多情景模式下的新城地下空间开发策略研究——以成都天府国际空港新城为例

Research on Development Strategies of Underground Space of New City Area Based on Scenario Plan: A Case Study of Chengdu International Airport New City

城市新区的地下空间,作为地上空间的补充与活动空间优化的抓手,其实际开发情况受城市发展状况的影响,因此在确定地下空间规划的开发强度时,基于规划的动态性与可修订性,应考虑不同预期下的开发可能。依托GIS技术,利用情景规划的方式,对成都天府国际空港新城在不同发展水平下的地下空间的开发需求进行模拟,得出不同情境下的地下空间开发强度的变化,以期为新城的地下空间开发提供策略,同时为规划实施者应对不同情境下的开发及时提供灵活的应对措施和差异化的管控方式。

The underground space of the new city is a supplement of the ground and a gripper of the optimization of urban space,and its actual development situation is affected by the city development.Therefore,before development intensity of underground space planning is determined,the possibility of development in different expectations should be considered based on the dynamism and modifiability of the planning.Based on GIS technology,using scenario plan,this paper simulates development demand of underground space of Chengdu International Airport City in different levels to acquire the change of the development intensity of underground space in different scenarios,aiming to provide strategies for developing underground space of new city area,and also provide the flexible measures&various management for planning implementer to deal with development problems in different situations.
