厦门湾海岸带区域人类开发活动的生态效应评价

Ecological Effect Assessment of Coastal Development in Xiamen Bay,China

生态效应评价可揭示海岸带人类活动对生态系统已产生的效应(包括累积性效应)以及对变化趋势进行回顾总结,为沿海地区的资源和环境管理提供服务。文章通过统计分析历史数据进行生态效应评价,得出厦门湾生态系统属于亚健康水平,生态安全处于一般脆弱(预警状态)状态,存在一定的风险;同时讨论了生态效应和人类开发活动之间的关系。

The ecological effect,including the accumulative effect and the trend of change caused by human activities in coastal areas,could be revealed by retrospective ecological assessment. The results will be very helpful for the resource and environmental management in coastal areas. Based on the statistical analysis of historical data,the results of ecological assessment show that the ecosystem in Xiamen Bay is in a sub-health level and the ecological safety level is at the medium vulnerable state （warning state）. The relationships between ecological effects and human activities were also discussed.
