控制草原鼠患模型
The Model of Grassland Rodents Control
摘要
Abstract
Three methods were adopted to analyze economic benefit and deratization effect. Model 1: The logistics model was adopted to describe the variation function of mouse quantity with time in the condition of without use any deratization measures; Model 2: Adding a constraint function which varied with time, deratization quantity, effective deratization time and cost were obtained through MATLAB program; Model 3: The variation trend between enemy and mouse was observed through introducing Volterra predator-prey model, then short-term, long-term effects and capital investment were obtained; Model 4; On the basis of logistics model, introducing pasture retardation factor , the effective time and cost of deratization quantity were obtained through MATLAB.关键词
