摘要:
前人对街道空间品质的研究多数针对较发达城市,已有的测度与评价体系不一定适用于拉萨这种少数民族地区的历史文化城市,且扎根于历史文化城市的街道空间品质测度与评价体系框架并不清晰。针对拉萨这类具有民族特色和雪域高原特点的国家历史文化名城,研究从步行体验角度,以舒适性、安全性、便捷性、人文性为研究维度,经互联网多源数据处理与测度,构建街道空间品质测度评价体系,对拉萨市林廓环路分别进行街道空间品质单因子评价与综合品质评价,进行各街道品质分级。结果表明:有近一半街道的空间品质评分偏低; 通过各个指标与街道空间品质测度值的相关性分析,发现主要问题是多数街道的民族色彩感知度、民族文化元素感知度、民族特色商业密度、服务设施便捷度较低,部分街道的路面可行度、遮阴率、立面连续性较低以及路面拥堵度较高,次要问题是大部分街道的商业业态丰富度与密度较低,部分街道的绿视率与天空可视率较低以及机动化程度较高; 为了优化拉萨街道空间品质与改善城市人居环境,提出优先优化策略与适当优化策略。本研究在街道空间品质研究领域中,在精度与广度上做了一定深化与拓展,加深了对民族地区历史文化城市街道空间品质的理解。
Abstract:
Previous studies on street space quality in a city are mostly aimed at developed cities. The existing measurement and evaluation system for exanimating street space quality in a developed city is not necessarily applicable to Lhasa City, a historical and cultural city in ethnic minority areas, China. Since it is not clear about the framework to inspection of street space quality in historical and cultural cities, it is quite necessary to explore it by a case study.From the perspective of walking experience, this research used multi-source data processing and measurement via Internet, and according to Maslows hierarchy of needs theory, it took comfort, safety, convenience, and humanity as research dimensions to build the measurement and evaluation system of street space quality. The following street space quality factors were accordingly introduced into model: green visibility rate, shading rate, sky visibility rate, facade continuity, road accessibility, traffic congestion, vehicle density index, diversity of commercial formats, density of commercial formats, convenience of service facilities, national color perception, perception of cultural elements and density of national culture commercial format.It performed the single factor evaluation and comprehensive quality evaluation of street space quality on nine streets of Linkuo Ring Road in Lhasa City on multiple dimensions basis, and completed quality grading of each street. The results showed that nearly half of the streets had lower spatial quality scores. Through the correlation analysis of each index with street spatial quality measurement, it was found that the main problem was that the cultural perception index and the convenience of service facilities were low in most streets, and the same the road accessibility, shading rate and facade continuity were low in some streets, but traffic congestion was high. The secondary problem was that the diversity and density of commercial formats in most streets were low, while the green visibility and the sky visibility at some streets were low but with high vehicle density index.The innovativeness of this paper lies in:(1)this research had carried out a specific study on the quantification indexes of culture dimension, which can be regarded as a pioneered exploration of the previous research gap;(2)Combining previous studies and regional circumstance, it explored the construction method of street space quality measurement and evaluation system in historical and cultural urban areas of ethnic minority areas, which was an extension of research angle;(3)The calculation method of some indexes and the crawling and application method of street view were improved, and the analysis was carried out by 360-degree panoramic street view, which was more comprehensive and accurate. Compared with the previous research on street space quality measurement and evaluation, this research had deepened and expanded research precision and breadth, and it enriched the understanding of street space quality in historical and cultural cities in ethnic areas;(4)The priority optimization strategy and appropriate optimization strategy were proposed, which provide supports for street space quality optimization and improvement of urban living environment in Lhasa and provide references in similar areas.
