| 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. |
