摘　　要：元江流域九十年代以来平均每年大约有 54万人次流动人口到海拔 80 0米以下的河谷地区进行热区开发 ,流动人口的年带虫发病率 ( API)、血片阳性率 ( SPR)、原虫率分别是当地居民的 50倍、2 .6倍、2 .2 6倍 ,该地区已成为向两岸山区及省内外输出疟疾的疫源地。山区、半山区下坝生产者和外来流动人员大多露宿垦殖地 ,无防蚊设备 ,吸引了媒介按蚊外栖性与外食性 ,使常规室内滞留喷洒措施难以奏效。大量无控制的流动人口为疟疾防治工作带来困难 ,也严重威胁流域各县灭疟成果的巩固。提示加强流动人口的管理和对各种防治措施的宣传 。Since 1990s, an average of about 540 thousand person times per year of transient population have come to river valley region, a torrid zone with sea level below 800 m, of Yuanjiang basin for development The annual parasite incidence (API), slide positivity rate (SPR) and parasite rate of transient population were 50 times, 2 6 times and 2 26 times as that of local residents respectively Therefore, the river valley region has become a focus in transmitting malaria to both side of mountainous areas and inside or outside the Yunnan Province Most of the local and transient population were used to sleeping in the open without mosquito net which caused the exophily and exophagy of the vector, and made the indoor residual spraying hard to be effective It has been suggested by the authors that to achieve and consolidate malaria control effect, the management of transient population as well as the malaria control measures should be carried through and practicable
