The research aims to redefine how adaptive planning approach can help traditional spatial planning system to deal with conservation and development land use conflicts through a set of adaptation plans. As most planning system in the world, spatial planning in Taiwan in concerned with both planning making and the control of development (Chen & Shih 2010). Hence, the Northeast Coastal National Scenic Area (NCNSA) Plan is the master plan of the traditional comprehensive model dominating land use and regional planning since 1976. In addition, the designation of slope land in Gongliao (the dominating administrative area of NCNSA) by Rules of Slope-land Conservation and Utilization Act regulated and restricted the built area development. The NCNSA master plan combined with zoning plan reflects the ESAs guidance in regional level and strictly protects landscape from development. As a result, the contradiction areas are mainly overlapped with the settlements in floodplain and mountain villages along Shuangxi River valley. However, the rigidness of land use regulations not only eliminates the possibilities for specific type waterfront development along Shuangxi River valley, but also leads to conflict relationship between the designated conservation areas and the locals. Three research questions will be answered in this study: (1) What are the conservation and development conflicts in case study area? (2) What are the priority spatial development principles? (3) What are the strategies to integrate conservation and development land use conflicts? The research methods include official document review and landscape analysis. A set of adaptation plan will be used to illustrate as development strategy between nature conservation and development. The conclusion will help the completeness of existing local development plan response to national and regional policies as well as local needs.
