摘　　要：目的了解新农村室内空气质量和不同燃料能源对室内空气质量的影响。方法采用标准方法对居室内空气质量进行检测。结果 A村、B村、C村、D村在采暖期(非采暖期)按监测指标总项次合格率分别为92%、90%、84%、93%(98%、99%、99%、94%);二氧化碳、甲醛、可吸入颗粒物、菌落总数五项指标各有不同程度超标;采暖期和非采暖期四村合计总项次合格率比较差异有统计学意义(χ2=20.43,P<0.01);二氧化碳、可吸入颗粒物、总挥发性有机物、菌落总数非采暖期室内空气质量好于采暖期。结论新农村室内空气质量存在轻微的污染,混合燃料为主要能源对室内空气质量影响较大,非采暖期室内空气质量好于采暖期室内空气质量。Objective To investigate the indoor air quality in new rural areas,and to explore the effect of different fuel energies on indoor air quality.Method The indoor air quality was examined with the standard method.Results The total qualified rates of surveillance items in villages A,B,C,and D during the heating period and the non-heating period were 92%,90%,84%,and 93%（98%,99%,99%,and 94%）,respectively.The five indicators,including CO2,HCHO,PM10,TVOC,and total plate count,exceeded the standard in varying degrees.There were statistically significant differences in the total items qualified rates of the four villages during the heating period and the non-heating period（χ2=20.43,P0.01）.CO2,PM10,TVOC,and total plate count in indoor air of the non-heating period were better than those in indoor air of the heating period.Conclusions The indoor air of the new villages has a slight pollution.The mixed fuel energies affect the indoor air quality.The indoor air quality during the non-heating period is better than that during the heating period.
