【摘要】：南京环紫金山绿道植物景观丰富多样,总体可归纳为"点、线、面"三种景观类型。"点"包括绿道独立景点、公园、广场及绿道出入口节点等;"线"指环紫金山绿道及其周边一定范围内的带状绿地;"面"则是指环紫金山绿道与城市所结合形成的大型景观体系。而"线"(即环紫金山绿道)是串联所有"点"与"面"的关键所在。本文将以南京环紫金山绿道为研究对象,运用植物群落学、风景园林学、环境行为学以及景观评价等理论和方法,对环紫金山绿道绿地中相对稳定的28个典型植物群落进行实地调查,记录样地的植物种类、数量特征和生长情况,并选取14个典型样地进行了平面图绘制,分析环紫金山绿道植物景观的配置模式、数量组成和群落特征,再从观赏特性角度,从色彩、嗅觉和季相演替方面,对环紫金山绿道植物景观的观赏特性进行分析;然后采用美景度评价法(SBE法)对环紫金山绿道植物景观进行美景度评价;最后在此基础上,提出环紫金山绿道植物景观优化策略。研究内容和结论包含以下几个方面:1、通过对28个样地的实地调查与数据统计,可以看出植物景观类型多为郁闭型与园林型,植物种植模式多数为自然式种植;植物群落较为均衡,常绿植物与落叶植物相互搭配种植;样地多为乔灌草结合的复合型植物配置模式,层次分明,空间结构丰富多变。2、通过所调研的样地,汇总得出环紫金山绿道植物物种组成共60科117属157种,其中应用较多的科集中在蔷薇科、木犀科、木兰科、百合科、忍冬科、豆科、冬青科、豆科等。然后计算各种乔木出现的相对多度、相对频度、相对显著度和灌木出现的相对频度、相对盖度,最后得出环紫金山绿道各种乔、灌木出现的重要值。乔木层重要值排前5位的为:紫薇、雪松、鸡爪槭、香樟、紫叶李。灌木层重要值排前5位的为:桂花、红叶石楠、红花(?)木、洒金桃叶珊瑚、毛鹃。3、从植物景观的色彩特性、嗅觉特性、季相变化特征三个方面来讨论不同观赏特性的园林植物在环紫金山绿道重要节点中的应用。对不同观赏特性植物的合理搭配是营造丰富植物景观的关键。4、对环紫金山绿道的植物景观进行充分调查的基础之上,选取18样地作为景观美景度的评价对象,通过对不同样地SBE值研究以及不同得分样地的对比分析,优化SBE值计算方法,分析植物景观美景度的影响因素,进而提出相关优化建议.本文将通过对环紫金山绿道植物景观的研究及评价,对环紫金山绿道植物景观提出优化提升策略的同时,也为以后南京城市绿道重要节点植物景观的营造提供参考。
[Abstract]:The plant landscape of Zijinshan Green Road around Nanjing is rich and diverse, which can be summed up as "point, line and surface" three landscape types. The "dot" includes the green road independent scenic spot, the park, the square and the green road entrance and exit node and so on; "the line" the ring Zijinshan green road and its surrounding certain area in the belt green space; "face" is a large-scale landscape system formed by the combination of the ring Zijinshan Green Road and the city. The line is the key of all points and faces. In this paper, we will use the theories and methods of plant community, landscape architecture, environmental behavior and landscape evaluation to study the Zijinshan Green Road around Nanjing. A field investigation was carried out on 28 typical plant communities in the greenbelt of the Green Road around Zijinshan. The plant species, quantitative characteristics and growth were recorded, and 14 typical plots were plotted. This paper analyzes the plant landscape configuration model, quantity composition and community characteristics of the green road around Zijin Mountain, and analyzes the ornamental characteristics of the plant landscape from the angle of ornamental characteristics, color, smell and seasonal succession. Then the beauty degree evaluation method (SBE method) was used to evaluate the plant landscape of the green road around Zijinshan, and on the basis of this, the optimization strategy of plant landscape of the green road around purple hill was put forward. The research contents and conclusions include the following aspects: 1. Through the field investigation and data statistics of 28 plots, we can see that the plant landscape type is mostly closed type and garden type, and most of the plant planting mode is natural type planting; The plant community is more balanced, evergreen plant and deciduous plant are planted with each other; Most of the sample plots are composed of trees, shrub and grass, with distinct layers and rich and changeable spatial structure. 2. Through the sample plots investigated, it is concluded that there are 157 species in 117 genera and 60 families of plants in the Green Road of Zijinshan Mountain, which are composed of 60 families, 117 genera and 157 species. The most applied families are Rosaceae, Oleaceae, Magnoliaceae, Liliaceae, Lonicera, Leguminosae, Holly, Leguminosae, etc. Then the relative abundance, relative frequency, relative prominence and relative coverage of various trees and shrubs are calculated. Finally, the important values of the emergence of various trees and shrubs in the Green Road around Zijinshan are obtained. The top five important values of Arbor layer are: Lagerstroemia, Cedar, Acer maple, Cinnamomum camphora, Purple Plum. The top five important values of shrub layer are Osmanthus osmanthus, Photinia koraiensis, Carthamus tinctorius (?) This paper discusses the application of landscape plants with different ornamental characteristics in the important nodes of the Green Road around the Zijinshan Mountain from three aspects: the color characteristics of plant landscape, the characteristics of smell, and the characteristics of seasonal changes. The reasonable collocation of plants with different ornamental characteristics is the key to create rich plant landscape. 4. On the basis of investigating the plant landscape of the Green Road around Zijinshan Mountain, 18 plots are selected as the evaluation objects of landscape beauty. Through the study of different SBE values and the comparative analysis of different score samples, the calculation method of SBE value was optimized, and the influencing factors of plant landscape beauty were analyzed, and the related optimization suggestions were put forward. Through the research and evaluation of the plant landscape of the ring purple mountain green road, this paper puts forward the optimization and promotion strategy for the plant landscape of the ring purple mountain green road, and also provides a reference for the construction of the plant landscape of the important node of the Nanjing city green road in the future.
