“…Delphin et al [43] found that climate change had a more significant impact on water supply and service supply than other driving factors in two watersheds in Florida, USA. Zhao et al [44] noted that population had the greatest impact on water supply service demand in Gansu province of China. We selected factors such as elevation, slope, soil layer thickness, rainfall, temperature, NDVI, land use type, population density, and GDP to evaluate the impact of these factors on the ratio of water supply and service demand.…”

The study of water service supply, demand, and flow in the Taihang Mountains in China can elucidate its supply and demand patterns, which are important for the sustainable utilization of water resources. We chose Gangnan Reservoir Basin in the Taihang Mountains as the research area. First, we evaluated the supply and demand of water supply services using the InVEST model and statistical methods. Then, ecosystem service flows were calculated based on river networks and altitude. Finally, the supply and demand pattern of water supply services based on ecosystem service flows was analyzed. The results showed the following. (1) The total supply and demand of water supply services in Gangnan Reservoir Basin were 8.18 × 108 m3 and 3.52 × 108 m3, respectively. (2) At the sub-basin scale, the minimum flow of both static and dynamic water supply services was the same, and the mean was significantly different. The maximum flow was also significantly different. Static water supply service flows were not significantly correlated with altitude, whereas dynamic water supply service flows were significantly correlated with altitude. (3) The demand area in the supply and demand pattern of water supply services based on dynamic ecosystem service flows was notably less than that based on static ecosystem service flows. The supply and demand patterns of water supply services defined the actual water shortage area, the area that pays for ecosystem services, and the areas of ecosystem service ecological compensation, providing a scientific basis for the safe and rational utilization of water resources in mountainous areas.

“…However, these studies have frequently ignored potential spatial correlations and complex interdependencies among multiple ESs. Therefore, the present study conducted a quantitative analysis to examine the relationship between ecosystem supply and demand and their evolution to reveal the spatiotemporal heterogeneity of ecosystem service provision in the study area [21][22][23]. The spatiotemporal reoccurrence of ESs forms bundles known as ecological service bundles, and these bundles allow the quantitative study of ESs.…”

Identifying the spatial characteristics of ecosystem service (ES) supply and demand is crucial for effective ecosystem management and restoration. Past related studies have primarily focused on balancing ES supply and demand and supply clustering, with less attention focused on the drivers of demand clustering and their spatial evolution. This study explored the spatiotemporal supply–demand dynamics in four crucial ecosystem services (ESs) in the Sichuan-Yunnan ecological buffer area region between 2005 and 2019, namely water yield, net primary production, soil conservation, and habitat quality. Self-organizing maps and geographical detectors were used to classify supply–demand ES bundles as their main drivers, respectively. The main results of the study included: (1) A decline in habitat quality, whereas net primary productivity, water yield, and soil conservation increased. However, there were increasing demands for habitat quality, water yield, and net primary productivity, despite the decrease in demand for soil conservation. (2) Demand for habitat quality was met by supply, whereas there were deficits in soil conservation, water yield, and net primary productivity, which contributed to the demand in the east exceeding that elsewhere. (3) The proportion of ES bundle 2 increased, whereas those of the remaining ES bundles declined. Similarly, the areas of ES demand bundles (ESDBs) 1 and 4 decreased, whereas those of 2 and 3 increased. While the spatial extent of the ESBs remained relatively stable, those of the ESDBs in the northern regions increased. Key factors influencing the spatial distribution of ES supply include human activities, population density, and precipitation, whereas land use, population density, and the human activity index primarily affect demand distribution. The results of this study can act as a reference for comprehensive regional ecosystem management.

“…Supply and demand reflect the flow of ecosystem services through ecosystems and human social systems. The relationship between the supply of and demand for ecosystem services can effectively reflect the state of regional economic development and the state of the ecological environment [13]. On the one hand, the amount of ecological products and services that water ecosystems can provide is no longer able to meet the increasing demand needed for human society to develop, and on the other hand, human society's investment in water ecology is not enough to support the restoration of water ecosystems' ability to supply goods [14][15][16].…”

The imbalance between the supply and demand of ecological products between society and ecosystems is an important cause of a series of water ecological problems, and water ecological restoration projects aim to improve the above supply–demand relationship by means of inputs from the social side. For this reason, this paper takes the Yellow River Delta region as an example to launch a study on the assessment of the effectiveness of water ecological restoration projects from the perspective of the supply and demand of ecological products. Specifically, the level of the supply and demand of ecological products, as well as the relationship between the supply and the demand in the studied area, were measured using the equivalent factor approach and the water footprint approach, and the effects of the Yellow River Delta hydro-ecological restoration project were assessed by integrating the following four metrics: land use, supply of ecological products (ecosystem services), demand for ecological products, and the relationship between the supply of and demand for ecological products. The results of this study show that although the hydro-ecological restoration project continues to replenish water resources in the Yellow River Delta region, and promotes the level of ecological product supply in the study area through the restoration of wetlands and water, the growing and excessive demand for ecological products in the study area still puts the local ecosystems at risk of degradation. In the future, the Yellow River Delta region should continue to control the scale of land for production and living on the supply side of ecological products and increase its investment in water ecological restoration, while establishing a highly efficient mode of ecological product development and utilization and a reasonable mechanism for the payment of ecological products on the demand side. In addition, the Yellow River Delta region needs to pay attention to the impacts of rising sea levels and other climatic problems on ecological restoration.
