胶州湾海岸带环境脆弱性分析

本文以胶州湾为研究区，在对导致海岸带脆弱性的各种压力进行定量化分析的基础上，构建具有针对性的海岸带环境脆弱性评估模型，对胶州湾环境脆弱性进行有效判别。研究发现，由人为排放污染物导致的海洋环境质量下降，是致使胶州湾生态系统脆弱性的直接原因。虽然作为压力因素的气候变化和城市化指标对脆弱性指数的直接贡献率不大，但是作为导致海岸带环境脆弱性的根本因素，随着气候变化趋势的不断显现和人类对海岸带开发利用程度的不断加剧，海岸带脆弱性不断增加的趋势是必然的。因此应该在控制直接影响环境的排污行为的基础上，有效控制对海岸带生态和环境产生影响的各种压力，以从根本上避免海岸带生态和环境脆弱性不断加剧。

Analysis on environmental vulnerability of the coastal zone in Jiaozhou bay

In this study, we took Jiaozhou bay as the study area to build an assessment model, which was used to effectively distinguish the environmental vulnerability of Jiaozhou bay. The mode was based on the quantified a variety of pressures. It was found that anthropogenic emissions of pollutants are the direct factors induced environmental vulnerability in Jiaozhou bay. Climate change and urbanization are the fundamental factors that results in the vulnerability of coastal ecosystem. It is inevitable that the deteriorating environmental ecosystem get along with climate changing and human exploitation. In order to avoid the deterioration in the environmental vulnerability of the coastal zone, it is necessary to control sewage discharge and all the other factors that contribute to coastal ecosystem directly and indirectly.
