基于UNA分析的陈大滘既有城市工业区空间与设施改造策略研究

在产业结构升级与转型的大背景下，许多既有城市工业区普遍存在空间利用混乱、设施配套不足等问题。运用城市网络分析法，选取Reach、Straightness、冗余指标、寻找客流量与客流中间性五种量化指标，对顺德陈大滘既有城市工业区进行综合研究，分析存在的问题。从配套设施、慢行系统、公共空间三个方面，提出优化选址及调整规模的配套设施改造策略；整体保留与局部修补相结合，构建立体慢行网络系统，协同提升慢行网络密度与设施数量的慢行系统改造策略；构建自然与人工结合的生态步行廊道，结合路权改造与设施完善优化沿街空间，塑造多层级特色生态景观节点的公共空间改造策略。

Research on the Space and Facility Transformation Strategies of Chen Dajiao Urban Industrial Area Based on UNA Analysis

In the context of industrial structure upgrading and transformation, disordered space utilization and an insufficient number of facilities represent universal problems in many industrial areas. In the current study, the case of the Chen Dajiao urban industrial area was examined. Its problems were comprehensively analyzed using an urban network analysis method based on the five quantitative indicators of reach, straightness, redundancy index, find patronage and patronage betweeness. A strategy of site-selection optimization and facility-scale adjustment from the perspectives of supporting facilities and improving the slow-traffic system and public space was developed. Furthermore, a strategy for a prototypical slow-traffic network system was developed by combining overall reserve and local remediation to collectively improve the density of the slow-traffic network and number of facilities in the area. Moreover, an ecological corridor combining nature and artificial landscapes was built to optimize street space by combining the reconstruction of right-of-way and facility perfection and creating public spaces with multi-level characteristic ecological landscape nodes.
