以杨树—杨树烂皮病 (ValsasordidaNits )生态系统为研究对象 ,在杨树生长模型和杨树烂皮病流行模型的基础上 ,建立了杨树烂皮病危害的损失量模型和多维动态经济阈值模型。模拟了杨树—杨树烂皮病的系统动态 ,并根据杨树烂皮病常用的管理措施的防治效果 ,结合经济核算确定不同条件组合下的经济阈值 ,建立了杨树烂皮病的优化管理决策系统
Taking poplar-poplar badlands disease (Valsasordida neits) as the research object, based on poplar growth model and epidemic model of poplar rot disease, the loss model of poplar rot disease and the multidimensional dynamics Economic threshold model. The system dynamic of poplar-poplar rot disease was simulated. According to the control effect of commonly used management measures of poplar rot disease, the economic threshold of different conditions combination was determined by economic calculation, and the optimization of poplar rot disease was established Management decision system
