PPGIS與傳統民眾參與方式在社區議題討論與居民參與程度上之比較研究：以宜蘭縣龜山島社區為例

Following the substantial raising of modern democracy consciousness in the last two decades, people's participation in public affairs has become the mainstream of community development, especially by widely using Public Participation Geographic Information Systems (PPGIS). However, due to barriers of PPGIS technique and high cost of computer hardware deployment, so many communities in Taiwan could not get good efforts by applying this tool. In order to compare the real benefits of PPGIS-based approach and traditional public participation approaches and to clearly identify the appropriate real-time platform in different stage of participatory planning process, this study introduced four different approaches: (1) direct oral participation ; (2) handy-drawing participation (without maps); (3) handy-drawing participation (with reference maps); (4) PPGIS platform with photographs into community planning issues of Gueshan Island Community in Yilan County. The results showed that individual interviews and group discussions will lead to completely different conclusions because of the complex human factors. Different approaches were also suitable to encourage maximum public participation during different phases of the planning process. In the very beginning stage, traditional approaches (e.g., direct oral interview and handy-drawing interview) are suitable to present the most realistic viewpoints of residents. Otherwise, PPGIS platform with active maps, interactive visualization, vector layers and photos will bring more imagination and greater depth of discussion. However, due to different participant's adaptability of four approaches, this study recommended that communities should keep flexibility when choosing approaches for discussion. Besides, integrating the results on PPGIS platform would be a better way to negotiate with government and specialist.
