【摘要】 地下空间是一种重要的资源。本文通过对比研究地下空间开发数据,将中国城市地下空间发展水平进行了分级,并分析不同等级下社会经济的特点,然后分别从不同角度对地下空间指标与人口密度、地均GDP、人均汽车保有量等指标进行了相关性分析。结果表明,不同城市的地下空间开发强度与其地均GDP、人口密度具有高度的线性相关性。以上海市为例研究发现,同一城市不同时期的地下空间开发强度与人口、GDP、汽车保有量等指标可能存在多元线性关系。研究结果一方面验证了地下空间开发对社会经济发展的依赖性,即较高的地均GDP是所须具备的外部条件,较高的人口密度则是内在驱动力。另一方面也表明某些社会经济指标对地下空间发展阶段具有重要的指示作用。更多还原

【Abstract】 Urban underground space( UUS) is a kind of important space resource. Based on collecting data on UUS developed area and urban economic and social factors,the levels of UUS development in different Chinese cities have been classified. Then the corresponding urban socio-economic characteristics under different levels of UUS development have been compared and analyzed. Afterwards,the correlations between UUS data and socio-economic data,which include permanent population density,GDP per km2 and vehicles possessive quantity per capita,have been respectively analyzed from the horizontal and vertical aspects. The results have shown that there is a highly linear correlation between UUS development intensity and GDP per km2,as well as population density. Furthermore,it has been found that there could be multivariate linear relationship among UUS development intensity,population density,GDP per km2 and vehicles possessive quantity per capita of a certain city( e.g. Shanghai) in different periods of urban development. The results indicate that UUS development is highly depended on urban socio-economic level,that is,high GDP per km2 is an essential external condition while high population density is internal driving force. Also,results indicate that some socio-economic indexes maybe have important indicator function on UUS development stage.更多还原
