森林火災を模擬した二次元インパクトモデルの定性的性質 Qualitative Analysis in a Second-Order Impact Model for Forest Fires
Natural forest fires are the problems that influence ecosystems, and they have been researched from of old. For solving this problem, a prediction model for forest fires was proposed. The model imitates fires that are seen in mediterranean forests, boreal forests and savannas. In recent years, it was simplified a second-order impact model. Furthermore, the model of mediterranean forests have been analyzed. However, the others are insufficient yet, and the qualitative property of forest fires has not been discussed enough. In this letter, we analyze the second-order impact model that is seen in boreal forests and savannas. Moreover, we consider what bifurcation phenomena essentially influences some periodic solutions.
