Impact of Chinese Expressway on the Ecological Environment

Abstract

Expressway has a deep, irreversible influence on the ecological environment. Through assessment and evaluation on several expressways in the territory of China, this paper shows that the main source of air pollution caused by expressway is motor vehicle exhaust and dominated by lead pollution; noise pollution caused by expressway is mainly traffic pollution along the road during operation. However, the noise pollution is seriously overweight; the construction and operation of expressway has an impact on water environment, water and soil conservation and living environment for animals and plants. At the same time, the closure of expressway operation has impeditive functions to residents living along the road.
