Study On Development And Utilization Of Underground Space And Optimization Of Function In Urbanized Regions

Along with the rapid development of urbanization and the agglomeration of urban population of our country in recent years, to lead to more and more urban problems, such as the city ground space is crowded, the traffic congestion is severe, the environmental pollution is increasingly serious,the urban public space and human space is insufficient, etc. these phenomena is especially serious at the populated areas in the city. To seek a way to save resources and protect the environment is the key that we solve the urban problems. Under the sustainable development to expand the size of capacity and improve the efficiency of in city this way. Underground space as a new natural resources is being developed and used by human, and its unique advantages is popular with more and more people. Many practice shows that the development and utilization of urban underground space not only can effectively relieve various conflicts that led by the shortage of land resources in cities, but also it is one of the important ways to realize the urban sustainable development.Since the reform and development, the development and utilization of underground space have being gradually growed up in the cities in our country. However, in China,as a result of the development and utilization of underground space started relatively late, and the construction, planning and management of experience was poor, that causes the function of the existing underground space is imperfect in our country. Mainly displays that the ground and underground is not fully integrated, the underground environmental comfort and the safety performance of disaster prevention is poor. In the face of the current situation of the commercial space of the city ground resources are scarce and the advent of the era of dungeons that the architect and urban workers problem that the optimization of the underground space function, improve environmental comfort and safety of underground space, awaken their potential commercial value,become not ignore. With the capacity of urban economic development rapidly increasing of China, we must to accelerate the comprehensive development of urban underground space and research of function optimization, to eliminate or relieve the strain on city ground space and to improve the environment of floor space provides a strong support. This paper focus on how better to develop and use the urban underground space, specifically we should to optimize the function of the high density urban development areas and environment of this space, thus establishing the efficient, compact, three-dimensional urban space optimization system in the research.First, this paper around the development present situation and ways of the urban underground space in the high density area, this part will clarify the foreign advanced and the insufficiency of domestic in underground space development through to review the domestic and foreign urban space development and theory and practice of high density area. In order to optimize the function of the underground space for further research we should summed up in a timely manner to carry out the high density area renewal and reconstruction for old city through typical case study, the empirical theory development and practical experience.Secondly, this part we will take the underground space development in Henan province stadium project as an example, to study the function optimization and the scale coordination between up and down of sports ground in city populated area. We should combine the indoor and outdoor space, underground space and on the ground into a whole of stadium, we also should reasonably plan the traffic flow and effectively solve the entertainment space and environmental degradation and the problem of parking difficulty surrounding the project. Then do it coordinate with each other, complement each other, among the surrounding buildings, traffic network, the ecological environment.Again, for the high quality of the modern urban underground space in safety and environmental, the project of Henan province stadium is used to study the underground space development and the surrounding environment condition, underground environment quality standards and underground space comfort, security and other issues. According to the environment quality request of underground space we research how to improve the hot and humid, ventilation of the underground space and aseptic environment, and through the introduction of green vegetation and water, how to strengthen the underground environment ecological, humanized, interesting, security, as well as, and how to optimize the disaster prevention and mitigation system of underground space. Then we can realize the comfortable and safe environment of underground space.Finally, this part summarized the full text and puts forward improving the planning system and optimization Suggestions our current country urban underground space. Including the planning of urban underground space, management and legal rules for underground space development strategy are discussed. This article’s results will have inspiration for modern city function optimization of creative, it also has the certain reference value by summarizing and presenting the integrated strategy in the reality of urban construction practice.
