Low-carbon, green, and sustainable development has become a central theme in territorial spatial planning and governance in the era of stock. Township areas, as key regions for carbon emissions in China, play a crucial role in carbon reduction and control, and are vital governance zones that are closely related to territorial spatial protection and development. However, existing research has not yet comprehensively integrated the goals of “carbon peaking” and “carbon neutrality” into territorial spatial planning, with insufficient linkage to specific spatial strategies. In particular, research at the micro-scale of rural and township areas is still nascent, hindering effective guidance for spatial optimization. This study first examines the hierarchical role of the goals within the territorial spatial planning governance system and develops a carbon assessment model for rural and township areas. Then, using Changshaoying Township, located in the ecological conservation zone of the capital, as a case study, the research delineates boundaries for protection and utilization based on ecological significance assessments. Through forest resource evaluation and visual accessibility analysis, this study proposes site selection and decision-making methods that focus on ecological restoration, planting structure optimization, and phased project implementation, all aimed at achieving carbon reduction and carbon sink enhancement. These methods are intended to promote the green transformation of urbanization in rural and township areas, advance ecological civilization, and facilitate low-carbon development. The results provide insights for micro-scale planning and development in stock regions within territorial spatial planning, contributing to the practice and development of low-carbon rural development.
