对郑州市１９８９～１９９１年的生活垃圾产量、成分，居民区苍蝇密度和肠道传染病发生情况等进行了调查，结果：郑州市居民人均日产生活垃圾１．２９ｋｇ，垃圾中有机物含量为２５．４２％；城市中垃圾清运较好的居民区苍蝇密度（９５只／笼·ｄ）和６～１０月肠道传染病发生率（３．１０％）均明显低于垃圾清运较差区的苍蝇密度（３４８只／笼·ｄ）和肠道传染病发生率（５．０３％）；市郊农村距垃圾场较远居民区的苍蝇密度（１９２５只／笼·ｄ）和６～１０月份肠道传染病发生率（６．１１％）也明显低于距垃圾场较近区的苍蝇密度（３４２９只／笼·ｄ）和肠道传染病发生率（８．４４％）。同时，６～１０月份肠道传染病发生率少年儿童（７．７９％）明显高于成年人（４．８２％），农村（６．１１％）明显高于城市（４．１１％）．提示控制肠道传染病的发生和流行，应做好城市生活垃圾的处理及卫生宣教工作。
The production, composition, flies density and the incidence of intestinal infectious diseases in municipal solid waste from 1989 to 1991 in Zhengzhou City were investigated. Results: The per capita average daily living garbage in Zhengzhou was 1.29kg, and the organic content in the garbage was 25. 42%. The density of flies (95 / cage d) and the incidence of intestinal infectious diseases from June to October (3.10%) in urban areas with better trash removal were significantly lower than those in areas with poor trash removal Flies density (348 birds / cage · d) and incidence of intestinal infectious diseases (5.03%); flies density (1925 birds / cage · d) in rural areas far away from the landfill and 6-10 months The incidence of intestinal infectious diseases (6.11%) was also significantly lower than the density of flies (3429 birds / cage · d) and the incidence of intestinal infectious diseases (8.44%) in the immediate vicinity of the landfill. In the meantime, the incidence of intestinal infectious diseases from June to October was significantly higher in juvenile children (7.79%) than in adults (4.82%) and in rural areas (6.11%) significantly higher than that in urban areas (4.11%). Prompt control of the occurrence and prevalence of intestinal infectious diseases, municipal solid waste should be done and health education mission.
