摘要
城市交通是城市生态环境的重要组成部分。它承担着该环境物质、能量、信息的转运传输功能 ,维系着城市生产与消费的平稳运行。然而 ,城市交通的发展在促进并改善城市社会环境与经济环境的同时 ,也给城市生态环境和自然环境带来不利影响。城市机动车和交通量的迅猛增加占用并消耗了大量的自然资源 ,比如土地和能源。同时 ,也对城市区域的大气环境、声环境、城市气候及温室气体产生明显的影响。为避免城市发展引起的生态环境日益恶化的趋势 ,研究设计科学合理的城市绿色交通网已成为当今城市可持续发展、改善城市生态环境的基础性工作之一。研究分析证明 ,城市轨道交通系统将明显改善城市交通拥堵、大大缓解对城市生态环境的影响。因此 ,随着人们环保意识的提高 ,城市轨道交通以其高效率、低消耗、低污染以及舒适、安全、快捷的特性逐渐成为现代化大都市的公交骨干系统。城市轨道交通的发展将为生态环境的改善、城市的可持续发展和建设 2
Urban transit system is an important component of the urban ecological environment It undertakes the transfer and transport function of material, energy and information in this environment And it also maintains the smooth running of city production and consumption However, development of urban traffic promotes and improves social and economical environment, but causes unfavorable effect on the urban ecological and natural environment Increased number of vehicles and traffic volume will made consume large quantities of natural resources such as land and energy.At the same time,there will cause obvious effect on atmospheric and sonic environment、climate and greenhouse gases in urban areas In order to avoid the deterioration trend of the ecological environment caused by urban development, it has been one of our basic duties to study and design the scientific and rational urban green transit system. Thus it will make the city develop econtinuously and improve the ecological environment of the city Urban railway transit system will obviously improve urban heavy traffic and ease the impact on the ecological environment People have realized the importance of the environmental protection.Urban railway transit system has gradually been a major urban mass transit system of a modernized city, due to its high efficiency, low consumption,small pollution as well as its comfort, safety and rapidity Development of urban railway transit system will make positive contributions to improvement of the ecological environment, the continuous urban development and the construction of the 21 century ecotype city
