey densities increased . in the single predator - two preys system , the selective predation of the adult female beetle to both eggs of b . tabaci and t . nr . fijiensis was discussed when two preys coexisted
当两种猎物共存时，在不同总猎物密度下，测定了捕食者对各猎物的喜好性和转换行为，分析了两种猎物共存时，小黑瓢虫雌成虫对各猎物的功能反应形式，结果表明:当两种猎物共存时，小黑瓢虫雌成虫对烟粉虱卵在低密度下不表现喜好性，而在中等密度和高密度下表现正喜好性，对红蜘蛛卵在各密度下均不表现喜好性;对烟粉虱卵的转换效应会由于总猎物密度的不同而呈现不同的效应，而对红蜘蛛卵则在各总猎物密度下均呈现负转换效应。
