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。结果两河村、下屯村、白草洼村、荞麦峪村在采暖期和非采暖期按监测指标总项次合格率分别为91.8%、90.0%、84.5%、92.7%和98.2%、98.2%、99.1%、93.6%;二氧化碳、甲醛、可吸入颗粒物、菌落总数5项指标各有不同程度超标;采暖期和非采暖期4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、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 research the indoor air quality and influence of different fuel on indoor air quality in new countryside. [Methods]The air quality in room was tested by the standard methods. [Results]The qualified rate of total indexes in Lianghe village,Xiatun village,Baicaowa village and Qiaomaiyu village during heating period and non-heating period was 91.8%,90.0%,84.5%,92.7% and 98.2%,98.2%,99.1%,93.6%,respectively.The level of carbon dioxide,formaldehyde,inhalable particulate matter and total bacteria exceeded the standard at different degrees.There was significant difference in qualified rate of total indexes of four villages between heating period and non-heating period（χ2=20.43,P0.01）.The air quality of carbon dioxide,total volatile organic compounds and total bacteria during non-heating period was better than that during heating period. [Conclusion]There exists slight indoor air pollution in new countryside.The mixed fuel which is the main energy source has great influence on indoor air quality.The indoor air quality in non-heating period is better than that in heating period.
