摘要
山东省公路建设近几年得到了迅速发展,公路交通在促进经济发展的同时也给路域环境带来较为严重的污染。采用因子分析法,对山东省境内3条主要国道和5条高速公路的路域环境进行了综合评价。研究结果表明:同三和日东高速公路由于通车时间短,车流量也较少,车辆带来的空气和噪声污染并不严重,因而环境质量相对较好;而营运时间较长的济青、京沪和京福高速的环境质量相对差一些。虽然通车时间较长,但山东省国道的路域环境从总体上讲并不劣于高速公路。
Highway construction recently developed fast in Shandong province, which caused serious environmental pollution at the same time of improving the regional economy. The ecological environmental effects of three national highways and five expressways were evaluated by factor analysis in this paper. The results indicated that the environmental quality of Tongjiang-Sanya and Rizhao-Dongying expressways was relatively better than Ji＇ nan- Qingdao, Beijing- Shanghai and Beijing- Fuzhou expressways due to smaller traffic vehicle density. Compared to expressways, the environmental quality of national highways was not worse in spite of longer service time.
