The Nonlinear Study Of A Ecological Model In Seasonal Rainfall

In this paper, we will recommend an ecological model with fully seasonal rainfall,and introduce the concepts and e?ects of the dimensionless disposal and bifurcationgraph.Through dimensionless disposal, we can get a more concise pattern which is bettersuits numerical simulation and numerical calculation. With the results of the numericalcalculation, we can draw bifurcation graph, and lay foundations for further study suchas seek tangent linear model, adjoint model, gradient and conditional nonlinear optimalperturbation which will have a certain guiding significance to the agricultural productionand desertification control.
