摘　　要：文章基于"压力-状态-响应"(PSR)模型构建海岛发展的指标评价体系,选取21个代表性指标评价该地区生态安全状况,对珠海市大万山岛的生态安全进行了分析研究。结果表明,2010—2017年珠海市大万山岛的生态安全指数总体呈上升趋势,2016年安全指数为0.679,达到生态安全Ⅱ级"较安全"等级。2010—2017年,压力指数从0.038升至0.162;由于废水、废气和固体废弃物排放增加,状态指数在2012—2016年呈现下滑趋势,从0.194降至0.074;响应指数明显上升,在2016年达到最高值0.496,而在2017年又下降至0.352。状态指数结果表明,经济增长与海岛生态环境承受能力之间的矛盾突出,大万山海岛资源的过度开发与生态环境的破坏导致各子系统协调度失稳下滑。An index evaluation system based on the"Pressure-State-Response"(PSR)framework with 21 representative indicators was constructed and used to evaluate the ecological security situation in the Dawanshan Island in Zhuhai in this study.The results showed that the ecological safety index of Dawanshan Island had been on the rise from 2010 to 2017.In 2016,the security index was 0.679,reaching the"relatively safe"level of ecological security II.The pressure index rose from 0.038 to 0.162 from 2010 to 2017.Due to the increase of wastewater,waste gas and solid waste emissions,the state index showed a downward trend from 2012 to 2016,during this period,the response index increased significantly,reaching the highest value of 0.496 in 2016 and dropped to 0.352 in 2017.The results of situation index showed that the contradiction between the economic development and the ecological environment and security was serious.The over utilization of resources and the ecological environment destruction in the Dawanshan Island resulted in the instability and decrease in the coordination degree of each sub-system.
