Firstly, the basic concepts and classical models of Lotka-Volterra system were introduced. Then the concepts of delay and K-monotonicity were introduced, and a three-dimensional delayed K-monotone Lotka-Volterra system was constructed and its equilibrium points and stability were analyzed. Then, by analyzing the roots of the characteristic equation and the Routh-Hurwitz criterion, the stability conditions of the equilibrium points were obtained, and the global asymptotic stability of the system was proved. Then, using the traveling wave theory, by constructing a suitable London equation and a system of differential equations, the traveling wave solution of the system was obtained, and its amplitude and propagation speed were analyzed. Finally, the correctness of the theoretical results was verified by numerical simulation.Keywords: Lotka-Volterra system, delay, K-monotonicity, stability, traveling wave solution.
