With the rapid development of economy and society,the lack of land for urban development has become the core restricting factor of urban scale development in the process of urban development.Based on this,it will also lead to a series of problems,such as traffic congestion,deterioration of environmental resources and so on.Therefore,in the development and utilization of urban land resources,we should strive to achieve the transfer from the ground to the underground.The research and development of new "land resources" will help to expand the urban capacity,strengthen the urban function reasonably,and promote the change of urban environment,so as to ensure the achievement of the goal of urban sustainable development.Therefore,in the process of urban planning,the government must strengthen the development of underground space.Salt cavern underground space is a special kind of underground space,which is difficult to use and has many restrictions,but it is a very effective way to expand the urban capacity.Huai’an salt mine,as one of the most large salt mines in China,has high reserves,long mining time and many powerful mining enterprises.It has unique advantages in the development and utilization of underground space of salt caverns.Therefore,how to promote the development and utilization of underground space of salt caverns efficiently and quickly,It is of great theoretical and practical value to study how the government can realize its own value and discuss its function in the process of underground space utilization and management of Yanxue in Huai’an City.Based on the theory of new public management and the theory of land space right,combined with the research on the utilization and management of underground space of salt caverns in Huai’an City,this paper introduces the methods of literature analysis,investigation and comparative research to obtain the relevant data This paper studies and analyzes the role of the government in the utilization and management of salt cavern underground space in Huai’an City from five aspects: systematic planning,construction of management mechanism,construction investment and technical specifications of salt cavern underground space.The results show that the reasons for the problems in the utilization and management of salt cavern underground space in Huai’an City mainly include: unclear ownership scope of salt cavern underground space,lack of management rules system,unsmooth management system and lack of systematic planning and arrangement.In view of this,the author puts forward the "issue of clear relevant regulations on ownership";To issue relevant management measures and technical specifications;Establish and improve the management system and mechanism;To formulate special plans and incorporate them into the overall land and space planning;The paper puts forward five countermeasures and suggestions on the relevant fund policy to further optimize the role of government in the utilization and management of underground space in salt caverns. |
