天津沿海海平面上升影响风险等级研究

Risk Level Study on the Impact of Sea Level Rise Along the Coast of Tianjin

海平面长时间的累积上升将加剧风暴潮、土壤盐渍化和海岸侵蚀等灾害。沿海各地区的自然特征与社会经济发展水平差异明显,而各地区由于海平面上升引起的自然环境的影响和社会经济的风险也呈现地域差异。文章对天津滨海新区海平面上升影响风险进行分析,评估海平面上升对天津沿海各海洋功能区社会经济发展产生的风险,经评估发现天津滨海新区南部海平面上升风险等级最高,北部风险等级最低。

Long-term cumulative rise of sea level will exacerbate disasters such as storm surges,soil salinization and coastal erosion.However,there are obvious regional differences in the natural characteristics and socio-economic development levels of the coast.The impact of the natural environment and the socio-economic risks caused by sea level rise has shown regional differences.The paper analyzed the risk of sea level rise impact in Tianjin Binhai New Area.It was assessed that the southern part of Tianjin Binhai New Area would have the highest level of sea level rise risk and the northern part would have the lowest level of risk.
