Abstract: the China Spatial Planning Observation Network (CSPON) aims to address the demands for integrated, all-factor, and dynamic governance of territorial space in the new era. It promotes local governments' implementation of planning system reforms from top to bottom. Focusing on Guangzhou as a pilot city, the paper proposes solutions and practical explorations for developing municipal CSPON. Firstly, for vertical integration, CSPON should seek to strengthen alignment with the provincial planning system, enhance information feedback mechanisms, and establish a multi-level development unit planning transmission system within the city. Secondly, for horizontal collaboration, CSPON should develop effective data governance systems and standards, improve the multi-stakeholder collaborative system, and refine implementation pathways. Thirdly, for perception and governance technologies, CSPON should advance technology systems, such as "space-air-ground" physical perception and "human-affair-object" social perception, while building intelligent governance capacities for dynamic integration of multi-source heterogeneous data. Fourthly, for smart governance, CSPON should create a model that aligns with operational and business requirements. Reflecting on Guangzhou's experience, the study reflects on problems such as the need for high-quality data, significant financial resources, and exploratory orientation. It concludes with strategic suggestions to integrate and optimize systems, enhance capacity in data governance, and prioritize practical application of governance models.
