Ecological agriculture model is an agricultural ecosystem with optimized structure and function formed in agricultural production practice, which takes into account the economic, social and ecological benefits of agriculture. According to the organizational level of ecology, eco-agriculture model can be divided into three levels, namely, regional and landscape layout model, ecosystem cycle model and biodiversity utilization model. In an agricultural area and a landscape area, the most important thing is to balance the overall layout of agricultural production, life and ecological functions. In an agricultural ecosystem where energy and material flow are connected in series, the most important thing is to ensure the smooth flow of energy and material and the recycling of material.
