【摘要】 对舞毒蛾卵块的种群动态与温度、湿度等气象因子相关分析.找出了相关系数较大的因子。建立了相应的回归模型。回归检验得出利用2月下旬的温度来预测4月份的舞毒蛾卵块种群动态。效果较好。
【Abstract】 Through the relationship analysis between the egg block population and the meteorological factors such as temperature and relative humidity, the good correlation factors are found. and the relative regression models are established. By regression test. the best way to predict the Lymantria dispar L. egg block population in April is to use the temperature of the last ten days of February,
