【摘要】 城市环境和交通密切相关,在城市环境和交通问题日益突出的今天,各国、各城市都在寻找解决的出路。作为河谷型城市的兰州,相对于国内同等规模的平原城市,这两个问题更为突出,解决起来更为迫切。本文就兰州市交通与环境的若干关系进行了研究,在对目前交通与环境关系研究进行总结的基础上,研究了下面四个问题: (1) 交通需求与土地利用的关系研究。通过对兰州市土地利用现状的分析,结合规划方向,进行了土地利用的比较分析。进而分析了在目前土地利用现状下交通需求的特点、预测了2010年的交通需求状况和机动车保有量情况,最后对兰州市土地利用规划和交通需求进行了评价并提出了建议措施。 (2) 交通的环境影响分析。兰州市区交通量构成中公共交通车辆占到40%,交通对环境的影响在很大程度上是公共交通造成的,其中大中型车辆的影响更加明显,所以选择定时定线公交系统进行分析。分析公交系统的环境影响、交通流的噪声影响、公交站点和干道的噪声影响以及大气环境影响。 (3) 交通政策的环境影响分析。作为交通发展方向和要求的交通政策对环境的影响从广义环境的角度进行了探讨。 (4) 基于可持续的交通模式分析。可持续的交通是21世纪兰州市发展要考虑的问题,结合兰州市的土地利用以及实际情况进行了分析,提出兰州市未来的交通模式。更多还原

【Abstract】 The urban environment is tightly related to the traffic. At present, problems between the urban environment and the traffic are becoming more and more serious, and much more countries and regions are seeking ways to solve the problem actively. As a river valley city, compared with the other moderate scale cities, this problem becomes more prominent and urgent in Lanzhou, Gansu province. This paper studies some relations between the traffic and the environment, and the results on the basic relations are summarized as follows:(1) The relation between land use and traffic demands is studied. According to the planning guides, it analyzes the present conditions of land use. Furthermore, it also analyzes the characteristics of traffic demands and forecasts the traffic demands and the amount of power-driven vehicles in 2010. At last, it assesses the planning of land use and traffic demands and some measures are proposed.(2) The traffic impact on the environment is analyzed. Public vehicle, especially the impact of the big and middle buses, is 40% in the total traffic capacity in Lanzhou, which is becoming the principal and important section. So the public transport of regular time and route is chosen and analyzed. It includes the environment impact of the transit, the environment noise impact of the vehicle flux, analysis of noise pollution of the traffic sites and mail roads, and the environment impact of atmosphere.(3) It analyzes the environment impact of the traffic policy. In an extensive sense, the traffic policies as an orientation and requirement, its influences on the environment are discussed.(4) Based on the analysis of the sustainable traffic patterns, we should take measures to make the transport development a sustainable style in the 21th century, associated with the land use and the actual conditions in Lanzhou.更多还原
