基于价值维度的北京历史街道活力评价

Evaluation of the Vitality of Beijing's Historic Streets based on Value Dimensions

历史街道是城市遗产环境的重要组成部分,反映城市特色的同时,也承载着城市的核心价值。目前对于历史街道活力评价的研究,多是以空间和时间的维度进行。然而,价值也是使历史街道保持活力的重要因素。本研究以北京市的9条(3种类型:文化类、商业类和居住类)历史街道为例,运用层次分析法,构建价值维度的历史街道活力评价框架。评价指标为:历史价值(包含历史环境、文化环境和空间环境)、使用价值(包含交流环境、商业环境和居住环境)、可持续价值(包含教育环境、活力环境和创新环境)。结果表明,东交民巷、南锣鼓巷、樱桃斜街在3种街道类型中具有最高的活力,文化类的街道比商业类和居住类的街道具有更高的活力。

Historical streets are an important component of urban heritage environment,reflecting urban characteristics while also carrying the core values of the city.At present,research on the vitality evaluation of historical streets is mostly conducted from the dimensions of space and time.However,value is also an important factor in maintaining the vitality of historical streets.This study takes 9 historical streets(3 types:cultural,commercial,and residential)in Beijing as examples,and uses Analytic Hierarchy Process to construct a value dimension vitality evaluation framework for historical streets.The evaluation indicators are:historical value(including historical environment,cultural environment,and spatial environment),usage value(including communication environment,commercial environment,and residential environment),and sustainable value(including education environment,vitality environment,and innovation environment).The results show that Dongjiaominxiang,Nanluoguxiang and Yingtaoxiejie have the highest vitality among the three street types,and cultural streets have higher vitality than commercial and residential streets.
