| 摘 要： | 以时空综合观分析了禾谷缢管蚜的种群动态，用模糊聚类分析方法将禾谷缢管蚜的数量发生动态分为 4 个状态，即凋落状态、初盛状态、盛发状态和衰减状态，认为应在初盛期进行化学防治。空间分布格局分析表明种群具有周期性聚集和扩散的规律。

| Abstract: | The population dynamics of Rhopalosiphum padi (L.) was analysed with an integrated view-point of time and space. Its occurring dynamics in number was divided into 5 states based on the results of fuzzy duster analysis. Chemical control of the pest was considered advisable at its initial occurring period. Analysis of its spatial distribution pattern showed that aggregation and dispersion occurred periodically in its population. |
