摘要
运用最优分割法(Fisher算法),对剑川鼠疫自然疫源地蚤类群落季节动态进行了研究,分为5个时段,根据结构与功能统一的原理.指出该疫源地的最佳灭蚤时间是2月末3月初。同时指出。如果防制时期选择不当.反而会使有害蚤的功能显现出来。
According to the unified principle of biological structure and function, it have been split into 5 intervals that the seasonal dynamics of the flea community of Jianchan plague natural focus and suggested that between the end of February and early of March is the optimum control time. Then, it also suggested that the function of fleas of harmful to human would come out if the control time was not selected correctly.
