【摘要】：城市绿地是城市惟一有生命的基础设施,是人、城市、自然和谐的基础,也是完善城市生存环境和维持自然生态平衡的关键要素。城市绿地建设的生态化是近几年城市绿地系统规划和城市规划的重要部分,它既是社会发展的基本要求,也是现代城市发展的趋势。近年来,由于城市建设的不断发展,人们对道路交通绿化的要求越来越高,不仅要求其安全、快捷、经济、方便、舒适,而且要求其能给人以精神上美的享受,同时对周围环境友好,能满足人们随时呼吸到新鲜空气和享受安静等作用的迫切需要。从对一座城市的生态影响上来看,如果沿城市道路两侧种植乔木、果树、灌木、矮林、牧草、花卉,营造小型园林,不但可以美化环境、净化空气、吸收噪音、改善行旅条件、有利于行车安全,而且可以稳定路基,遮荫路面,延长道路使用寿命。西安市一环内由于其传统道路格局限制,人流量车流量巨大,再加上目前进行的旧城改造工程,其环境污染的程度要比其他地区更加严重。所以利用道路绿化改善道路环境和道路景观已成为当务之急。本文的主要内容共分为五个部分：第一部分是绪论,主要提出西安市一环内道路绿化问题的研究背景和研究目的。在西安市提出实现“生态城市”和“国际化大都市”的建设目标过程中,城市道路绿地作为其中的重要影响因素,其发挥的作用不容忽视。因此,通过对西安市一环以内的绿地面积及绿地率的计算对比存在的差距,从而提出研究此区域道路绿化问题的必要性。第二部分主要介绍了西安市的道路绿化状况,即在分析西安市的区位条件和地理环境条件的基础上,追溯了西安市道路绿化的历史沿革；然后结合西安市一环内目前的道路格局,详细统计了部分街道行道树树种的生态习性、景观用途以及所在街道分布,并分析总结出其树种选择的特点。第三部分和第四部分是全文的重点,即从道路绿地建设具备的环境保护功能、交通安全功能、景观设计功能以及植物养护管理四个方面出发对西安市一环内的道路绿化存在的问题进行了具体的分析,并相应的提出了可操作性较强的意见和建议,为此区域道路绿化的规划与设计提供一定的参考。第五部分是结语,即对全文进行总结并提出了研究展望。西安市的城市绿地建设是一项涉及面很广的系统工程,而一环以内的道路绿化只是其中的一小部分。希望西安市今后的城市绿地建设能够在调整和更新的基础上充分利用其优越的自然地理环境条件,早日建成为人居环境舒适优美的生态之城和国际化大都市。
[Abstract]:Urban green space is the only living infrastructure of a city. It is the basis of harmony between man, city and nature. It is also the key element to perfect the living environment of the city and maintain the balance of natural ecology. Ecological construction of urban green space is an important part of urban green space system planning and urban planning in recent years. It is not only the basic requirement of social development, but also the trend of modern urban development. In recent years, due to the continuous development of urban construction, people have higher and higher requirements for road traffic greening, which not only requires its safety, speed, economy, convenience and comfort, but also requires it to give people spiritual enjoyment. At the same time, it is friendly to the surrounding environment and can satisfy the urgent need for people to breathe fresh air and enjoy quiet at any time. As far as the ecological impact on a city is concerned, if trees, fruit trees, shrubs, dwarf forests, forages, flowers and flowers are planted along both sides of urban roads, not only can we beautify the environment, purify the air, absorb noise, and improve travel conditions, It is good for driving safety, and can stabilize the roadbed, shade the pavement and prolong the service life of the road. Because of the restriction of the traditional road pattern, the traffic flow in Xi'an is huge, and the environmental pollution is more serious than that in other areas. Therefore, the use of road greening to improve the road environment and road landscape has become a top priority. The main contents of this paper are divided into five parts: the first part is the introduction, mainly put forward the research background and purpose of the road greening in Xi'an. In the process of realizing the construction goals of "ecological city" and "international metropolis" in Xi'an, urban road green space is an important influencing factor, and its function can not be ignored. Therefore, it is necessary to study the problem of road greening in Xi'an by comparing the difference between the calculation of green space area and green space rate within the first ring of Xi'an city. The second part mainly introduces the status of road greening in Xi'an, that is, on the basis of analyzing the location and geographical environment of Xi'an, the historical evolution of road greening in Xi'an is traced back. Combined with the current road pattern in Xi'an, the ecological habits, landscape uses and distribution of some street tree species are analyzed in detail, and the characteristics of tree species selection are analyzed and summarized. The third and fourth parts are the emphases of the full text, that is, the environmental protection function and the traffic safety function of the road green space construction. Based on the landscape design function and plant maintenance management, the paper analyzes the existing problems of road greening in Xi'an City, and puts forward some suggestions and suggestions. Therefore, the planning and design of regional road greening provides a certain reference. The fifth part is the conclusion, that is to sum up the full text and put forward the research prospect. The construction of urban green space in Xi'an is a systematic project involving a wide range of aspects, and the road greening within one link is only a small part of it. It is hoped that the construction of urban green space in Xi'an in the future can make full use of its superior natural geographical environment conditions on the basis of adjustment and renewal, and become a comfortable and beautiful ecological city of human settlements and an international metropolis as soon as possible.
