摘　　要：目的了解环境因素变化对疟疾流行和防治的影响。方法调查农村历年水稻耕作方式 ,历年农药使用情况 ,农村人居环境以及经济变化情况等。对比分析这些变化对媒介按蚊孳生繁殖和疟疾流行的影响。结果水稻推行湿润灌溉和农药使用量逐年加大 ,人房和牛房的媒介按蚊密度分别下降 71 .43 %和 86.73 % ,农村人居环境改善 ,人蚊接触减少 ,疟疾病例减少 ,流行强度减弱 ,流行季节高峰削弱 ,流行面逐渐缩小。结论水稻耕作方式的变化和农药的使用 ,有利于控制媒介按蚊孳生繁殖 ;Objective To make a clear understanding on change of environmental factors to malaria endemicity and control effectiveness. Method Rice plough model, insecticide supply, living condition, income changes, health education in farmers,and malaria control survey were carried out over the years and the influence to malaria endemicity and vector breeding were analysed. Results Wetting irrigation in rice fields, increase of insecticide supply and improvement of living conditions year by year, the anopheline density in human room and cowshed decreased by 71.43% and 86.65% respectively. Besides, mosquito man biting rate decreased, malaria incidence dropped, malaria endemicity weakened, epidemiological seasonal peak lowered and endemic range reduced. Conclusion Wetting irrigation method in rice fields and application of insecticide would be good at malaria vector control, and in addition to improvement of living conditions could roll back malaria.
