摘　　要：目的为提升历史文化街区街道空间品质。方法以沈阳市工人村历史文化街区为研究对象,分析历史街区空间现状,利用相关性分析探讨绿视率与其他空间测度的影响关系以及对历史文化街区街道空间品质的耦合影响,建立历史文化街区空间品质的多元回归模型,探究空间品质与空间测度特征的影响机制。结果在历史文化街区中绿视率、历史建筑可见度、围合度、景观多样性为高值显著特征,天空开阔度、参与度为低显著特征且空间差异明显;历史文化街区的空间品质主要受到绿视率、天空开阔度、历史建筑可见度、围合度的影响;绿视率与空间品质成正相关关系,与其他空间测度成负相关关系。结论以历史文化街区空间测度特征量化研究为导向,根据空间测度结果提出历史文化街区街道空间的设计导则,为制定控制项奠定基础。In the revitalization of historical and cultural districts,vegetation plays a crucial role in enhancing street quality.The balancing of green visual experiences with other spatial metrics is a significant focus for improving the quality of Workers′Village historical and cultural streets in Shenyang.This study analyzes the current spatial status of the historical district,employing correlation analysis to explore the relationship between green view ratio and other spatial metrics,as well as their combined impact on street space quality.A multiple regression model is established to investigate the mechanism through which spatial quality is influenced by spatial metric characteristics in historical and cultural street areas.The research findings indicate:High values of green view ratio,visibility of historical buildings,enclosure,and landscape diversity are significant features in historical and cultural districts,while openness of sky and participation exhibit low significance and notable spatial differences.The spatial quality of historical and cultural districts is primarily influenced by green view ratio,openness of sky,visibility of historical buildings,and enclosure.Green view ratio shows a positive correlation with spatial quality but a negative correlation with other spatial metrics.This study is guided by a quantitative analysis of spatial metric features in historical and cultural street areas,proposing design guidelines for street spaces based on these metrics,thereby laying the groundwork for regulatory frameworks.
