构建了计划经济时期和转轨期中国城市资本密度空间分布的理论模型,并与市场经济体制的同类模型了对比研究,以兰州市为例,利用高精度卫星影像和大规模实地调查方法获取数据,采用GIS和数理统计方法,利用容积率指标,分区、分行业进行了实证研究。结果表明:市场经济体制、计划经济体制和转轨期中国城市资本密度由中心到外围的空间变化规律并不相同,而后者居于前两者之间,存在向市场经济空间模型靠近的趋势;计划经济体制、转轨期的中国城市土地利用由中心到外围为商务→住宅→工业→农业模式;转轨期容积率比计划经济时期均有不同程度提高,住宅、商务等建筑容积率的空间分布模型更接近市场经济体制下的模型;住宅、商务、工业等建筑容积率依次递减在一定程度上解释了住宅、商务用地的向心分布和工业用地外迁的现象。
The theoretical model of the spatial distribution of urban capital density in China during the planned economy and the transitional period is established and compared with the similar models of the market economy system. Taking Lanzhou as an example, high-precision satellite images and large-scale field surveys are used to obtain the data. Using GIS and mathematical statistics, using the volume index, zoning, sub-sectors conducted an empirical study. The results show that the spatial variation of market capitalization in the market economy system, planned economy system and urban capital density in China during the transition period are not the same from the center to the periphery, while the latter live in the first two, and there is a tendency to approach the market economy spatial model; Institutional, and transitional period, the urban land use in China’s cities from the center to the periphery is in the form of business → housing → industry → agriculture. The volume ratio during the transitional period has been raised to varying extents as compared with that in the planned economy period. The spatial distribution models of building floor area ratios such as residential buildings and commercial buildings are closer The model of market economy system; Decreasing building volume ratio of housing, commerce and industry in turn explains to a certain extent the centripetal distribution of residential and commercial land and the phenomenon of industrial land relocation.
