    摘要:

    [目的] 对安徽省工业生态安全进行评价和预测,为安徽省工业生态安全可持续发展提供科学依据。[方法] 基于压力、状态、响应框架和生态、环境、经济、社会框架构建工业生态安全评价指标体系,采用聚类工具进行安全等级划分,结合熵权法和综合指数法评价2009—2018年安徽省工业生态安全水平,运用BP神经网络模型对2019—2025年工业生态安全水平进行科学预测。[结果] ①从总体上看,2009—2018年安徽省工业生态安全评价指数呈波动上升趋势,安全等级由“临界安全”上升为“较安全”;②从各子系统来看,2009—2018年压力子系统的评价指数呈上升态势,状态和响应子系统的评价指数呈先下降后上升态势;③BP神经网络预测结果显示:2019—2025年安徽省工业生态安全态势总体呈波动上升状态,处于“临界安全”向“较安全”转变态势;④影响安徽省工业生态安全的主要障碍因素包括第二产业从业人员比例、第二产业占GDP的比例、污水集中处理率、森林覆盖率和人口密度,是今后调控的方向。[结论] 研究期间安徽省工业生态安全波动明显,但总体上呈上升趋势,工业生态安全得到明显的改善。

    Abstract:

    [Objective] The industrial ecological safety of Anhui Province was evaluated and predicted, in order to provide a scientific basis for the sustainable development of industrial ecological safety in Anhui Province. [Methods] Pressure, state, response framework and ecological, environmental, economic, and social framework were used to establish the industrial ecological safety evaluation index system. Clustering tools were used to classify safety levels, and combined the entropy weight method and the comprehensive index method to evaluate the industrial ecological safety level in Anhui Province from 2009 to 2018. A BP neural network model was employed to scientifically predict the industrial ecological safety level in Anhui Province from 2019 to 2025. [Results] ① From an overall perspective, the industrial ecological safety evaluation index of Anhui Province from 2009 to 2018 showed a fluctuating upward trend, and the safety level rose from “critical safety” to “safer”. ② From the perspective of each subsystem, the evaluation index of the pressure subsystem showed an upward trend from 2009 to 2018, and the evaluation indexes of the state and response subsystems first declined and then increased. ③ The overall situation of industrial ecological state in Anhui Province from 2019 to 2025 fluctuated and rose, and the safety level rose from “critical safety” to “safer”. ④ The main obstacles affecting the industrial ecological safety of Anhui Province included the ratio of employees in the secondary industry, the ratio of the secondary industry to GDP, and the ratio of centralized sewage treatment, forest coverage, and population density, which providing direction for future regulation. [Conclusion] The industrial ecological state in Anhui Province fluctuated noticeably during the study period, but showed an overall upward trend, and the industrial ecological state was significantly improved.
