【摘要】：城市林蔭道景觀是城市景觀重要組成部分,它的景觀效果直接反映城市的整體風貌。本文在城市化、生態(tài)園林城市建設興起以及林蔭道作為生態(tài)園林城市評判的重要指標的背景下,對南京市林蔭道景觀進行評價研究。通過對大量相關研究資料的總結和分析,提出林蔭道的概念為：位于城市城區(qū)內,兩側種植一排以上大、中喬木作為行道樹,形成較高綠化覆蓋率和連續(xù)的林蔭空間,具備交通、景觀游憩、生態(tài)效益和文脈繼承等綜合功能的城市道路。分別按道路性質、道路結構、景觀類型、使用主體為不同分類依據(jù)進行分類,按道路性質分：交通類、生活類；按道路結構分為：一板式、二板式、三板式、四板式；按景觀類型分為：自然風景類、商業(yè)類、生活類、歷史文化類、復合林蔭大道；按使用主體分為：人車混雜型林蔭道、步行式林蔭道。運用層次分析法(AHP)構建南京市林蔭道景觀綜合評價體系,從植物景觀、環(huán)境效益、空間協(xié)調、交通功能、硬質景觀融合、歷史文化六個方面對林蔭道景觀進行評價。以南京市園林局2013公布的100條擬建名單為基礎,從中選擇85條代表性道路進行調查,按照綜合得分將其分為五級,評分結果表明,南京市林蔭道中,景觀綜合評價等級為Ⅰ級的道路共8條,占9%,Ⅱ級道路共21條,占26%,Ⅲ級道路共45條,占52%,Ⅳ級道路共10條,占12%,Ⅴ級道路僅1條,占1%,評分結果顯示南京市林蔭道整體景觀質量較好,自然風景類、歷史文化類林蔭道景觀質量最好,商業(yè)類林蔭道次之,復合式林蔭道得分兩級分化,生活類林蔭道比例最大,景觀質量整體一般。從道路板式、行道樹應用特征、彩葉、開花植物應用情況、垂直結構、優(yōu)勢種群年齡結構分析其基本特征,進而根據(jù)評分結果分析總體得分情況特征,新老城區(qū)景觀特征、各準則層在不同林蔭道景觀中的表現(xiàn)以及五種景觀類型林蔭道得分情況,得出不同道路存在的具體問題和需要提升的方面。最后根據(jù)調研和評分結果對目前南京市林蔭道所存在的具體問題進行歸類總結,并提出合理的優(yōu)化方案,為南京市林蔭道建設發(fā)展提供參考和建議。
[Abstract]:Urban avenue landscape is an important part of urban landscape, its landscape effect directly reflects the overall style of the city. In this paper, under the background of urbanization, the rise of ecological garden city construction and the street as an important index of the evaluation of ecological garden city, this paper evaluates the landscape of the street in Nanjing. Based on the summary and analysis of a large number of related research data, the concept of the mall is put forward as follows: located in the urban area, with more than one row planted on both sides, the middle tree is used as the street tree, which forms a higher green coverage rate and a continuous tree-shade space. Urban roads with comprehensive functions such as transportation, landscape recreation, ecological benefits and cultural heritage. According to the road nature, the road structure, the landscape type, the main body is the different classification basis, divides according to the road nature: the transportation class, the life class, according to the road structure divides into: one plate type, two board type, three board type, four plate type; It is divided into natural scenery, commercial, life, history and culture, compound boulevard according to landscape type; The comprehensive evaluation system of the street landscape in Nanjing was constructed by using the analytic hierarchy process (AHP). The landscape of the mall was evaluated from six aspects: plant landscape, environmental benefit, space coordination, traffic function, hard landscape fusion, history and culture. Based on a list of 100 proposed projects published by Nanjing City Park and Forestry Bureau in 2013, 85 representative roads were selected for investigation. According to the comprehensive scores, they were divided into five levels. The score shows that, in the streets of Nanjing, There are 8 roads of grade 鈪，
