| 摘要: |
| 本研究以压力-状态-响应（PSR）模型为基础，在广西壮族自治区钦州湾构建钦州湾水环境绩效评估体系，测算2010-2017年该区域的环境绩效指数（EPI），并结合钦州市2010-2017年的生态环境建设与环保工作进展进行数据分析。研究结果表明，在2010-2012年，钦州市在污染减排方面取得明显成效，环境绩效明显向好；2013年后由于高强度的工业化建设与海洋开发活动给环境带来巨大压力，环境绩效指数在2013年达到47.42，为近几年最低。其后随着当地对环境问题的重视、环保投资力度的加大以及人们环保意识的日益增强，自2014年开始环境绩效指数出现较大幅度回升，后处于平缓状态，波动范围不大，环境质量有所提高。评估结果较好地反映了钦州湾附近海域的水环境变化趋势，为钦州湾的未来发展计划提供理论依据与数据支撑。 |

| Abstract: |
| Based on the pressure-state-response (PSR) model,the Qinzhou Bay water environment performance evaluation system in Qinzhou Bay,Guangxi Zhuang Autonomous Region was constructed.The environment performance index (EPI) of Qinzhou from 2010-2017 was calculated,the data were analyzed based on the progress of ecological environment construction and environmental protection in Qinzhou from 2010 to 2017.The results of the study showed that Qinzhou had achieved significant results in pollution reduction and its environmental performance had improved significantly in 2010-2012.After 2013,however,Qinzhou's environmental performance hit 47.42,which was the lowest in recent years due to the high-intensity industrial construction and marine development activities that had brought tremendous pressure to the environment.Later,with the increasing attention on environmental issues,investment in environmental protection and people's increasing awareness of environmental protection,the environmental performance index began to show a significant rebound,and then remained flat,with a small fluctuation range,and the environmental quality has improved since 2014.The evaluation result better reflects the changing trend of the water environment in the sea area near Qinzhou Bay,and provides theoretical basis and data support for the future development plan of Qinzhou Bay. |
