The paper reports the results of investigation on quality of drinking water and water resources protection in rural areas of Hunan province, After water supply project, the sensory properties of drinking water improved significantly,the percentage of samples up to the standard on bacteria increased greatly. The percentage of overall indicators up to the standard also increased form 2.9%to 33.8%(X2=24. 91,P<0.01).The water quality index(WQI) was 6. 65 in places where there was water supply project while the WQI was 34. 84 in places where there was still no water supply project. The condition of water resources improved obviously(X2=ll. 9l,P<0.01).The results of the investigation can be interpreted as that the quality of drinking water and hygienic conditions of water resources improved after water supply project.

本文报道湖南农村改水水质及水源防护卫生的改善情况。改水后与未改水者比较,水质感官性状显著改良,细菌学指标合格率大幅度上升,各项指标都达标的水样数由2.9%提高到33.8%(X ̄2=24.91,P<0.01);水质综合指数改水后为6.65,而未改水者达34.84;水源防护卫生状况明显好转(X ̄2=11.91,p<0.01)。未改水对照点的条件与调查点改水前一致,故调查结果可视为改水前、后水质和水源卫生的变化。

为了对农村改水效益进行综合评价,我们按照国家水质分析的标准方法计算改水后水质中的细菌总数和大肠菌群下降50%,水质综合指数为改水前的19%;用环境流行病学的调查方法,在11602名人群中与饮水有关的甲型肝炎、伤寒、痢疾和肠炎每年的发病率比改水前分别减少2.20‰、0.39‰、2.70‰和14.30‰;用人力资本法计算得出减少上述疾病的经济损失为37238元/年,节省取水劳动力时间获取的经济效益为198644元/年;改水后增加家庭经济收入164188元/年。由此得出农村改水效益综合评价的指标为水质综合指数,肠道传染病的发病率,健康损害的经济损失、节省取水劳动力时间及家庭的经济收入。

t this paper,author was based on the surveillance to the quality of drinking water sources in the Lujiang countryside area,by means of the index of the hygiene quality of the water sources,calculated and evaluated the respective and combination index of the thirtythree kinds of the quality of the drinking water sources in the different geographical distribution areas.The results showed that the toxicology parameters of the drinking water sources were relatively safe in the different geographical areas.The maximum of the respective index were total number of bacteria and coliformgrop.The combination assessment indicated:(1)The grade five water sources account for 1515%,(2)The grade four water sources account for 7575%,(3)The grade three water sources account for 91%.In short of the parameter of total number of bacteria,the grade four,three,two water sources account for 303%,8787%,91% respectively.It showed the total number of bacteria was main affacting factor of the water sources quality with the different drinking water sources classifing in the countryside.Anthor suggested that the improved drinking water should come from the purified grade 2-4 water sources that reached to the grade 1 water sources paramegers.The combination index of the hygiene quality of the water sources were avavilable and pratical to the judging the grades of the quality of water on the survey of the drinking sources in the countryside.It makes a hygieneical profundity on the instruction of the improving quality of water sources in the countryside areas.

应用水质卫生指数对农村不同地理类型的33个生活饮用水源质量进行了综合评价。水质综合指数(KI)结果显示:五级水占15.15%,四级水占75.75%,三级水占9.1%。分指数最大值(Kimax)以细菌总数和大肠菌群最高。在去除细菌总数单项参数后,四级水占3.03%,三级水占87.87%,二级水占9.1%,表明了在农村不同饮水条件下,细菌总数对水质分级影响较大。改良农村饮用水选择二~四级的水源为宜,在经过净化处理后,方可达到一级清洁卫生水的期望值。
