Landscape Design of Urban Residential Communities Toward Carbon Neutrality Goals: A Case Study of Taigu District, Jinzhong City, Shanxi Province, China

As the climate crisis intensifies, achieving carbon neutrality has become a global consensus. Urban residential communities constitute a vital component of cities. The carbon sequestration function of residential community green space systems plays a significant role in reducing urban CO₂ levels. By combining a literature review and field investigation, this paper focuses on urban residential communities in Taigu District, Jinzhong City, Shanxi Province, China. These communities are categorized into three types based on factors such as green space area, plant cultivation and growth, and design. The analysis identifies negative impacts on carbon sequestration efficiency in terms of spatial layout, green landscape design, plant growth and maintenance, and plant configuration. A design approach integrating "vertical (roof-to-ground) and horizontal (planar) dimensions" and "ecology-technology-human participation" is proposed. This aims to achieve carbon sequestration increments across different community types, thereby reducing the concentration of carbon dioxide in the air. At the same time, landscape quality and residents' experience are also taken into account. This strategy provides a reference design methodology for areas with scarce green space resources and high carbon dioxide emissions.
