Abstract:

With the large-scale development of urban renewal across the country, the spatial perception and participation degree of citizens in the promotion of the project has become a topic of increasing concern in the academic circle. Meanwhile, public participation is also a way of community governance. Under the influence of humanism, community-scale urban renewal research is devoted to exploring the perception and participation of different resident groups in the process of renewal. Takeing Guanggang New Town during the implementation stage of the renewal project as the case, analyzes the current situation of green space construction, and tries to explore the public participation in green space construction of Guanggang New Town through the remote sensing of green space change and in-depth interview. The study found that :(1) the increase of green space area and spatial accessibility in the area of Guanggang New Town were significantly improved, but there was no positive correlation with the green space perception of new residents;(2) with the construction of the renewal project, new residents enter the built-up area, while the renewal planning stage is mainly carried out according to the opinions of the original subjects, and the degree of public participation of different subjects is uneven, resulting in the disorder of spatial fairness.(3) the change of the subject is a dynamic factor that should be paid attention to in the process of urban renewal. Spatial perception of different subjects needs to be paid attention to in the process of community governance. This study combines remote sensing and geographic information system technology, and takes the perception of low efficiency as the topic to discuss community governance, in order to provide some references for the public participation and collaboration paradigm in the stage of practicing of urban renewal projects.

Key words: urban renewal, community governance, spatial perception, green space benefits, Guanggang New Town

摘要：

随着城市更新的开展，市民在项目推进中的空间感知及参与程度日渐成为学者和城市管理实践者关注的话题。在此背景下，本研究以更新项目实施阶段的广州市荔湾区的广钢新城为案例，通过遥感影像提取的绿地变化强度并结合深度访谈，试图探索广钢新城绿地建设的公众参与状况。研究发现：（1）广钢新城的绿地面积增加，空间可达性明显提升，然而与新进入居民的绿地空间感知没有呈现正相关联系；（2）随着更新项目的建设与空间主体的流变，建成区出现新的主体进入，而更新规划阶段主要以原有主体的意见开展，新旧主体公众参与程度参差不齐，从而造成空间使用的失序；（3）主体的变化是城市更新过程中应关注的动态要素，不同主体空间感知需要在社区治理过程中获得关注。本研究结合遥感及地理信息系统技术，以绿地效益的感知作为切入点探讨社区治理，以期为城市更新建设阶段的公众参与及协作范式提供一定的参考。
