城市管理案件量化分析是城市管理水平提升的技术支撑。针对城市管理典型案件(街面秩序、市容环境及宣传广告),该文提出了一种热点探测流程和方法,并分析城市管理案件全局分布模式。针对传统量化研究的权重确定未考虑研究对象空间分布的问题,该文提出了基于城管案件近邻指数的权重确定方法,并以此为基础开展城管案件的全局分布模式研究。实验结果表明:3种典型城市管理案件呈显著的聚集分布,并且热点区域符合实验区的实证考察;近邻指数作为权重指标具有客观性、计算高效性,合理反映了城管案件的空间分布。
The quantitative analysis of urban management cases is the technical support for the improvement of urban management level. Aiming at the typical cases of urban management (street order, city environment and advertising), this paper presents a hot spot detection process and method, and analyzes the global distribution pattern of urban management cases. In order to solve the problem that the weight of traditional quantitative research does not consider the spatial distribution of the research object, this paper proposes a method to determine the weight of neighborhood index based on urban management case, and studies the global distribution model of urban management case based on it. The experimental results show that the three kinds of typical urban management cases are obviously aggregated and distributed, and the hot spots are in conformity with the empirical study. The index of neighbors is objectivity as a weight indicator and the efficiency is calculated, which reasonably reflects the spatial distribution of urban management cases.
