基于多源数据的滨水空间活力时空分异特征与影响机制研究--以沈阳浑河核心段滨水空间为例

Influence Mechanism and Spatio-temporal Differentiation Characteristics of Waterfront Vitality Based on Multi-source Data:A Case Study of the Core Section of Hunhe Waterfront in Shenyang

该文以沈阳浑河核心段滨水空间为研究对象,以活力时空特征为切入点,借助多源数据分析方法,通过活力强度与活力波动指数两项指标探索滨水空间活力的时空变化规律,并结合典型时期之间的指标变化情况,归纳出两组具有活力属性差异的四个单元类型。该文通过关联性分析,进一步提炼出针对全域单元的13项活力强度显著影响因子与11项活力波动指数显著影响因子,并深入探究四个类型单元各自独特的活力特征与活力显著影响因子,进而从共性与异性两方面阐释滨水空间活力影响机制,同时围绕活力发展需求,提出适宜的更新切入点。旨在为人本需求导向的滨水空间规划建设提供理论支撑,为人性化滨水空间更新提供有力依据。

Taking the core section of Hunhe Waterfront in Shenyang as the object,and taking the spatio-temporal characteristics of vitality as the breakthrough point,we explore the spatial and temporal variation law of waterfront vitality through vitality intensity and vitality fluctuation index with the help of multi-source data,and sum up four unit types in two groups with different vitality attribute in combination with the changes of indicators during the typical period.Then we further extract 13 significant impact factors of vitality intensity and 11 significant impact factors of vitality fluctuation index for all units through correlation analysis.And we deeply explore the unique vitality characteristics and significant impact factors of vitality for four types units,and explain the influence mechanism of waterfront vitality from both commonness and difference,then we put forward appropriate breakthrough point of waterfront regeneration according to vitality development needs.We hope to provide theoretical support for planning and construction of waterfront based on human demand orientation,and to provide valid basis for humanized waterfront regeneration.
