气候变化和人类活动对天津海岸带影响综述

Review on the Impacts of Climate Changes and Human Activities on the Costal Zone of Tianjin

21世纪全球海平面上升和区域地面沉降叠加所致的相对海平面上升速率存在加快趋势,将加剧天津沿海地区风暴潮、洪涝灾害和土地淹没的危害,影响沿海地区的城市抗灾功能、建筑物安全及生态资源。为此,本文综合讨论了气候变化导致的海平面上升和地面沉降对天津沿海风暴潮、海岸侵蚀以及港口码头的影响。建议滨海新区建设要高度重视海洋灾害的监测预警,提高沿海地区防潮和防汛工程的设计标准和城市抗灾能力,以有效实现滨海新区经济和社会可持续发展。

The rate of relative sea-level rise caused by global sea-level rise and regional land subsidence in the 21st century has been accelerating.That will increase the risk of storm surge,flood and land submergence in the coastal area of Tianjin,and influence city anti-disaster ability,building safety and ecological resources.Therefore,the impacts of sea-level rise and land subsidence caused by climate change on storm surge,coastal erosion and port terminals in the coastal areas of Tianjin are discussed.Based on the significant influences,it is suggested that government should pay high attention to the monitoring and early warning of marine disasters,increase the design standard of tide and flood prevention projects and city anti-disaster ability in the process of constructing the New Coastal Region,to achieve the sustainable development of economy and society in New Coastal Region of Tianjin.
