基于场景理论的大城市旧城街道品质评价与提升研究——以成都市旧城典型街道为例

Research on the Quality Evaluation and Improvement of the Old Town Streets in Large Cities Based on Scene Theory:Taking Typical Streets in the Old Town of Chengdu as an Example

随着后工业化与存量规划时代的到来,大城市更加关注传统旧城区更新。街道是城市重要的公共空间,也是旧城多样化功能的主要载体。目前,我国大城市围绕旧城街道更新虽已取得一定成效,但许多街道更新仍面临难以满足居民多元场景及品质化需求的问题,街道场景品质有待进一步提升。文章基于场景营造视角,构建场景品质评价标准与体系,选取成都旧城三个典型街道作为研究案例,进行场景品质评价,对比、归纳不同价值导向下街道场景营造的手法与特征,为我国其他城市旧城街道更新实践提供一定的参考与借鉴。

With the advent of post-industrialization and stock planning era,big cities are paying more attention to the renewal of traditional old urban areas.Streets are important public spaces in cities and serves as the main carrier of diversified functions in old towns.At present,while there have been certain achievements in the renewal of old town streets in major Chinese cities,many street renewal projects still struggle to meet the diverse and high-quality needs of residents,indicating the need for further improvement in the quality of street scenes.This article is based on the perspective of"scene creation"to construct scene quality evaluation standards and systems.Three typical street cases in the old town of Chengdu are selected for scene quality evaluation,and the techniques and characteristics of scene creation for different value oriented streets are summarized and compared.This provides a certain reference for the renewal of old town streets in other cities in China.
