Investigation And Research On The Planting Landscape Of The Morden Urban Squares In Nanjing

Squares in Nanjing and the rise of fiery marks not only the people to return to nature philosophy in real life applications, but also marks the Nanjing people’s material and cultural life level steady increase. Urban Square is the city life of plant community and one of the most closely related sites, about urban square greening plant community diversity to improve city life quality of residents have an important role in. With the development of modern urban landscape development, use of plant landscape ecology and art the principle of building a number of species rich, complex structure, seasonal variation characteristic is obvious, outstanding regional features of plant community, is a modern urban green space plant landscape research emphases in the future, but also the main contents of the thesis.The author in2010to2012in Nanjing city built after2000or transformation of the representative of the ten modern urban squares greenbelt landscape conducted field investigations, extensive search of literature and questionnaire survey, from the plant landscape and ecology perspective on these square the drawbacks and defects are analyzed, on the Nanjing urban modern urban square in all plants, including Joe, irrigation, being and other species, growth, plant pattern, seasonal plant landscape to make investigation and evaluation of modern urban square, Nanjing urban plant landscape characteristics and deficiency of the summary, put forward to improve opinion and proposal, draw the following conclusions:The results show that:1. The city of Nanjing in ten modern urban square has cultivated and wild plant a total of139species, belonging to57families and107genera. The woody plants of83genera,112subtotal44:including56species of arbor, belonging to24families,44genera;56shrub species, belonging to25families,42genera. Herbaceous plants of25genera and27species15. Trees, shrubs, herbaceous plants with the total ratio of about2:2:1. Square total native trees49, accounted for the proportion of35.3%plant species. Seasonal characteristics of plants in the square, basically have King seasons, and the four seasons landscape distribution more uniform.2. Effects of Nanjing modern urban square landscape index and the comprehensive evaluation criterion layer factor sorting:community structure species composition seasonal plant landscape. Survey of the10Nanjing modern urban square plant landscape comprehensive evaluation index is more than70%square occupies the majority, the overall situation is good. Among them, a total of4grade4class Ⅱ square,square, square2III. 3. The plant landscape of10Nanjing morden urban squares, community structure (B1) and common problems in partial squares tree layer and herb layer. The vast majority of squares species composition (B2) of the common problems are species evenness is not enough. While the10squares four seasons landscape plants (B3) common problems is the fall winter season has obvious ornamental plants less or ornamental characteristics was not obvious, and the lack of Some Quaternary period of landscape plants. Analysis of the seasonal change of the advantage and shortage, and put forward a number of optimization suggestions. Through the analysis of above investigation squares features, reach Nanjing modern urban squares of some common optimization direction and suggestion.
