摘    要:由于海岸带的地理条件和海洋动力特性的复杂性以及人类开发活动对海岸带的影响,近岸海域的生态环境系统在空间分布上有很大的变异性.基于现场实测资料,建立系统的空间变异分析模型,对海岸带生态环境空间变化规律进行分析,可以充分了解不同区域的污染特征和变化趋势.应用所构建的空间变异分析模型对渤海湾天津近岸海域的水环境特性进行分析,结合对应年份的入海流量及其变化,分析了天津渤海湾海岸带污染的主因子和区域水环境的分布特征,结果可以对海洋功能区的划分和水环境综合评价结果进行验证和补充.

关 键 词:渤海湾    生态环境特性    空间变异分析    主因子分析    主要污染物

Abstract:The eco-environment systems of coastal areas are of great variability in a spatial distribution because of the inequalities among developing activities in seashore,as well as the complexities and instability of geographical and hydrodynamic conditions within these areas.On the basis of the field measured water quality data,a spatial variation analysis model is established.This model can be used to analyze the spatial variation of the eco-environment in a coastal area,then the characteristics and trend of the pollution in different areas can be obtained.By using the spatial variation analysis model, the characteristics of the water environment of the Bohai Gulf near the Tianjin coast and the main pollutant factors are analyzed.After that,according to the distribution characteristics of the water environment,the division of oceanic functional area and general assessment of aquatic environment can be demonstrated and modified.
Keywords:Bohai Gulf  characteristics of eco-environment systems  spatial variation analysis  main factors analysis  main pollution
