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.
