一般而言，城市的碳中和目标强调植被，特别是自然群落和生态系统的作用。到目前为止，全市范围的碳库评估侧重于土地覆盖和土地利用类型，城市树木的作用受到特别重视。然而，在城市地区的各种植被类型的固碳和储存（CSS）的能力，以及他们的潜力，以提高城市碳汇仍然在很大程度上未经审查。规划和管理城市绿色基础设施（GI）需要一个明智的气候战略的CSS，提供了一个可扩展的栖息地和个别植物物种之间的联系。因此，本研究的重点是城市植被的CSS能力，通过专题审查，并确定在寒冷气候城市的CSS影响的关键因素。该研究进一步强调，大气固碳的基础在于个别植物的有利生长和气孔功能。单个植物的CSS构成了城市GI及其提供的生态系统服务的基础。此外，城市植被的生长受到各种城市生长条件的影响，这些条件随着居民对植被的管理、使用和改造而不断变化。虽然土壤是碳的主要储存库，但植被在将大气中的碳转化为土壤有机碳方面的作用至关重要。在这项研究中，与;影响CSS的关键驱动因素的理解，我们定义了一个框架，碳为基础的植被类型学和讨论的生长条件和维护实践方面的CSS能力的不同植被类型之间的联系。该框架为城市植被的CSS进一步跨学科研究提供了概念基础，例如，CSS能力建模和城市植被的生命周期评估。它还通过为参与地理信息系统的多专业行为者制定实用和基于科学的建议，支持气候明智的规划，设计和维护。
Generally, the carbon neutrality targets of cities underline the role of vegetation especially nat-ural biotopes and ecosystems. City-wide carbon pool assessments have so far focussed on land cover and land use types, with the role of urban trees receiving particularly significant attention. However, the carbon sequestration and storage (CSS) capacity of various vegetation types in urban areas as well as their potential to enhance urban carbon sinks remains largely unexamined. Planning and managing urban green infrastructure (GI) requires a climate-wise strategy of CSS that provides a scalable link between habitats and individual plant species. Therefore, this study focusses on the CSS capacity of urban vegetation through a thematic review and identifies the key elements influencing CSS in cold-climate cities. The study further highlights that the basis for atmospheric carbon sequestration lies in the favourable growth and stomatal functioning of an individual plant. The CSS of individual plants forms the basis for urban GI and the ecosystem services they provide. Moreover, the growth of urban vegetation is affected by diverse urban growing conditions, which are under continuous change as vegetation is managed, used and modified by residents. Although soils are a major storage for carbon, the role of vegetation in transforming carbon from the atmosphere into soil organic carbon is fundamental. In this study, with; the understanding of the key drivers influencing CSS, we define a framework for a; carbon-based vegetation typology and discuss the links between growing conditions and maintenance practices with regard to the CSS capacity of diverse vegetation types. This framework provides a conceptual basis for further interdisciplinary research into the CSS of urban vegetation, for example, for CSS capacity modelling and life cycle assessment of urban vegetation. It also supports climate-wise planning, design and maintenance by formulating practical and science-based recommendations for multi-professional actors engaged in GI.
