In the new era,the scientific and rational development and utilization of underground space is an important path to promote the enhancement of urban connotation and practice the transformation of green development.In the context of the transformation of the national spatial planning system,underground spatial planning should actively respond to and adapt to new policy requirements and practical needs,further clarify the planning system,improve the planning content,and break through key technical methods.It should strengthen the transmission of development planning to spatial planning,build an underground spatial planning system of"vertical'1+3'and horizontal'1+N'",and use planning research and deepening design as beneficial supplements to the planning system.Each level of underground spatial planning should fulfill its responsibilities and highlight key points,forming the framework and main content of underground spatial planning from the perspective of the entire city/county region,with a focus on the central urban area and key districts.This paper will closely investigate the two key links of front-end resource evaluation and back-end planning implementation,explore two technical methods of comprehensive evaluation of underground spatial resources and planning implementation transmission,and scientifically guide the rational development and utilization of underground space resources.
