摘　　要：针对美国环保署最新开发的MOVES2014a模型中输入参数较多、输入流程繁琐、参数不易获得等特点,需要对参数的输入进行适当简化处理。本文分别考察了年份、温度、湿度、车龄、车速和车流量等6个参数对MOVES2014a模拟一氧化碳(CO)、氮氧化物(NOx)和总碳氢化合物(THC)等3种排放因子的影响。结果显示,与CO和THC排放因子呈正相关的有温度和车龄,呈负相关的有年份和车速;与NOx排放因子呈正相关的是车龄,呈负相关的有年份、温度和车速;湿度和车流量的变化对3种污染物排放因子几乎无影响。本研究结果对使用MOVES2014a进行本地化模拟机动车排放因子提供了参考。According to the characteristics of MOVES2014a model recently developed by EPA,such as a large number of input parameters,cumbersome input process and inaccessible parameters,etc.,it is necessary to simplify the input parameters for this model.Therefore,influences of six parameters such as year,temperature,humidity,vehicle age,vehicle speed and traffic flow on the emission indices of carbon monoxide(CO),nitrogen oxides(NOx)and total hydrocarbons(THC)were examined.The results show that the emission indices of CO and THC are positively correlated with temperature and vehicle age but negatively correlated with year and vehicle speed;the emission index of NOx is positively correlated with vehicle age but negative correlation with year,temperature and vehicle speed;and the parameters of humidity and traffic flow have little influence on the emission indices of these three kinds of pollutants.The results of this study provided a reference for using MOVES2014a to simulate local vehicle emission index.
