“…Referring to previous studies and combining with the natural and economic conditions of the study area ( 41 – 45 ), this article selects six factors, namely, land use types, population density, DEM, NDVI, distance from the road, and distance from water, to characterize human demand of ESs ( Table 2 ). The elevation can determine the flow of ESs by regulating the distribution of water and heat; NDVI can directly affect local climate, biodiversity, soil conservation, and other services; population density, water, and road traffic distribution are important for the development or decline of the region; land use type is a concentrated expression of human activities, which is both an influencing factor and an important carrier of various ESs ( Figure 3 ).…”

The supply–demand for ecosystem services (ESs) is the bridge between ecological security patterns (ESPs) and human wellbeing. This study proposed a research framework of ESP of “supply–demand–corridor–node” and took Xuzhou, China, as a research case, providing a new perspective for the construction of ESPs. The framework was divided into four sections: identifying the ecological source based on the ESs supply; utilizing multi-source economic-social data to characterize the demand of ESs and constructing a resistance surface; defining the ecological corridor in the study area by employing the Linkage Mapper; and identifying crucial ecological protection/restoration areas along the ecological corridor. The results showed that the area of the supply source of ESs in Xuzhou City is 573.89 km2, accounting for 5.19% of the city's total area. The spatial distribution of 105 ecological corridors revealed that there were multiple and dense ecological corridors in the middle of the city, but few in the northwest and southeast. A total of 14 ecological protection areas were located primarily in the south of the urban area, and 10 ecological restoration areas were located primarily in the middle and north of the urban area, with a total area of 4.74 km2. The findings of this article will be useful in developing ESPs and determining important ecological protection/restoration areas in Xuzhou, China. The research framework could potentially be used in other areas.

“…Some scholars have also used population density, per capita GDP and land use intensity to assess the demand for ESs comprehensively. However, such methods do not consider the speci c needs of different ESs [33]. In this study, human consumption and actual wind erosion were selected as demand indicators based on the speci city of each ESs type, where human consumption included food use, carbon emissions and water consumption.…”

“…As technology has improved, academic research on the supply and demand of ESs has grown even more prevalent, and there is a wide range of the research methods and types of ESs, but there is little applied research on the relationship between the supply and demand of ESs. Some scholars have used population density, GDP per capita and land use intensity to assess the demand for ESs [33]. However, such methods did not take into account the speci c needs of different ESs, which may lead to low accuracy in the assessment results.…”

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.

“…To determine the relative relationship between bird richness and habitat quality, we standardized the two variables using z-scores, with 0 as the standard. This analysis allowed us to gain a more comprehensive understanding of the relationship between these two variables [53]. The calculation formula for the z-score is as follows [54]:…”

Rapid global urbanization has caused habitat degradation and fragmentation, resulting in biodiversity loss and the homogenization of urban species. Birds play a crucial role as biodiversity indicators in urban environments, providing multiple ecosystem services and demonstrating sensitivity to changes in habitat. However, construction activities often disrupt urban bird habitats, leading to a decline in habitat quality. This paper proposes a framework for prioritizing habitat restoration by pinpointing bird hotspots that demand attention and considering the matching relationship between bird richness and habitat quality. Shanghai represents a typical example of the high-density megacities in China, posing a significant challenge for biodiversity conservation efforts. Utilizing the random forest (RF) model, bird richness patterns in central Shanghai were mapped, and bird hotspots were identified by calculating local spatial autocorrelation indices. From this, the habitat quality of hotspot areas was evaluated, and the restoration priority of bird habitats was determined by matching bird richness with habitat quality through z-score standardization. The results were as follows: (1) Outer-ring green spaces, large urban parks, and green areas along coasts or rivers were found to be the most important habitats for bird richness. Notably, forests emerged as a crucial habitat, with approximately 50.68% of the forested areas identified as hotspots. (2) Four habitat restoration types were identified. The high-bird-richness–low-habitat-quality area (HBR-LHQ), mainly consisting of grassland and urban construction land, was identified as a key priority for restoration due to its vulnerability to human activities. (3) The Landscape Shannon’s Diversity Index (SHDI) and Normalized Difference Vegetation Index (NDVI) are considered the most significant factors influencing the bird distribution. Our findings provide a scientifically effective framework for identifying habitat restoration priorities in high-density urban areas.
