摘　　要：城市历史公园作为承载城市记忆和提供自然休憩的传统城市场所,是市民群众日常生活中必不可少的一部分。同时,历史公园中多年形成的高大乔木随时可能因过度开敞和下层植被的调整而降低其组团的固碳作用。因此,为了在历史公园改造中优化高大乔木植物团块的碳汇能力,文章以西安地区三个近年改造完成的城市历史公园内高郁闭度植物空间中选择样块,总结出历史公园改造中高效率的碳汇模型。在咸阳渭滨公园改造项目中使用了土壤改良优化基层固碳能力、利用高碳汇能力植物进行林下空间植物配置、降低植物养护碳排放的全过程低碳模式,总结出适用于城市历史公园高郁闭度环境下低扰动、高固碳的林下灌—花、灌—草的植物生境营造模式及其养护经验,以期为后续设计、施工及养护研究提供依据。Urban historic parks,as traditional urban marketplaces that bear the city's memories and provide natural respite,are an essential part of the daily lives of citizens.At the same time,the tall trees that have developed over many years in historic parks as important carbon-sequestering units are often adjusted in renovation project with functions and plant spaces,which may reduce their carbon sequestration effect due to excessive openness and adjustment of understory vegetation.Therefore,in order to optimize the carbon sequestration capacity of tall tree clusters in historic park renovation,this paper selects samples from high-canopy plant spaces in multiple recently renovated urban historic parks in Xi'an and Xianyang.We summarize an efficient carbon sequestration model in historic park renovation.In the Xianyang Weibin Park renovation project,we use soil improvement to optimize the carbon sequestration capacity at the base level,utilize plants with high carbon sequestration capacity for understory planting and configuration,and implement a low-disturbance,high-carbon sequestration low-carbon mode by reducing carbon emissions from plant maintenance.We summarize a plant habitat creation mode for understory shrubs-flowers and shrubs-grasses that is suitable for the high-canopy environment in urban historical parks and their maintenance experience,with the aim of providing a basis for subsequent design,construction,and maintenance research.
