【 摘 要 】

Under different ecological conditions, the results of animal evolution are different. As global warming and the environment deteriorates, the rate of species extinction is accelerating. Therefore, in this paper, the game between animal populations and ecology is studied, which provides a basis for more scientific protection of animals and environment. First, the animal's environmental needs are studied: By establishing the relationship between the heat gained by the animal and the required land area, there comes a fact that the more energy the animal consumes, the more land it needs. The land area is related to environmental factors such as temperature and precipitation. Therefore, given the natural conditions of a certain place, the land area can be obtained through the regression equation. Secondly, considering the long-term development, based on the ecological game model, the differential dynamic system is established. In different food supply situations, three game results of population and ecology are obtained: continuous growth, continuous reduction, and cyclical fluctuations.
