摘要:

基于20112022年汾河流域40个县(市、区)的农业、水资源、经济、社会等面板数据,利用耦合协调度、Dagum基尼系数分解法及核密度估计等方法系统分析流域农业水资源利用效率与农业现代化耦合协调度的时空演变特征及其驱动因素,以期为汾河流域实现农业高质量发展提供可行性思路。结果表明:(120112022年汾河流域农业水资源利用效率呈波动上升趋势,效率评价得分均值2011年的0.094显著提升至2022年的0.134(P<0.05)。2011−2022年汾河流域的农业水资源利用效率基本呈中游(0.117)>上游(0.096)>下游(0.087)的空间分布。(220112022年汾河流域农业现代化发展水平呈波动上升趋势,发展水平评价得分均值由2011年的0.183显著(P<0.05)提升至2022年的0.256空间分布上表现为中游(0.220)和下游(0.225)农业现代化发展水平显著高于上游(0.168)。320112022年汾河流域农业水资源利用效率与农业现代化耦合协调度呈波动上升趋势,年均增长率为1.7%。空间分布上表现为中游耦合协调度(0.392)显著高于上游(0.349)和下游(0.370)。(4)汾河流域上、中、下游耦合协调度区域差异主要来源于区域内差异和区域间差异,上游因山地地形和基础设施薄弱,内部资源分配不均,中游得益于集约化生产模式和政策支持,表现为均衡发展,下游在生态治理和技术进步方面取得显著成效。(520112022年汾河流域耦合协调度核密度曲线呈右移趋势,峰值逐渐升高且带宽收窄,表明上、中、下游域间差异逐步缩小,整体协同性增强。研究建议加强汾河流域上游基础设施建设,推动中游技术扩散,优化下游生态治理政策,以促进区域间均衡发展。

Abstract:

Based on panel data encompassing agriculture, water resources, economy, and society from 40 counties (districts, cities) in the Fenhe river basin from 2011 to 2022, this study employed the coupling coordination degree model, Dagum Gini coefficient decomposition, and kernel density estimation to systematically analyze the spatiotemporal evolution characteristics and driving factors of the coupling coordination degree between agricultural water resources utilization efficiency and agricultural modernization. The aim was to provide scientific evidence and policy recommendations for achieving high−quality agricultural development in the Fenhe river basin. The results showed that: (1) from 2011 to 2022, the agricultural water resources utilization efficiency in the Fenhe river basin showed a fluctuating upward trend, with the mean efficiency evaluation score significantly increasing from 0.094 in 2011 to 0.134 in 2022 (P<0.05). Spatially, the efficiency generally followed the pattern of midstream (0.117) > upstream (0.096) > downstream (0.087). (2) The level of agricultural modernization in the Fenhe river basin also exhibited a fluctuating upward trend during the study period, with the mean evaluation score for development level significantly rising (P<0.05) from 0.183 in 2011 to 0.256 in 2022. Spatially, the midstream (0.220) and downstream (0.225) regions were significantly higher than the upstream region (0.168). (3) The coupling coordination degree between agricultural water resources utilization efficiency and agricultural modernization in the Fenhe river basin demonstrated a fluctuating upward trend from 2011 to 2022, with an average annual growth rate of 1.7%. Spatially, the midstream region (0.392) exhibited significantly higher coordination levels than the upstream (0.349) and downstream regions (0.370). (4) The regional disparities in coupling coordination across the upstream, midstream and downstream regions of the Fenhe river basin mainly stemmed from intra−regional and inter−regional differences. Upstream regions suffered from uneven resource allocation due to mountainous terrain and weak infrastructure, while the midstream regions benefited from intensive production models and policy support, demonstrating balanced development. Downstream regions achieved notable progress in ecological management and technological advancement. (5) During the study period, the kernel density curve of the coupling coordination degree in the Fenhe river basin shifted rightward, with peaks gradually rising and bandwidth narrowing, indicating a gradual reduction in disparities among the upstream, midstream and downstream regions and enhanced overall coordination. The study recommends strengthening infrastructure construction in upstream regions, promoting technology diffusion in midstream regions, and optimizing ecological governance policies in downstream regions to foster balanced regional development.
