摘  要：
为筛选鸡舍综合环境评价中的主要影响因子并确定其权重值,使鸡舍综合环境评价指标体系的构建更加科学合理。采用灰色关联分析法对易县某鸡舍的13项环境指标与舍内肉鸡生长指标进行关联分析,并使用灰色关联度改进层次分析法中判断矩阵的构建方法。结果表明:对该鸡舍综合环境影响较大的前5个影响因子为舍外风速、湿度、温度、舍外温度、NH3浓度,其对应的权重值分别为0.255 2、0.238 2、0.123 3、0.109 6、0.091 9。虽然试验鸡舍处于秋季封闭管理状态,但因通风系统的存在,外界环境依然对舍内环境有较大影响,因此在构建鸡舍综合环境评价指标体系时也应考虑将外部环境指标纳入。研究结果为筛选鸡舍综合环境评价主要影响因子以及确定权重提供了一种相对科学严谨的方法,可为后续鸡舍综合环境评价模型的构建以及舍内环境调控提供参考。

摘  要：
In order to screen the main influencing factors and determine the weight value of comprehensive environmental assessment for chicken coop and build a more scientific and reasonable index system of comprehensive environmental assessment for chicken coop. In this paper, 13 environmental indexes of a chicken house in Yi County were analyzed by using grey correlation analysis method and the construction method of judgment matrix was improved by using grey correlation degree. The results showed that the top five influencing factors were wind speed, humidity, temperature, temperature and NH3 concentration, and their corresponding weight values were 0.255 2, 0.238 2, 0.123 3, 0.109 6 and 0.091 9, respectively. Although the experimental chicken coop was in the closed management state in autumn, the external environment still had a great influence on the internal environment due to the existence of ventilation system. Therefore, the external environment index should be considered in the construction of the comprehensive environmental evaluation index system of the chicken coop. This paper provided a relatively scientific and rigorous method for screening the main influencing factors and determining the weight of the comprehensive environmental assessment of the chicken coop, which could provide reference for the subsequent construction of the comprehensive environmental assessment model of the chicken coop and the regulation of the environment in the chicken house.
