【摘要】 害虫灾害是高度复杂的大系统 ,表现出不均匀性、差异性、多样性、突发性、随机性、可预测性和周期性等复杂性特征 ,使得经典的理论和方法已不适用于害虫灾害的研究。依据复杂性科学和分形、神经网络、混沌及小波等非线性科学的发展及其近期在害虫灾害中的部分研究成果 ,该文从复杂大系统出发 ,构建了害虫灾害研究的复杂性理论框架 ,为深入研究害虫灾害的成因、机制与预测提供理论依据。更多还原

【Abstract】 Insect pest disaster systems are very complicated, exhibiting complex properties of irregularity, difference, diversity, sudden change, stochasticity, predictability and periodicity. These result in some classical theory and methods being unfit for research in this field. Based on the nonlinear development of complexity science, neural network theory, chaos theory and wavelet analysis, and the partial research results on insect pests; a framework for the application of complexity theory in insect pest disaster research is developed based on the concept of a greatly complicated system. This offers new theoretical support to further study of the cause, mechanism and prediction of insect pest disasters.更多还原
