摘要: 目的:研究蜚蠊种群与环境因子的相互关系,为制定防制对策和预测预报提供理论基础。方法:应用灰色关联分析。结果:降雨和温度是影响蜚蠊种群密度的重要因子,并利用富立叶调和函数建立种群动态的时间序列模型,模拟结果满意。结论:降雨量多、温度高的季节,亦是蜚蠊密度高峰期,此前是控制其危害的最佳时机。

Abstract: This paper employed grey relative analysis to study the relationships between environmental factors and population dynamics of cockroach adults.The importance of environmental factors were ranked:rainfall>temperature > humidity > sunshine.A mathematical model with Fourier Series were constructed to model the population dynamics, the fitting results were good enough.This can provide guidance to the forcast and contro of these insects.
