青岛市海岸带生态系统压力综合评价指标体系研究

Study on comprehensive evaluation index system of coastal ecological stress in Qingdao

通过分析海岸带生态系统主要胁迫因素并结合青岛市承压现状建立了青岛市海岸带生态系统压力评价指标体系,并应用于定量评价青岛市海岸带生态系统承压状况。评价结果表明,1990～2005年青岛市海岸带生态系统压力呈波动变化,整体呈上升趋势,与20世纪90年代相比,填海压力明显增大、海洋排污压力呈现迅速增长态势,经济发展自2003年起已由增大压力项变为减弱压力项。

Through analyzing the main stress factors and status of ecological system in the coastal zone of Qingdao, the Index System of Comprehensive Evaluation of Ecological Pressure in the coastal zone was constructed and the Ecological Stress Index （ESI） in the coastal zone of Qingdao from 1990 to 2005 was calculated. The results showed that the ecological stress in the coastal zone of Qingdao shows obvious fluctuation and ascending trend from 1990 to 2005. Compared with data of last century, the stress from the marine reclamation increase and marine waste discharged showed the increasing trend rapidly. The economic growth becomes a weakening stress factor from enlarged stress factor since 2003.
