摘　　要：随着城乡一体化的快速发展,机动车数量的不断增加,城乡道路上机动车污染物排放量逐年增加,严重危害了道路两旁的城乡居民生活和健康。以最优化为前提,提出以污染物排量最小为目标函数,以路面状况、道路最高限速值、单车道交通流量及道路基本通行能力为约束条件来建立模型,得出城乡道路上机动车污染物排放量的有效计算方法。最后以合肥市出城口到肥东县一条干道-合店路为实例加以论证得出可行方法的结论。With the rapid development of urban-rural integration, the increasing number of motor vehicles, urban and rural road motor vehicle emissions to increase year after year, seriously endangering the life of the road on both sides of the urban and rural residents and health. Paper to optimize the premise of think- ing put forward in order to minimize emission of pollutants as the objective function to road conditions, the maximum road speed limit, the basic traffic flow and road capacity constraints to create models for the pro- posed rural road mobile vehicle emissions and effective method. Finally, the road exported from Feidong to Hefei, a trunk road - He Dian Road to practical examples,then, make a conclusion.
