【摘要】:城市綠地是城市惟一有生命的基礎(chǔ)設(shè)施,是人、城市、自然和諧的基礎(chǔ),也是完善城市生存環(huán)境和維持自然生態(tài)平衡的關(guān)鍵要素。城市綠地建設(shè)的生態(tài)化是近幾年城市綠地系統(tǒng)規(guī)劃和城市規(guī)劃的重要部分,它既是社會(huì)發(fā)展的基本要求,也是現(xiàn)代城市發(fā)展的趨勢(shì)。近年來(lái),由于城市建設(shè)的不斷發(fā)展,人們對(duì)道路交通綠化的要求越來(lái)越高,不僅要求其安全、快捷、經(jīng)濟(jì)、方便、舒適,而且要求其能給人以精神上美的享受,同時(shí)對(duì)周?chē)h(huán)境友好,能滿(mǎn)足人們隨時(shí)呼吸到新鮮空氣和享受安靜等作用的迫切需要。從對(duì)一座城市的生態(tài)影響上來(lái)看,如果沿城市道路兩側(cè)種植喬木、果樹(shù)、灌木、矮林、牧草、花卉,營(yíng)造小型園林,不但可以美化環(huán)境、凈化空氣、吸收噪音、改善行旅條件、有利于行車(chē)安全,而且可以穩(wěn)定路基,遮蔭路面,延長(zhǎng)道路使用壽命。西安市一環(huán)內(nèi)由于其傳統(tǒng)道路格局限制,人流量車(chē)流量巨大,再加上目前進(jìn)行的舊城改造工程,其環(huán)境污染的程度要比其他地區(qū)更加嚴(yán)重。所以利用道路綠化改善道路環(huán)境和道路景觀(guān)已成為當(dāng)務(wù)之急。 本文的主要內(nèi)容共分為五個(gè)部分: 第一部分是緒論,主要提出西安市一環(huán)內(nèi)道路綠化問(wèn)題的研究背景和研究目的。在西安市提出實(shí)現(xiàn)“生態(tài)城市”和“國(guó)際化大都市”的建設(shè)目標(biāo)過(guò)程中,城市道路綠地作為其中的重要影響因素,其發(fā)揮的作用不容忽視。因此,通過(guò)對(duì)西安市一環(huán)以?xún)?nèi)的綠地面積及綠地率的計(jì)算對(duì)比存在的差距,從而提出研究此區(qū)域道路綠化問(wèn)題的必要性。 第二部分主要介紹了西安市的道路綠化狀況,即在分析西安市的區(qū)位條件和地理環(huán)境條件的基礎(chǔ)上,追溯了西安市道路綠化的歷史沿革;然后結(jié)合西安市一環(huán)內(nèi)目前的道路格局,詳細(xì)統(tǒng)計(jì)了部分街道行道樹(shù)樹(shù)種的生態(tài)習(xí)性、景觀(guān)用途以及所在街道分布,并分析總結(jié)出其樹(shù)種選擇的特點(diǎn)。 第三部分和第四部分是全文的重點(diǎn),即從道路綠地建設(shè)具備的環(huán)境保護(hù)功能、交通安全功能、景觀(guān)設(shè)計(jì)功能以及植物養(yǎng)護(hù)管理四個(gè)方面出發(fā)對(duì)西安市一環(huán)內(nèi)的道路綠化存在的問(wèn)題進(jìn)行了具體的分析,并相應(yīng)的提出了可操作性較強(qiáng)的意見(jiàn)和建議,為此區(qū)域道路綠化的規(guī)劃與設(shè)計(jì)提供一定的參考。 第五部分是結(jié)語(yǔ),即對(duì)全文進(jìn)行總結(jié)并提出了研究展望。西安市的城市綠地建設(shè)是一項(xiàng)涉及面很廣的系統(tǒng)工程,而一環(huán)以?xún)?nèi)的道路綠化只是其中的一小部分。希望西安市今后的城市綠地建設(shè)能夠在調(diào)整和更新的基礎(chǔ)上充分利用其優(yōu)越的自然地理環(huán)境條件,早日建成為人居環(huán)境舒適優(yōu)美的生態(tài)之城和國(guó)際化大都市。
[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.
