Suitability Evaluation Of Urban Underground Space Development Based On

With the social and economic development, urbanization, faster and faster, more and more population, resulting in contradictory needs and limited urban land between the city’s capacity to expand increasingly prominent, seriously affected the stable development of the city, to ease this contradiction is the best way to expand the city below the surface of space. Urban Underground Space Development has become the main urban development perspective, the world’s attention. Urban Underground Space Development enormous capacity and potential, but are vulnerable to the impact of many geological conditions, economic strength and social benefits, and has a certain irreversibility, this objective requires the development of urban underground space full argument before the necessity and feasibility. At present, the urban underground space development in a relatively blind phase, and presented a waste of resources, chaotic state. Therefore, the Urban Underground Space Development Suitability worthy of further exploration. Scientific Assessment of Urban Underground Space Development suitability level to help determine a reasonable scale and development capabilities, to provide basis for decision making in urban planning, so as to promote the rational and orderly development of urban underground space.Based on GIS theory, location theory, land systems theory, and theory of sustainable land use, theory and case analysis, qualitative and quantitative analysis and geographic information system comprehensive evaluation of these three methods systematic study experimental area-underground space development status and influencing factors of the main city of Kunming, and then to build a suitability evaluation index system as a starting point to build comprehensive evaluation model for urban underground space suitability expand the instance analysis, according to the final test the results, learn from existing successful experiences of urban underground space development, put forward reasonable developing countermeasures of urban underground space.
