Abstract

Globalization presents significant challenges to the authenticity of world heritage sites, often leading to tensions between preservation and development. Southwestern mountainous cities in China, despite relatively slow economic growth, have managed to maintain well-preserved historical and cultural heritage, though these areas remain underrecognized internationally. This study examines the spatial connectivity and vitality of public spaces in Guiyang, a representative city. Using Voronoi polygons and complex network analysis, the investigation focuses on the distribution, connectivity, and vitality optimization of public spaces in historical districts. Results indicate that natural factors shape the spatial organization, with social public spaces demonstrating the highest network stability. In contrast, collective spaces show local stability but are vulnerable to socioeconomic disparities. Both types exhibit a core-periphery structure with varying levels of openness. The proposed Distribution-Network-Vitality-Path (DNVP) system provides a framework for enhancing public space vitality, offering practical guidance for heritage conservation and urban planning globally.

西南历史街区公共空间网络连通性与活力优化体系构建——以贵阳为例

全球化对世界遗产的真实性提出了重大挑战，往往导致保护与发展之间的紧张关系。中国西南山区的城市，尽管经济增长相对缓慢，但仍保留了保存完好的历史文化遗产，尽管这些地区在国际上仍未得到充分认识。本研究考察了代表性城市贵阳公共空间的空间连通性和活力。利用Voronoi多边形和复杂网络分析，研究重点是历史街区公共空间的分布、连通性和活力优化。结果表明，自然因素塑造了空间组织，社会公共空间表现出最高的网络稳定性。相比之下，集体空间表现出局部稳定性，但容易受到社会经济差异的影响。这两种类型都表现出开放程度不同的核心-外围结构。提出的分布-网络-活力-路径（DNVP）系统为增强公共空间活力提供了框架，为全球遗产保护和城市规划提供了实践指导。

期刊介绍： in Shams Engineering Journal is an international journal devoted to publication of peer reviewed original high-quality research papers and review papers in both traditional topics and those of emerging science and technology. Areas of both theoretical and fundamental interest as well as those concerning industrial applications, emerging instrumental techniques and those which have some practical application to an aspect of human endeavor, such as the preservation of the environment, health, waste disposal are welcome. The overall focus is on original and rigorous scientific research results which have generic significance. Ain Shams Engineering Journal focuses upon aspects of mechanical engineering, electrical engineering, civil engineering, chemical engineering, petroleum engineering, environmental engineering, architectural and urban planning engineering. Papers in which knowledge from other disciplines is integrated with engineering are especially welcome like nanotechnology, material sciences, and computational methods as well as applied basic sciences: engineering mathematics, physics and chemistry.
