多维视角下的城市滨水空间开放性研究——以上海滨江核心区为例

Analyzing Urban Waterfront Spatial Openness Characteristic From Multi-Dimensional Perspective:A Case Study of Shanghai Waterfront Central District

增强城市滨水空间的开放性特征是提升城市活力的重要支撑,也是进一步促进城市滨水空间高质量发展的重要内容。区域路网结构、公共交通系统以及城市用地功能与一系列社会经济活动紧密相关,能够从使用规模、使用效率、使用行为等不同角度反映滨水空间的开放性特征,是影响城市滨水空间活力的重要因素。建立由路网系统整合度、轨道交通覆盖度、城市功能混合度3项指标组成的多维测度体系,对上海滨江核心区开展实证比较研究。结果显示,不同分区的单项、综合性指数差异明显,表明上海滨江核心区内的空间开放性水平存在较大差距。基于计算结果,对上海滨江核心区的空间开放性影响因素做了分析解读并提出了相应建议。

Shaping spatial openness characteristic for urban waterfront is not only a major support to enhance the vitality of the city,but also a critical content to promote the high-quality development of urban waterfront district.Road network structure,public transport system and land use functions are closely related to a series of social and economic activities,which have significance for affecting the vitality of urban waterfront space from different angles such as the scale,the efficiency,and the behavior of space use.This paper sets up a multi-dimensional measurement system including three indicators:road network integration degree,rail transit coverage degree and urban mixed function degree,and launch the case study of Shanghai waterfront central district.The results show that,there was a marked difference in the single and synthetic indexes of each section,which means in Shanghai waterfront central district,the spatial openness characteristic have big differences.Based on the results,the paper also analyses the influence factors for shaping the spatial openness characteristic in Shanghai waterfront central district and puts forward corresponding suggestions.
