文化产业成长对城市空间形态演变的影响——以西安市核心区为例

基于扩展强度指数、等扇分析法、核密度分析及空间句法等方法,运用1998年、2008年、2018年3个时期的文化产业企业地理数据、夜间灯光数据及城市道路网轴线模型分析西安市核心区文化产业空间成长与城市空间形态演变的特征,探究二者空间关系与作用机制。结果表明：① 西安市核心区文化产业沿“东北-西南”走向扩展,其空间集聚格局逐渐由“单核”“一带两核”向“一轴一带两核”演变。② 核心区城市外部空间形态沿“东北-西南”走向扩展,内部空间形态由“团状单核”“条带状主次双核”向“团带状双核”演变。③ 核心区文化产业成长与城市空间形态演变呈显著的关联性,即不同时期二者空间扩展方向基本一致,空间形态格局演变高度耦合。④ 核心区文化产业先导型发展模式推动城市外部空间形态的扩展,而填充型发展模式,包括在城市建成区的空间扩展与向既有产业集聚区的持续集聚推动着城市内部空间形态的优化。研究对完善文化产业空间研究体系,提升产业空间支撑城市空间转型的协同度方面具有重要意义。

The influence of spatial growth of cultural industry on the evolution of urban spatial morphology:Taking the core region of Xi'an as a case study

Based on methods of extended intensity index, equal sector analysis method, kernel density analysis and spatial syntax, with the assistance of enterprise geographic data of the cultural industries, as well as the nighttime light data and the axis model of the urban road network in the years of 1998, 2008 and 2018, we analyzed the characteristics of spatial growth of cultural industries in Xi’an’s core districts and the evolution of urban spatial morphology, and explored their spatial relationship and the corresponding mechanism. The results show that:(1)The cultural industries in Xi’an’s core districts expanded along northeast to southwest, gradually evolving from single core or one belt and two cores into one axis, one belt and two cores in terms of spatial agglomeration pattern.(2) The urban external spatial morphology of the core districts expanded along northeast to southwest, and the internal spatial morphology evolves from lump-shaped single core or strip-shaped primary-secondary cores to lump and strip shaped double cores.(3) There is a significant correlation between the growth of the cultural industries in the core districts and the evolution of urban spatial morphology in different periods. That is to say, and the evolution of their spatial form patterns is highly coupled.(4) The pioneering development mode of the cultural industries in the core districts promotes the expansion of the urban external spatial form. The complementary development mode, including the spatial expansion in urban built-up area and continuously closing-up to the existing industrial agglomeration, facilitates the optimization of the urban internal spatial morphology.The study is of great significance for perfecting the spatial research system of cultural industry and promoting the coordination in which industrial space supports urban spatial transformation.
