摘要
以南京市典型景观大道为研究对象,采用无人机航拍、实地调查及GIS技术获取道路绿地信息并建立数据库,结合生态学理论,量化评价道路绿化带的植物景观特征,针对配置模式的不足之处提出优化策略,以期完成对南京市道路绿化现状的评价和植物景观设计理论的提升。结果表明:南京市道路绿化植物以乡土树种为主、地带性明显;配置模式因地制宜,呈现多元化;园林美学思想和生态设计理念的引入使景观特色突出。但也存在老城区植物种类单一;新优植物品种应用薄弱;为短期内打造良好景观,植物生长规律考虑欠佳;部分路段群落稳定性差等问题。建议在今后的城市道路绿化景观优化调整中,绿化材料建议以地方优势种和乡土树种为主,适当引入新优品种;配置模式因地制宜,注重自然式植物群落的营造、生态设计理念和园林美学思想的融合;将城市建于自然,以形成独具特色的城市生态文明景观大道作为城市道路绿地建设发展的方向。
The typical landscape avenue of Nanjing was taken as the research object,the aerial photography,field survey and GIS technology of the drone were used to obtain the road green space information and established the database.Combining ecological theory,quantitatively evaluated the plant landscape characteristics of road greenbelts,and proposed optimization strategies for the shortcomings of the configuration model.In order to complete the evaluation of the current situation of road greening in Nanjing and the improvement of the theory of plant landscape design.The results showed that the plants in the green belt of Nanjing city were native,the distribution of plants was significant.Plant configuration patterns were diverse and adapted to local conditions.The landscape was distinctive,because of the introduction of garden aesthetics and ecological design concepts.But there were still some problems.Single plant species were planted in old town,new and excellent plant varieties were less used,plant community were unstable in some sections,in order to create good landscapes in the short term,the plant growth law was considered poor.Based on these observations,when the urban road landscapes would be adjusted in the future,local dominant species and native plant can be used as main greening materials,and properly combined with new varieties.The construction of natural plant communities,the integration of ecological design ideas and garden aesthetics should be emphasized.Unique urban roads of ecological landscape will be built by introducing nature.These will be the direction of urban roads green space construction and development.
