天津沿海风暴潮灾害近20年统计及其成因分析

摘要

根据塘沽海洋环境监测站从1991～2010年，20年的潮汐资料进行统计分析，分析得到天津平均每年发生近10年的100 cm以上的增水过程，天津沿海夏秋两季的最高潮位和平均潮位最高，且最大增水值多出现在夏秋两季，超过100 cm的增水天数多集中在春季和秋冬季，并从天文潮因素、气象因素、海平面上升、地面沉降，以及地理因素等，总结了天津沿海风暴潮灾害的成因，最后提出了相应的风暴潮灾害防范措施。%Based on tidal data statistical analysis for 20 years of Tanggu Marine Environmental Monitoring Station from 1991 to 2010, we concluded that an average of nearly 10 days of 100 cm above water increase took place at Tianjin coast every year. The maximum high tide and average tide of Tianjin coast occurred in summer and autumn, and the maximum water increase also occurred in summer and autumn. Days with water increase more than 100 cm mostly occurred in spring, autumn and winter. Then we summarized the causes of coastal storm surge disaster in Tianjin based on astronomical tide factors, meteorological factors, sea level rise, land subsidence, and geographic factors, et al. Final y, we proposed storm surge disaster prevention measures.
