【摘要】：随着我国形成的“绿道热”,南京在绿道建设上进行了大胆的尝试和探索。本论文以南京3条不同功能属性的绿道为研究对象,通过实地调研,探究南京绿道的植物群落特征、常见群落配置模式、植物景观特色和植物造景中存在问题,并根据南京绿道植物景观的美景度评价结果构建出绿道植物景观的美景度预测模型。最后根据存在问题提出针对性的景观优化建议。主要研究成果如下:1、在南京绿道植物群落调查中,对南京紫金山绿道、古城墙绿道、滨江绿道共计66.5km长的绿道区段进行植物群落调查,调查共设置样地53个。通过总体普查和样方调查相结合的方法,对南京绿道的植物种类特征、植物类型组成、季相结构、数量特征和多样性五方面的特征进行分析,并进行三条绿道间的横向对比分析。结果显示,总体在这五方面的特征上,紫金山绿道在各方面要优于古城墙绿道,古城墙绿道优于滨江绿道。2、将53个样地依据其区域位置和群落特征划分为疏林草地型群落、密林型群落、滨水型群落和道路型群落4种类型。运用美景度评价法,对53个样地中优选出的20个样地进行景观评价,得出四种类型植物景观中SBE值评价结果。同时,通过对影响植物景观质量要素的量化与分解,建立了绿道植物景观美景度评价模型:SBE=-451.233+91.225×植物季相及色彩+30.421×植株形态+40.08×植物健康状况+100.26×植物群落丰富度+84.139×植物群落郁闭度+88.935×植物群落层次感+8.563×景观韵律节奏+11.752×景观协调对比性+44.625×安全度。3、分析南京绿道的景观现状,对南京绿道四种群落类型的景观特点和设计手法进行了总结;对景观评价中四种类型植物群落得分最高的优秀样地进行详细分析,包括绘制样地平面示意图、统计群落物种信息、分析造景特点、配置模式等;最后,总结出南京绿道四种类型群落中常见的植物配置模式。4、在上述研究的基础上,归纳总结南京绿道植物景观的特色及不足,并针对不足提出了相应的优化建议,以期为今后南京绿道植物的景观优化和发展提供参考和借鉴。
[Abstract]:With the formation of "Green Road fever" in China, Nanjing has made a bold attempt and exploration in the construction of Green Road. In this paper, three green roads with different functional attributes are taken as the research objects. Through field investigation, the plant community characteristics, common community allocation models, plant landscape characteristics and plant landscape problems in Nanjing Green Road are investigated. Based on the results of landscape evaluation of plant landscape in Nanjing Green Road, a model for predicting the beauty of green road plant landscape is established. Finally, according to the existing problems, some suggestions on landscape optimization are put forward. The main research results are as follows: 1. In the plant community investigation of Nanjing Green Road, the plant communities of the green road section of Zijinshan, ancient city wall and Binjiang green road were investigated, and 53 plots were set up. Through the method of general survey and sample investigation, the characteristics of plant species, plant type composition, seasonal phase structure, quantitative characteristics and diversity of Nanjing Green Road are analyzed. And carries on the horizontal contrast analysis between the three green roads. The results showed that the Zijinshan Green Road was superior to the Old Wall Green Road in all aspects, and the Old Wall Green Road was superior to the Binjiang Green Road. The 53 plots were divided into sparse forest and grassland communities according to their regional location and community characteristics. There are four types of dense forest community, waterfront community and road type community. Using the method of beauty degree evaluation, the landscape of 20 plots selected from 53 plots was evaluated, and the evaluation results of SBE values in four types of plant landscape were obtained. At the same time, by quantifying and decomposing the factors affecting plant landscape quality, The evaluation model of landscape beauty of green road plants was established. The model of landscape beauty of green road plant was established: 1: SBEM-451.233 91.225 脳 plant seasonal phase and color 30.421 脳 plant shape 40.08 脳 plant health status 100.26 脳 plant community richness 84.139 脳 plant community canopy density 88.935 脳 plant community stratification 8.563 脳 landscape Rhythmic Rhythm 11.752 脳 Landscape Coordination contrast 44.625 脳 Safety degree. 3. The landscape status of Nanjing Green Road is analyzed. The landscape characteristics and design techniques of four community types in Nanjing Green Road were summarized, and the excellent plots with the highest score of plant communities in landscape evaluation were analyzed in detail, including drawing the plot plan. Statistics of community species information, analysis of landscape characteristics, configuration patterns, etc. Finally, the common plant allocation model. 4, in four types of communities of Nanjing Green Road, on the basis of the above research, This paper summarizes the characteristics and deficiencies of plant landscape in Nanjing Green Road, and puts forward corresponding suggestions for optimization of plant landscape in Nanjing Green Road in the hope of providing reference and reference for landscape optimization and development of plants in Nanjing Green Road in the future.
