| Abstract: | [中文摘要]：三带喙库蚊是云南地区主要乙脑媒介，而伪杂鳞库蚊也被怀疑在云南地区能起到传播乙脑的作用，它们的种群动态与特定地区的环境因素密切相关，也关系到当地乙脑的流行态势。本研究选择云南省南部边境地区盂腊县2个村：龙塘村和东方红村，在2村内设置16个诱蚊采样点，并应用地理信息系统对2村的三带喙库蚊和伪杂鳞库蚊种群与环境因素之间的关系进行分析。研究结果表明，灯点离水稻田最近空间水平距离（DTF）与灯点平方公里缓冲区间水稻田面积（KFA）、样点伪杂鳞库蚊种群优势度呈正相关关系；样点三带喙库蚊的优势度与灯点离河流最近空间水平距离（DTR）存在负相关关系；KFA与样点三带喙库蚊种群密度呈正相关关系。文章还在此基础上对西部开发中环境改变对这两种蚊虫乃至乙脑流行的可能影响进行了进一步探讨。
[英文摘要]： In southern Yunnan province, Culex tritaeniorhynchus is the major vector of Japanese B encephalitis （JBE） and Cx. pseudovishnui is also doubted as potential vector of JBE and variation of their populations correlate with environment factors and result in the tendency of the epidemic of the JBE. In this paper, GIS is adopted to study the relationship between the populations of the two mosquito species involving in JBE spreading and enviromnent factors. As the results showed, the DTF （the shortest distance of trap positions to rice fields） and KFA （the area of rice fields in a one-kilometer buffer of trap positions） are positively related to the dominance of Cx. pseudovishnui population, the DTR （the shortest distance of trap positions to the rivulet） is negatively related to the dominance of Cx. tritaeniorhynchus population, and the KFA is positively related to the population density of Cx. tritaeniorhynchus. The influence of the environment changes during Western Development Plan in China on the populations of JBE spreading mosquito vectors and epidemic of JBE are also discussed in this paper. |
