摘　　要：在一维Logistic模型的基础上,提出了一种新虫口模型,研究了该新虫口模型的的混沌特性,发现其具有更丰富的混沌动力学行为,包括周期并缩等新奇现象.并利用辅助参考反馈控制法对此新虫口模型进行了混沌控制,成功地将其控制到低、高周期的各种不同轨道,控制的速度快,稳定性好,且控制时灵活方便.In this paper, a new model of ＂the number of insect ＂is proposed based on one-dimensional Logistic model and chaos characteristic of the model is investigated. The result shows that there are abundant chaos dynamic properties, inclouding some novel evolution patterns such as the periodic coalescence, By means of control method with an auxiliary reference feedback, the model is successfully controlled into a variety of different orbits of high/low periods. The method has the following advantages in swiftness,stability, flexibility and convenience.

关 键 词：新虫口模型 混沌 辅助参考反馈 混沌控制
