基于PPGIS公众参与的南京锁金村社区微更新研究

探索社区微更新背景下社区公众参与的新方法与思路，结合实践确定研究区微更新重点内容及措施。以南京锁金村社区为例，搭建公众参与地理信息系统（Public Participation GIS, PPGIS）平台理论框架。借助户外助手、谷歌地球软件调研，得到空间节点的地理信息；通过PPGIS平台呈现对应信息并实现与公众的信息互动，得到微更新的重点内容；基于微更新策略，完成针对性改造实践。PPGIS平台是社区微更新的技术创新，可高效搜集公众参与需求，便于采取针对性实践措施。

Public Participation Research Based on PPGIS in Nanjing Suojincun Community Micro-regeneration

To explore new approaches and ideas for public participation in community under the background of urban renewal, then determine the key parts and measures of community micro-regeneration by practice. Take Nanjing Suojincun community as an example, and put forward a new theoretical framework of PPGIS to combine Outdoor Assistant APP, Google Earth engine with a visual platform based on the network terminal, then took specific measures for community micro- regeneration. It finished collecting the basic geographic information of Suojincun community with the help of Outdoor Assistant APP and Google Earth engine. Then, it identified the most important nodes in the micro- regeneration with the development of internet technique applied in the PPGIS by setting up an information exchanging platform. Finally, it achieved the targeted renewal practice with the help of updated strategy. The PPGIS platform has been an innovative technology in community micro- regeneration, and it collected public participation information in a highly effective way which was useful to take targeted measures.
