摘要:
城乡融合、地上与地下空间协同探测、评价、规划是节约集约利用空间与自然资源,增强城市韧性,促进人与自然和谐共生现代化建设的重要途径。针对中国新型城镇化与乡村振兴协同发展面临着“多规合一”的国土空间规划、地上与地下空间协调集约利用等新的重大科技问题,以关中平原城市群为研究对象,基于地球系统科学和地球关键带理论,汲取系统论、协同论、信息论等理论,提出了城乡融合、地上与地下空间协同探测、综合评价、统筹规划的新时期城市地质理论,以及城市强干扰环境下地下空间精细化探测和建模关键技术、基于地下水位控制的地上与地下空间风险防控技术、“取热不取水”的地下空间地热能绿色开发新技术,并在多个城市得到成功应用。
Abstract:The collaborative detection and evaluation planning of ground and underground space is an important way to enhance the comprehensive carrying capacity of the city and promote the high–quality development of the city. In view of the new major scientific and technological problems such as "multi–plan integration" territorial spatial planning, coordinated and intensive utilization of ground and underground space aimed at the coordinated development of new urbanization and rural revitalization in China, taking Guanzhong plain urban agglomeration as the research area, based on the theories of the earth system science, the earth key belt, system, synergy and information, this paper puts forward the urban geological theory in the new period of urban–rural integration, coordinated detection, comprehensive evaluation and overall planning of ground and underground space; breaks through the key technologies of fine detection and modeling of underground space under the strong urban interference environment; proposes the risk prevention and control technology of ground and underground space based on groundwater; reveal the heat conduction law of geothermal fluid–exchanger in underground space, and raise the new green development technology of geothermal energy in underground space of "taking heat but not taking water". Which will provide the technique support for the urban planning, construction and operation management, land space planning, natural resource management, etc. And the theroies and the technologies have been successfully applied in many cities.
