“…The spatial matching of food supply, carbon sequestration, and water production services is mainly distributed in the Hexi Oasis region because of the abundant agricultural resources, high human population density, and large demand for water and food in the oasis. When studying the matching relationship between supply and demand of ESs from the perspective of water-energy-grain in the Yellow River Basin, some scholars also proposed that the high-high spatial matching zone of ESs is mainly distributed in the downstream area with high population density, which is consistent with the results of this study [22]. The high-high spatial matching zone of windbreak and sand xation is scattered, mainly in-uenced by the variability of land cover.…”

“…This study used a four-quadrant model to explore the supply and demand patterns of each ESs. First, the supply and demand of ESs were standardized using the Z-score method [22]. Then, using the standardized supply as the X-axis and demand as the Y-axis, a two-dimensional coordinate system was constructed, and four matching modes were obtained and visualized, including high-high spatial matching, low-low spatial matching, low-high spatial misalignment and high-low spatial misalignment [45].…”

“…This spatial state is consistent with the spatial pattern of natural conditions in the Hexi region. In addition, as urbanization and human activity intensify, water use in agriculture and industrial production gradually rises, creating a con ict between the supply and demand for water resources [22]. The supply-demand ratio of windbreak and sand xation has been in a state of under supply for a long time., With the passage of time, this undersupply state has gradually weakened.…”

To achieve the best management of the ecosystem and sustainable socioeconomic development, it is crucial to clarify the matching relationship between the supply and demand of ecosystem services (ESs). Therefore, four types of ESs were chosen for the Hexi region in this study: food supply, carbon sequestration, water yield, windbreak and sand fixation. This study evaluated the supply-demand and matching relationships between various ecosystem services tapping into the InVEST model, the supply-demand ratio of ecosystem services, and the four-quadrant model. It also analyzed the supply-demand ratio of comprehensive ecosystem services and their cold and hot spots. The findings suggest that (1) the overall ESs supply showed an increasing trend, with a spatial pattern of “high in the southeast and low in the northwest”. The demand for food supply and carbon sequestration services has been increasing annually, while the demand for water production and wind and sand prevention services has been declining. The demand space is characterized by a layout similar to the distribution of population, production and living areas, and ecologically vulnerable areas; (2) From the perspective of quantity matching, with the exception of windbreak and sand fixation services which are in short supply, all others are in a state of oversupply. Regrading spatial matching, all ESs are primarily dominated by low-low spatial matching zones, with large areas concentrated in the northwest desert region; (3) The supply-demand ratio of overall ESs shows a fluctuating upward trend. The proportion of cold spots and sub-cold spots, which are mainly concentrated in the northwest region, accounts for more than 50%, while that of hot spots and sub-hot spots is relatively small and mainly appears in the Qilian Mountains of the southern region and a few oasis areas.

“…Meanwhile, the WEF nexus idea offers a fresh angle from which to examine ESs (Hoff 2011;Costanza et al 2017), with relevant research focusing on the spatial identification of the matching of supply and demand as well as the sustainability of ESs based on the WEF nexus (Yin et al 2023;). However, current research has mostly concentrated on the ecosystem service function of WEF, and lack of research on its value, which is not conducive to integrate with socio-economic evaluation systems and economic management decisions.…”

Context The value of all the ultimate goods and services that the ecosystem provides for human welfare and long-term economic and social development is known as the gross ecosystem product (GEP). For the study of GEP accounting, the suggested water-energy-food (WEF) nexus offers a fresh viewpoint. Objectives The aim of this work is to build a GEP accounting index system based on WEF, investigate its spatiotemporal evolution characteristics, and assess trade-offs and synergies between and within water, energy, and food subsystems. Methods We used the Biophysical & monetary method to calculate the GEP amount based on WEF in five time periods (2005, 2009, 2013, 2017, 2021) and ArcGIS for spatial mapping. Functional quantity value of ecosystem services interactions were identified by statistically analyzing the spatiotemporal pattern. Results Considering the passage of time, the GEP based on WEF in the TGRA displayed an increase trend. From the standpoint of spatial evolution, the spatial distribution pattern of GEP based on WEF showed a spatial pattern of "high in the east and west, low in the middle". The GEP trade-offs based on WEF was dominating. It was discovered that the distribution space of cold and hot areas of a single ecosystem service function value in the three subsystems had spatial variances. Conclusions This study demonstrated that GEP based on WEF presents spatial heterogeneity, and the water subsystem contributed the highest proportion of ecosystem service value, and the tradeoffs/synergies of ecosystem service value were different at different times, as a whole and locally.

“…Herein, the upper reaches are the sources of the Yellow River with rich water resources; the middle reaches produce nearly 69.7% of coal in China; the lower reaches are an essential food production base. Moreover, driven by energy and food security strategies, water demand in the YRB will increase significantly, and the contradictions of supply-demand among the three resources will be further revealed (Yin et al, 2021;2023;Zhao et al, 2021).…”

For mankind’s survival and development, water, energy, and food (WEF) are essential material guarantees. In China, however, the spatial distribution of WEF is seriously unbalanced and mismatched. Here, a collaborative governance mechanism that aims at nexus security needs to be urgently established. In this paper, the Yellow River Basin in China with a representative WEF system, was selected as a case. Firstly, a comprehensive framework for WEF coupling coordination was constructed, and the relationship and mechanism between them were analyzed theoretically. Then, we investigated the spatiotemporal characteristics and driving mechanisms of the coupling coordination degree (CCD) with a composite evaluation method, coupling coordination degree model, spatial statistical analysis, and multiscale geographic weighted regression. Finally, policy implications were discussed to promote the coordinated development of the WEF system. The results showed that: 1) WEF subsystems showed a significant imbalance of spatial pattern and diversity in temporal changes; 2) the CCD for the WEF system varied little and remained at moderate coordination. Areas with moderate coordination have increased, while areas with superior coordination and mild disorder have decreased. In addition, the spatial clustering phenomenon of the CCD was significant and showed obvious characteristics of polarization; and 3) the action of each factor is self-differentiated and regionally variable. For different factors, GDP per capita was of particular importance, which contributed most to the regional development’s coupling coordination. For different regions, GDP per capita, average yearly precipitation, population density, and urbanization rate exhibited differences in geographical gradients in an east-west direction. The conclusion can provide references for regional resource allocation and sustainable development by enhancing WEF system utilization efficiency.
