摘要 以丹陽市万善公园改造设计为例,通过实地调研和问卷调查,采用定量统计和定性分析的方法,旨在探讨城市公园植物配置应用效果和生态稳定性。结合“城市双修”建设需要,利用城市生态学原理和中国植物文化,增加乡土植物、地被植物和水生植物的种类,扩大边缘植物景观尺度,优化植物群落和生态结构,提出植物配置可行性优化建议,促进人与自然、城市与自然的和谐共生。

Abstract Taking the reconstruction design of Wanshan Park in Danyang, Jiangsu as an example, through field investigation and questionnaire survey, the methods of quantitative statistics and qualitative analysis were adopted,the purpose of this study was to explore the effect of plant configuration and ecological stability in urban parks. To meet the needs of “urban doublemaintenance” construction, the principles of urban ecology and Chinese plant culture were used to increase the species of native plant,ground cover plant and hydrophyte, to expand the scale of marginal plant landscape, and to optimize the plant community and ecological structure. The feasibility optimization of plant configuration was put forward to promote the harmonious coexistence between human and nature, city and nature.

党的“十八大”提出城市建设要牢固树立“创新、协调、绿色、开放、共享”的发展理念,将“城市修复”和“生态恢复”作为城市发展建设的主要任务,推进生态文明建设,努力打造成为和谐宜居、富有活力、各具特色的现代化城市[1-3]。举措之一是完善城市绿地系统,推进生态廊道建设,因地制宜建设湿地公园、雨水花园等海绵绿地,推广老旧公园改造,提升存量绿地品质和功能[4-7]。推行生态绿化方式,提高乡土植物和地被植物的应用比例,优化植物群落结构。
随着生态文明建设步伐的加快,广大市民对“城市双修”有了更多的关注,特别是城市旧公园的改造与生态修复。丹阳市万善公园是最好的历史见证,在新一轮“城市双修”建设中,拆除了厚重的建筑围墙,通过合理设计增加了大量的绿色植被,恢复了滨水绿地生态系统,打通了与运河的“有机对话”,扩大了景观视野范围,从而更好地发挥万善公园的生态环境效益和公共绿地的有效使用率。……
