摘　　要：目的研究单县水系分布与媒介按蚊密度及疟疾发病之间的关系。方法应用地理信息系统(GIS)和Google Earth 7.1软件对单县蚊媒孳生的主要水系以及2007—2011年疟疾当地感染新发病例进行分析。结合疟疾发病空间分布,于2012年,在单县黄冈镇与时楼镇设立蚊媒监测点,采用人饵帐诱捕蚊法及帐扣法观察蚊媒种群密度及季节消长情况。结果 2007—2011年疟疾病例主要分布于单县南部区域,病例分布与主要水系分布呈现出相对一致的趋势。单县黄冈镇与时楼镇共捕获成蚊2 407只,经鉴定为5属11种,黄冈镇捕获的成蚊种类和数量均明显多于时楼镇,其中中华按蚊的捕获数,黄冈镇为204只,时楼镇为29只,是时楼镇的7倍有余。中华按蚊的季节消长密度高峰为7—8月份,与疟疾发病高峰基本一致。结论单县水系分布与媒介按蚊及疟疾发病关系密切。单县水系分布影响中华按蚊的密度与分布,进而影响疟疾发病。Objective To investigate the relationship between the distribution of river systems, Anophe]ine population density and malaria incidence in Shanxian county of Shandong province. Methods The integral database of the major river systems for vector mosquitoes potential breeding habitats and all new autoehthonous malaria cases in 2007-2011 in Shanxian county of Shandong province were searched via GIS data collector and Google Earth 7.1 software and analized. Combining with the spatial distribution of malaria, Huanggang town and Shilou town in Shanxian county were selected as mosquito monitoring sites and overnight capture of mosquitoes with man-bait net trap and catching with a net in wild habitat were used to survey the population density and seasonal fluctuation in each monitoring site in 2012. Results Malaria cases from 2007 to 2011 were mainly distributed in southern area of the county, consistent to the distribution of river systems comparatively. Totally 2 407 mosquitoes were collected from the two monitoring sites. Eleven mosquito species belonged to 5 genera. The captured numbers and species of mosquito populations in Huanggang town were much higher than those in Shilou town, the number of Anopbeline sinensis in Huanggang Town was 204 seven times more than that in Shilou town （29）. The density peak of seasonal fluctuation of Anopheline sinensis was from July to August, eonsitent with the peak season of malaria incidence. Conclusion The prevalence of malaria in Shanxian county of Shandong province was obviously associated with the distribution of river systems, which influenced the Anopheline sinensis density and distribution.
