Abstract: Since the reform and opening up, the Pearl River Delta region has formed a large number of 'semi-urbanized areas', accumulating a significant amount of fragmented and historical legacy land. With the advent of the era of stock planning, land consolidation has emerged as a vital lever for revitalizing stock land, promoting intensive and economical land use, and optimizing the allocation of incremental resources. However, in practical land consolidation work, challenges such as difficulty in contiguous consolidation, mismatch between land supply and demand, and disconnected planning systems persist, further constraining the redevelopment and systematic development of existing and new land. Guided by the modernization of national spatial governance capacity and level, this article introduces the concept of spatial governance to innovate and explore comprehensive land preparation planning methods. Thoughts are proposed on expanding the spatial scope of governance objects, enhancing the value of governance goals, promoting negotiation and co-governance among stakeholders, and refining governance approaches. Taking C District in Guangzhou City, Guangdong Province as an example, this study sorts out the comprehensive land preparation planning methods under the transformation of spatial governance through digital empowerment, clarifying goal-oriented implementation, and institutional innovation.
