【Abstract】 Based on the different time scales of population change, a singular system model for pest-natural enemy populations is established.Using the singular system theory, the geometric analysis of the model is carried out.Combining with catastrophe theory, the ecological mechanism of the outbreak of pest populations is revealed.The paper may provide a new idea for the establishment of pest populations management.更多还原
