摘要
论文基于驱动力-压力-状态-影响-响应(DPSIR)模型,构建湛江湾海岸带生态系统健康评价指标体系。运用层次分析法(AHP)和熵权法结合确定指标权重,对2010-2018年湛江湾海岸带生态系统健康状况进行评价与分析。结果表明:2010、2013、2015、2018年,湛江湾生态健康等级分别为临界健康(Ⅲ)、较健康(Ⅱ)、临界健康(Ⅲ)、较不健康(Ⅳ)。影响湛江湾海岸带生态系统健康的主要因素为环境保护与治理资金投入、滨海旅游总人次、海洋生产总值、台风风暴潮灾害次数、海洋灾害损失。
Based on the driving force-pressure-state-impact-response(DPSIR) conceptual model, a multi-indices evaluation system was constructed to investigate ecosystem health of Zhanjiang Bay coastal zone on this paper.AHP and Entropy weight method were used to determine the index weight, and the evaluation and analysis of Zhanjiang Bay coastal zone ecosystem health status from 2010 to 2018 were carried out. Results showed that the ecological health levels of Zhanjiang Bay in 2010, 2013, 2015 and 2018 were critical health(Ⅲ), relatively healthy(Ⅱ), critical health(Ⅲ) and less healthy(Ⅳ). The main factors that affect the ecosystem health of Zhanjiang Bay coastal zone are the investment of environmental protection and control funds, the total number of coastal tourism, the gross marine product, the number of typhoon storm surge disasters and the loss of marine disasters.
