Asymptotic behavior of solutions in nonautonomous prey - predator system with beddington - type functional response
型功能性反應的非自治捕食系統的漸近性質 -
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
本論文基於當前生物學模型，特別是恆化器模型的研究現狀，深入系統的研究了時滯和擴散方程描述的幾類恆化器系統的漸近性態，本文的主要內容包括以下幾個方面：一、研究了具有beddington - deangelies功能性反應函數的時滯恆化器模型，利用無窮維連續動力系統的一致持續生存的理論給出了兩競爭種群一致持續生存的充分條件，利用單調動力學系統得到了系統的全局漸近穩定性。 -
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
當兩種獵物共存時，在不同總獵物密度下，測定了捕食者對各獵物的喜好性和轉換行為，分析了兩種獵物共存時，小黑瓢蟲雌成蟲對各獵物的功能反應形式，結果表明:當兩種獵物共存時，小黑瓢蟲雌成蟲對煙粉虱卵在低密度下不表現喜好性，而在中等密度和高密度下表現正喜好性，對紅蜘蛛卵在各密度下均不表現喜好性;對煙粉虱卵的轉換效應會由於總獵物密度的不同而呈現不同的效應，而對紅蜘蛛卵則在各總獵物密度下均呈現負轉換效應。
