沿海城市地面沉降挑战与应对
Challenges and responses to land subsidence in coastal cities:a case study of Shanghai
摘要
Abstract
Land subsidence poses a critical geological-environmental threat to coastal city sustainability,characterized by complex genesis,extensive spatial distribution,and persistent progression.Focusing on Shanghai—a representative low-lying coastal megacity—this study addresses the land subsidence risks driven by the coupling of intensive anthropogenic activities(predominant groundwater extraction)and vulnerable geological settings.Through systematic analysis of global subsidence mitigation strategies and six decades of Shanghai's monitoring and comprehensive governance practices,we propose the innovative"Shanghai Model".This framework incorporates:① A multi-element collaborative prevention system;②Groundwater zoning and stratified control mechanism;and ③ A full-chain legal safeguard framework.This trinity system—integrating"technological upgrading-management refinement-legal constraints"—has reduced the annual subsidence rate from a historical peak of 105 mm to less than 6 mm.The model provides a systematic solution for global coastal cities confronting compound subsidence risks under evolving anthropogenic pressures.关键词
