摘 要：隨著社會經濟化和城市化進程的不斷加快，城市交通問題日益突出，城市機動車保有量急劇增加，產生諸如道路擁堵、大氣環境污染等一系列交通問題。本文首先利用多元回歸模型測算應用機動車保有量的因素，然后利用GM（1，1）模型預測影響沈陽機動車保有量未來5年的數值，并通過逐步回歸分析預測沈陽市2016-2020年的機動車保有量。
關鍵詞：機動車保有量 交通環境承載力 交通環境污染承載力

Abstract：With the continuous acceleration of social economization and urbanization， urban traffic problems have become increasingly prominent， and the number of urban motor vehicles has increased sharply， resulting in a series of traffic problems such as road congestion and atmospheric pollution. This paper first uses the multiple regression model to measure the factors that affect the number of motor vehicles in Shenyang， and then uses the GM（1，1）model to predict the value of the number of vehicles in Shenyang in the next 5 years， and predicts the 2016-2020 motor vehicle ownership of Shenyang through stepwise regression analysis.
Key words：vehicle ownership， traffic environmental carrying capacity， traffic environmental pollution carrying capacity
