    摘要:

    [目的] 研究甘肃省泾河流域农村生态环境质量评价的相关问题,为农村生态环境保护和高质量发展研究提供参考。[方法] 基于压力—状态—响应(PSR)模型,构建了甘肃省泾河流域农村生态环境质量评价指标体系。运用熵值法和综合指数法对生态环境质量水平进行评价,并采用灰色GM (1,1)模型进行预测。[结果] 2010—2019年农村生态环境质量综合指数等级变化趋势为“劣等—差等—中等”,但总体呈现上升趋势,压力指数呈“Ⅴ”型波动变化,状态指数和响应指数逐年增长,说明环境治理的政策实施有效,预计到2021年将达到良好等级。[结论] 今后还需加大农村环保的资金和政策投入,改善各地环保制度措施,增强民众意识等。

    Abstract:

    [Objective] Issues related to rural eco-environmental quality assessment in the Jinghe River basin of Gansu Province were studied in order to provide references for rural eco-environmental protection and high-quality development research.[Methods] Based on the pressure-state-response (PSR) model, a rural eco-environmental quality evaluation index system for the Jinghe River basin in Gansu Province was constructed. The eco-environmental quality level was evaluated using the entropy method and the comprehensive index method. The model was predicted by using gray GM (1,1).[Results] The grade change trend of the comprehensive index of rural eco-environmental quality from 2010 to 2019 was "bad-poor-medium", but the overall trend was increasing. The pressure index exhibited a V-shaped change pattern, and the state index and response index increased year by year, indicating that the implementation of environmental governance policies were effective. The index was expected to reach a good level by 2021.[Conclusion] In the future, it is necessary to increase investment in rural environmental protection funds and policies in order to improve local environmental protection systems and measures, and to enhance public awareness.
