目的了解济南地区农村改厕对蝇类种群密度的影响,评价农村改厕的卫生效果。方法卫生效果评价以蝇类种群密度为指标,采用捕蝇笼诱捕法。结果农村改厕申家庄、明理和七里堡3村,平均蝇密度为3.6只.笼-1.8 h-1;未改厕的西铺、清水坡和西张3个对照村,平均蝇密度为65.93只.笼-1.8 h-1,改厕农村蝇类种群密度与未改厕农村相比,平均下降了94.54%(t′=4.18,t′0.01=3.01,P<0.01)。结论农村改厕使农户用上了节水型高压水冲式卫生户厕,能够使蝇类种群密度大幅度下降,农民的生活环境质量得到明显改善和提高,卫生效果良好。
Objective To understand the impact of toilet flushing in rural areas on the population density of flies in Jinan and to evaluate the hygienic effect of toilet flushing in rural areas. Methods The health effects were evaluated by the flies population density as an indicator, using flycatcher trapping method. Results Rural toilets in Shenjiazhuang, Mingli and Qilibao 3 villages had an average flies density of 3.6 cages -1.8 h-1; three control villages, namely Xipu, Qingshuipo and Xizhang without toilets, had an average fly density of 65.93 cages -1.8 h-1. The density of toilet flies in rural areas was reduced by 94.54% on average (t ’= 4.18, t ’0.01 = 3.01, P <0.01). Conclusion Rural restroom makes farmers use water-saving high-pressure flushing toilet, which can greatly reduce the population density of flies and improve the quality of living environment of peasants. The hygiene effect is good.
