摘要
长尾黄鼠是鼠疫自然疫源地的主要储存宿主之一,其体外寄生蚤是传播鼠疫的主要媒介。考察体外寄生蚤的种群动态,无论在蚤类理论生态学方面,还是在鼠疫流行病的理论研究及周测方面都有重要意义。 种群动态是复杂的问题,涉及数量动态与空间动态两方面的内容,可以从不同侧面、不同角度,使用不同方法去研究。迄今。
The population dynamics of the parasitic fleas on Citellus undulatus were regarded as a system using fuzzy set with synthetical considerations of the information on quantitative and spatial dynamics, and the whole system was divided into four subsystems as a result of the fuzzy cluster analysis. The population dynamics marked with these subsystems closely correlated to ecological action and corresponded to four ecological periods of its reservoir in time sequence.
