摘　　要：海洋经济已成为天津市国民经济中重要的组成部分,随着不断发展,为满足海洋综合管理、海洋资源的合理利用、海洋污染综合治理等方面提出的更高要求,需要充分了解海域水体环境的现有状况。利用2006—2007年渤海湾(天津近岸)4个航次的水文气象调查资料和2006年夏季4个定点连续观测站的海流调查资料,重点分析了天津近岸海域温度盐度的分布状况及变化规律,并对天津市海岸带和海涂资源综合调查(海流部分)的历史资料进行了验证。通过分析表明,渤海湾夏季环流整体趋势未发生较大变化,但余流很小;与历史资料相比较,流速有减小趋势,而且流速普遍较弱;海水温度和盐度的垂直变化不大。The marine economy has become an important part of the national economy in Tianjin.In order to meet the higher requirements by the comprehensive marine management,rational use of marine resources,marine pollution and other aspects of comprehensive management,it＇s necessary to fully understand the existing marine environment conditions.Using hydro-meteorological investigations in the Bohai Bay during four cruises in 2006 and 2007（Tianjin Coast） and four fixed currents continuous observation station investigation data in summer 2006,the temperature and salinity distribution of Tianjin coastal waters is analyzed.The historical data during Tianjin coastal zone and wetland resources investigation（current portion） has been verified.The analysis shows that the overall trend of summer circulation in the Bohai Bay has not changed greatly,but the residual current is very small;the flow rate has decreased and stays weakly compared to historical data;water temperature and salinity vertical changes lightly.
