摘　　要：目的调查浙江省家鼠鼠疫疫源地的宿主与媒介种群在不同地区的动态结构及分布情况,为揭示鼠疫流行规律提供依据。方法运用灰色数学理论,对近年的各个地区、宿主动物、体蚤种群相关调查数据进行上限效果测度。结果对捕获的15种宿主动物(25 588只)及8种体蚤(1944匹)进行种群质量测度,其结果均有差别,即各个地区的宿主动物都有相应的优势种群,每个优势种群有相应的媒介种群;如果每个优势种群处于适当优势的情况下,则需要采取相应的措施进行警示性预防和调查。结论啮齿动物种群数量和蚤种类可以形成相应的计算数学矩阵,测度结果表明:如果宿主和媒介蚤种群数量处于相应优势状态,其测度数值的结果也愈大,说明该地区可能存在鼠疫的概率亦越大。Objective To investigate the dynamic structure and distribution of plague hosts and vector communities in various regions of Zhejiang province to understand the epidemiological characteristics of plague.Methods The gray mathematical theory was adopted to measure the maximum effect indices based on relevant data of different regions,hosts,and flea populations.Results Fifteen types of animal host（25 588） as well as eight types of body flea（1944） were subject to quality measurement,resulting in differences between each pair of groups,indicating a dominant species among host animals of each region and a vector population in each dominant community.Given adequate privilege of each dominant group,early warning,prevention and investigation shall be implemented.Conclusion A typical mathematical matrix can be formed based on the number of rodents and species of fleas.The quality measurement indicated that the larger vector and flea numbers resulted in high measurement results,suggestive of high risk of plague in the region.
