    摘要:

    [目的] 探查黄河流域与长江经济带农业水资源利用效率与影响因素间的差异性特征,为有效提升两地农业用水效率与农业可持续发展决策提供科学依据。[方法] 基于2009—2019年黄河流域与长江经济带19省市的面板数据,利用超效率SBM模型,并结合Malmquist指数、核密度估计、标准差椭圆、Tobit回归等方法对其差异性进行分析。[结果] ①农业水资源利用效率均呈整体上升趋势,黄河流域各年效率值波动幅度较大,内部差异明显,其效率重心于山西省与陕西省边界摆动;而长江经济带各年起伏较缓,其效率重心呈现向西南部迁移趋势,年均效率值略高于黄河流域。②技术进步均是引起农业水资源利用效率变动的主要原因,2009—2019年黄河流域技术进步指数略高于长江经济带。③影响两地农业用水效率增长的因素差异较大,其原因与其所处的自然地理环境与经济发展水平有较大联系。[结论] 黄河流域与长江经济带农业水资源利用效率整体良好,但区域差异性较大。因此,要因地制宜采取针对性措施,并从科技投入、政府引导与农民参与等多个维度推动两地农业用水效率的提升与持续优化,实现流域农业的可持续发展。

    Abstract:

    [Objective] The differences of agricultural water use efficiency and its influencing factors between the Yellow River basin and the Yangtze River Economic Belt were studied in order to provide a scientific basis and reference for decision-making to effectively improve agricultural water use efficiency and sustainable agricultural development in the two regions.[Methods] Based on data from 19 provinces and cities in the Yellow River basin and the Yangtze River Economic Belt from 2009 to 2019, differences in agricultural water use efficiency and its influencing factors were analyzed by use of the super-efficiency SBM model, the Malmquist index, kernel density estimation, standard deviation ellipse, Tobit regression and other methods.[Results] ① Agricultural water use efficiency increased over time. The annual efficiency value for the Yellow River basin fluctuated greatly and internal differences were obvious. The efficiency center oscillated at the border between Shanxi Province and Shaanxi Province. However, the annual efficiency value for the Yangtze River Economic Belt fluctuated slowly, and its efficiency center moved to the southwest over time, and the annual average efficiency value was slightly higher than the efficiency value observed for the Yellow River basin. ② Technological progress was the main reason for the change in agricultural water use efficiency. The technological progress index for the Yellow River basin was slightly higher than the index of the Yangtze River Economic Belt from 2009 to 2019. ③ There was a great difference in the factors influencing the increase in agricultural water use efficiency over time between the two regions, and the reasons for the difference are closely related to the natural geographical environment and economic development.[Conclusion] Agricultural water use efficiency in the Yellow River basin and the Yangtze River Economic belt is generally good, but there are great regional differences. Therefore, targeted measures should be taken according to local conditions, and the efficiency of agricultural water use in the two regions should be promoted and continuously optimized from the perspectives of scientific and technological input, government guidance, and farmers' participation so as to produce sustainable development of river basin agriculture.
