摘要
在城市化步入增存转型的时代背景下,通过优化提升土地利用功能,盘活存量低效空间,对城市生态宜居建设、高质量可持续发展以及提升治理水平具有重要理论和实践意义。然而,当前有关城市存量低效空间的研究大多关注社会、经济、建成环境等维度,从功能角度精细化定量识别城市低效空间还有待深入研究。为此,论文从土地利用多功能视角出发,集成统计、调查、遥感、POI等多源数据,以及系统论、空间治理理论、GIS空间分析等理论和方法,诠释城市存量低效空间形成机理,建构城市存量低效空间精准识别方法及治理优化路径,并以西安市为例进行实证研究。研究发现:①西安市存量空间效能呈现“中间高—四周低”的空间分布特征,由城市中心向外围地区逐渐降低;②生产—生活短板功能为影响西安市建成区存量建设空间效能的主要障碍功能;③双重功能提升区包含的乡镇数量最多,三重功能提升区次之,单项功能提升区最少。城市总体层面的结构功能完善与提升是全面提升城市低效空间效能的首要任务;未来,西安市应坚持规划引领与分区优化原则,注重提升短板功能,全面优化城市存量低效空间,进而推动国土空间的合理开发与保护,实现高质量发展的目标。研究为西安市以及其他超特大城市存量低效空间优化提升提供理论、方法、实证参考。
In the context of urbanization transition from growth to stock retention,optimizing and enhancing land use functions to revitalize inefficient urban stock space is of significant theoretical and practical importance for urban ecological protection and livability improvement,high-quality sustainable development,and improving governance levels.However,current research on inefficient urban stock space mainly focuses on social,economic,and built environment dimensions,with few scholars addressing the issue of inefficient urban stock space from a functional perspective using detailed and quantitative research methods.Therefore,this study adopted a multifunctional land use perspective,integrating multi-source data such as statistics,surveys,remote sensing,and point-of-interest(POI),along with theories and methods from the systems theory,spatial governance theory,and GIS spatial analysis,to explain the formation mechanism of inefficient urban stock space.It also developed a precise identification method for urban inefficient stock space and governance optimization path,using Xi'an City as a case study for empirical research.The study found that:1)The spatial efficiency of urban stock space of Xi'an showed a"high in the center-low at the periphery"distribution,gradually decreasing from the city center to the outer areas.2)The production-living deficient function was the main obstructive function for one-third of the area in Xi'an City.3)The dual-function improvement zone contained the largest number of towns,followed by the triple-function improvement zone,and the single-function improvement zone had the smallest number of towns.Enhancing and optimizing the structural functions at the overall urban level is the primary task to comprehensively improve the efficiency of inefficient urban stock space.Moving forward,Xi'an should adhere to the principles of planning guidance and regional optimization,focus on improving deficient functions,and optimize the entire inefficient urban space to promote the healthy development and protection of territorial space,thereby achieving the goal of high-quality development.This study provides theoretical,methodological,and empirical references for optimizing inefficient urban stock space in Xi'an and other megacities.
