综合治理视角下的海岸建筑退缩线划定与管控研究OA

The coastal building setback line is an important tool for addressing coastal disaster risks,ensuring ecological security,and implementing spatial governance.Distinct from single-objective-oriented engineering defense or ecological protection approaches,the integrated governance perspective emphasizes an integrated spatial governance pathway characterized by multi-objective coordination,multi-sector collaboration,and a combination of stringent constraints with adaptive flexibility.Based on international governance trends,domestic institutional transformation requirements,and the practical conflicts between coastal zone protection and development,this paper takes Qingdao as a case study.It systematically analyzes the practical evolution and institutional characteristics of its coastal zone management,and further constructs a coastal building setback line control framework from the perspective of integrated governance,tailored to the actual needs of Qingdao.With the core objectives of safeguarding territorial security and ecological security,the study proposes a differentiated technical delineation approach comprising"basic delineation,classification-based correction,and evidence verification,"and establishes a management mechanism that combines stringent constraints with adaptive flexibility.The paper aims to provide a theoretical basis and practical references for the refined governance of coastal zones in China's coastal cities and regions.
