摘要:

水资源-能源-粮食-生态(WEFE)系统的协同发展已成为区域可持续发展的关键议题,尤其在干旱半干旱区,系统协调性对资源安全与生态安全至关重要。基于2006—2022年中国30个省(自治区、直辖市)(除西藏自治区和港澳台地区以外)的面板数据,在省域尺度上构建了WEFE系统综合评价指标体系,采用熵权法、耦合协调度模型、空间自相关分析与灰色关联度模型等方法,系统刻画了中国WEFE系统协调发展的时空演变特征与空间关联格局,并重点剖析了干旱半干旱区在省域层面上的差异化表现及其主导约束机制。结果表明:(1) 在省域层面,中国WEFE系统综合发展水平稳步提升,但子系统发展不均衡,水资源子系统长期滞后,在干旱半干旱区表现出显著的刚性约束特征。(2) 中国WEFE系统耦合协调度整体由濒临失调衰退类向勉强协调发展类演进,空间上呈现东部领先、中部稳健、西部追赶的梯度格局,区域差距逐步缩小。干旱半干旱区实现了从全国低值集聚区向局部高值增长极的转变。(3) 从空间关联看,中国WEFE系统耦合协调度具有稳定的空间正相关性,高-高集聚与低-低集聚并存。(4) 从约束机制看,全国层面,粮食安全是支撑WEFE系统协调发展的基础。具体到子系统的制约因素,干旱半干旱区主要受用水效率和能源利用效率的制约,而湿润半湿润区则更多受生产效率和生态质量的限制。

Abstract:

Synergistic development of the water-energy-food-ecosystem (WEFE) system is a critical issue in regional sustainable development, particularly in arid and semi-arid regions where systemic coordination is essential for resource and ecological security. Based on panel data from 30 Chinese provinces (autonomous regions and municipalities), excluding Xizang, Hong Kong, Macao, and Taiwan, from 2006 to 2022, a comprehensive provincial scale evaluation index system for the WEFE system was constructed. Methods entropy weight, coupling coordination, spatial autocorrelation, and grey relation were employed to systematically characterize and analyze the spatiotemporal evolution and spatial association patterns of WEFE system coordination in China, particularly the differential performance and dominant constraint mechanisms of arid and semi-arid regions at the provincial scale. We found that: (1) At the provincial scale, the overall development level of the WEFE system in China showed steady improvement, though with uneven subsystem development. The water resources subsystem consistently lagged, exhibiting a pronounced rigid constraint in arid and semi-arid regions. (2) The overall coupling coordination of the WEFE system evolved from near-disorder/recession to barely coordinated development. Spatially, it exhibited a gradient pattern in which the east led, the center was stable, and the west was catching up, though with regional disparities gradually narrowing. Arid and semi-arid regions transitioned from national clusters of low coordination to local growth poles with high coordination values. (3) Coupling coordination demonstrated stable positive spatial autocorrelation, with the coexistence of high-high and low-low agglomeration patterns. (4) Regarding constraint mechanisms, at the national level, food security formed the foundational support for WEFE system coordination. Specifically regarding subsystem constraints, arid and semi-arid regions were primarily constrained by water use and energy utilization efficiency, whereas humid and semihumid regions were more limited by production efficiency and ecological quality.
