南京地处长江中下游平原,气候温和、湿润,为植物造景提供了良好的发展空间。玄武湖又是南京大规模的市民公园,研究玄武湖的色叶树的应用对城市发展中色叶树的利用有着指导性的意义。在三个时间段,通过对玄武湖公园四个主要景点的色叶树进行调查,总结出呈色特点优缺点各有三个方面:植物群体效果良好、黄叶植物呈色良好和常绿落叶比重合理;红叶树种呈色不明显、单株效果不稳定和变色时间短。并且分析原因,进而得出玄武湖公园优化色叶树种在引种、养护和造景三方面的使用策略。
Nanjing is located in the middle and lower reaches of the Yangtze River plain, mild climate, moist, landscaping for the plant provides a good space for development. Xuanwu Lake is also a large-scale public park in Nanjing. The study on the use of color-leaf trees in Xuanwu Lake has guiding significance for the utilization of color-leaf trees in urban development. In three periods, through the investigation of the colored leaf trees in the four main scenic spots of Xuanwu Lake Park, the advantages and disadvantages of the colored features are summarized in three aspects: the plant population is good, the color of yellow-leaf plants is good and the proportion of evergreen leaves deciduous Reasonable; red leaf tree species was not obvious, the effect of instability and short color change time. And analyze the reasons, and then come to Xuanwu Lake Park optimized color planted tree species in the introduction, conservation and landscaping three aspects of the strategy.
