摘要
推动农业用水效率、农业经济发展与农业生态环境协同发展是实现黄河流域农业高质量发展的必然选择。基于2005-2020年沿黄9省区数据,构建黄河流域农业用水效率—农业经济发展—农业生态环境(WEE)综合发展评价指标体系,运用耦合协调度模型及障碍度模型探析三者耦合协调发展特征及障碍机制。结果表明:(1)农业用水效率、农业经济发展与农业生态环境子系统在2005-2020年呈不同程度波动上升趋势;(2)黄河流域WEE复合系统处于高耦合状态,协调度由勉强协调向初级协调迈进并呈“西高东低”的空间格局,且农业生态环境滞后型省区最多,农业用水效率滞后型省区最少;(3)各子系统对应的主要障碍因子对农业用水效率子系统阻滞程度最强,而对农业经济发展子系统阻滞程度最弱。推动传统农业向现代化农业转型升级,打破省区壁垒促进农业资源要素自由流动,因地制宜制定相关政策等是加强黄河流域及各省区农业用水效率、农业经济发展与农业生态环境优质协同发展的重要举措。
Promoting the synergistic development of agricultural water use efficiency,agricultural economic development and agricultural ecological environment is an inevitable choice to realize the high-quality development of agriculture in the Yellow River Basin.Based on the provincial panel data of 9 provinces(and regions)along the Yellow River Basin from 2005 to 2020,a comprehensive development evaluation index system of agricultural water use efficiency—agricultural economic development—agricultural ecological environment(WEE)was established in this paper.Additionally,the coupling coordination model was adopted to measure the coupling coordination development level of the WEE composite system,and the obstacle degree model was further applied to identify the obstacle factors.The results showed that:①The agricultural water use efficiency,agricultural economic development and agricultural ecological environment subsystems showed upward trends with different degrees of fluctuation from 2005 to 2020.②The WEE composite system in the Yellow River Basin was in a highly coupled state,with the degree of coordination progressing from barely coordination to primary coordination and showing a spatial pattern of“high in the west and low in the east”.Moreover,the provinces(and regions)with lagging agricultural ecological environment were the most and the provinces(and regions)with lagging agricultural water use efficiency were the least.③The main obstacle factors corresponding to each subsystem were the strongest in blocking the agricultural water use efficiency subsystem while the weakest in blocking the agricultural economic development subsystem.Boosting the transformation and upgrading of traditional agriculture to modernized agriculture,breaking down provincial and regional barriers to promote the free flow of agricultural resource elements,and formulating relevant policies in accordance with local conditions are crucial measures to strengthen the synergistic development of agricultural water use efficiency,agricul
