dc.description.abstract本計畫將研究兩個相互競爭的物種之Lotka-Volterra反應擴散平流模型,在改變食物資源分佈下,觀察其物種數量演變的情形。將在二維有界的定義域下,給予週期的異質性環境,進行數值模擬與分析。本計畫將分為三個部分執行:(1)計算方法的建立-在一維定義域下,設定週期的異質性環境,找出有效率且準確的的離散方法來求得競爭模型的解;(2)時間相關的主題研究-針對二維定義域問題,在不同的週期異質性環境設定與參數下進行模擬,期望找尋出不同的物種競爭演變結果;(3)與時間無關的主題研究-剖析分歧現象是否存在於此模型上,進而刻畫出分歧類型,以及進行二維問題上物種競爭結果的穩定性分析。zh_TW
dc.description.abstractIn this project, to study evolution of conditional dispersal, a Lotka-Volterra reaction-diffusion-advection model for two competing species in a periodic heterogeneous environment is proposed and investigated. The two species are assumed to be identical except for their dispersal strategies: both species disperse by random diffusion and advection along environmental gradients, but with slightly different random dispersal or advection rates. We hope to develop a high efficient numerical algorithm with suitable discretization methods to deal with this reaction-diffusion-advection model for solving periodic solutions. Moreover, we would like to examine the stability of these solutions and bifurcation phenomena.en_US
