摘　　要：“双碳”背景下,公园在城市减碳增汇方面展现出重要作用,在城市碳循环中被赋予了碳平衡职能。但城市公园在提供休闲游憩服务的同时,也伴随着大量的碳排放。为揭示城市公园是否为有效的碳汇体,通过构建城市公园碳平衡评估框架,评估南京15个城市公园的年度碳平衡情况,明确影响城市公园碳平衡的关键景观要素指标。结果显示,不同城市公园的年度碳平衡情况存在差异性,绝大多数公园是“碳源”;公园的面积越大,植被覆盖度越高,其碳吸收能力也越强,照明、绿色废弃物处理和建筑运维是主要来源;绿地率、硬质面积和建筑面积三个指标与碳平衡的实现密切相关。对城市碳平衡目标的达成具有积极的意义,不仅可为城市公园的更新与改造提供数据支持,也能够为运维管理的优化提供参考。In the context of“dual carbon”,parks have shown an essential role in reducing carbon emissions and increasing sinks in cities and have been assigned the function of carbon balancing in the urban carbon cycle.However,while providing leisure and recreational services,urban parks are also accompanied by many carbon emissions.This study aims to reveal whether urban parks are adequate carbon sinks.By constructing a framework for evaluating the carbon balance of urban parks,we assessed the annual carbon balance of 15 urban parks in Nanjing.We used a machine learning method to clarify the key landscape element indicators that affect the carbon balance of urban parks.The results show that there are differences in the annual carbon balance of different urban parks,and most of the parks are“carbon sources”;the larger the area of the park,the higher the vegetation coverage,the stronger the carbon absorption capacity,and lighting,green waste treatment and building operation and maintenance are the primary sources;the three indicators of green space rate,hard surface area,and building area are closely related to the realization of the carbon balance.The three indicators of green space rate,complicated area,and building area are closely related to realizing carbon balance.This study is of positive significance to the achievement of carbon balance in the city,which provides data support for the renewal and renovation of urban parks and provides a reference for the optimization of operation and maintenance management.
