鸡舍内粉尘浓度过高．会危害饲养员的健康和家禽的生产力，还会对周围环境造成污染。了解鸡舍内粉尘浓度空间变化情况，有助于进一步分析粉尘释放和变化规律，为开发更有效的除尘方法，试验测定了规模化养鸡场一年四季鸡舍门口和鸡舍中央的粉尘含量。结果表明，鸡舍中央位点全尘春季与冬季、秋季与冬季差异显著（P〈0．05），夏季与冬季差异极显著（P〈0．01）；呼吸性粉尘PM10夏季与秋季差异显著（P〈0．05），春季与冬季、秋季与冬季差异极显著（P〈0．01）；四季呼吸性粉尘PM10鸡舍中央位点与鸡舍门口差异不显著（P〉0．05）；全尘TSP鸡舍中央位点与鸡舍门口差异也不显著（P〉0．05）。

Excessive dust concentration in chicken house is hazardous for workers' health and poultry productivity, and also is harmful to the environment. To understand dust spatial distribution is helpful to analyze the emission and transmission of dust, and is helpful to develop more effective control methods for dust. The content of dust in the door and central of chicken house in scale chicken farm throughout the year was detected. Results show that the full dust of central bit point had significant difference between spring and winter as well as between autumn and winter (P〈0.05), and had very significant difference between summer and winter (P~0.01). The respirable dust PM10 had significant difference between summer and autumn (P〈O.05), and had very significant difference between spring and winter as well as between autumn and winter (P〈0.01). The seasons respirable dust PM10 in central had no significant difference with that in door(P 〉0.05 ). The full dust TSP in central also had no significant difference with that in door(P 〉0.05).
