基于DPSIR模型的韶关市生态安全评价

Ecological Security Evaluation of Shaoguan City Based on the DPSIR Model

城市生态安全评价可以为生态文明建设和生态环境管理决策提供参考.基于DPSIR(驱动力-压力-状态-影响-响应)模型构建韶关市生态安全评价指标体系,利用熵权法和层次分析法对指标赋权,评价了韶关市2014—2021年的生态安全状况.结果表明:韶关市生态安全水平总体上呈现上升趋势,生态安全级别由Ⅰ级上升为Ⅳ级;驱动力指数和压力指数逐年上升,而状态指数、影响指数和响应指数虽呈上升趋势,但部分年份有下降.建议韶关市今后应注重提高污染防治能力,加强生态空间保护,加大节能环保和科学技术投入,推动经济社会发展与生态环境保护的良性互动.

Urban ecological security evaluation can provide reference for ecological civilization construction and ecological environment management decisions.Based on the DPSIR(driving force-pressure-state-influenceresponse) model,an ecological security evaluation index system in Shaoguan city is constructed,using the entropy weight method and analytic hierarchy process.The method empowers indicators and evaluates the ecological security status of Shaoguan city from 2014 to 2021.The results show that the ecological security level of Shaoguan city generally shows an upward trend,and the ecological security level rises from Level I to Level IV;driving force index and pressure index has increased year by year,and although the status index,impact index and response index have shown an upward trend,they have declined in some years.It is recommended that Shaoguan city should focus on improving pollution prevention and control capabilities in the future,strengthen ecological space protection,increase investment in energy conservation,environmental protection and science and technology to promote the positive interaction between social development and ecological environmental protection.
