昆虫种群活动数量的变化不仅受当时气象等环境因素的影响,而且与种群自身数量的节律变化有关。种群在一定空间与时间内表现的数量,包括空间、数量对种群作用的当时和时间序列上的过去,内含复杂的多因素函数关系。国外曾有人用多元回归和时间序列等分析气象因素对吸血蠓和蚊虫活动的影响,建立预测方程。国内也有用马尔可夫链转移概率、随机序列与周期方程、多元逐步回归和生命表等分析农业害虫种群数量的变化,建立 The change of insect population activity is not only affected by the environmental factors such as meteorology at that time, but also with the change of rhythm of the population itself. The number of populations in a certain space and time, including the spatial and the number of the population at the time and the time series of the past, contains a complex multi-factor function. Some people abroad have used multiple regression and time series analysis of the impact of meteorological factors on the activities of vomiting and mosquitoes, the establishment of prediction equations. China also uses Markov chain transfer probability, random sequence and periodic equations, multiple stepwise regression and life table analysis of agricultural pest population changes, the establishment of
