“…Geodetector, on the other hand, can not only quantitatively detect the interaction between different factors but also judge the significant differences in the influences of different driving factors on the research objects. According to the analysis results of driving factors, it is clear that land-use intensity is the most important driving factor for ESV change, and NDVI, slope, and population density also have significant effects on ESV, which has been verified in previous studies [47,[52][53][54][55]. The type and quantity of data, the method of dispersion, and the carrier employed by the Geodetector may be factors in why elevation, temperature, precipitation, soil erosion, and GDP failed the significance test.…”

Urbanization and human activity have recently resulted in land use/cover change (LUCC), which has had a detrimental effect on the biological environment, on keeping the ecosystem’s sustainable growth and on comprehending the ecosystem’s quality and changes over the past 20 years in the central Yunnan urban agglomeration. The equivalent factor method and hotspot analysis were used to analyze the spatio-temporal changes in land use and ecosystem service value (ESV) in the urban agglomerations of central Yunnan province, and the effects of land use change on ESV were then examined. This study is based on the grid data of land use in 2000, 2005, 2010, 2015, and 2020. Finally, Geodetector was used to investigate the possible causes of ESV. The results showed that: (1) The urban agglomerations in central Yunnan’s land-use structure and pattern clearly changed between 2000 and 2020, with continual declines in grassland, cultivated land, and woodland, and constant increases in construction land. There was significant growth in both speed and area. (2) The average ESV of the land decreased consistently, the hotspot areas shrank, and the cold-spot areas grew as the ecosystem service function declined and the total amount of ESV decreased by 1.517 billion Yuan. These events were mostly explained by an increase in construction land and a decrease in grassland, cultivated land, and woodland. (3) The synergistic effect of numerous factors is what causes the change in ESV in the urban agglomerations of central Yunnan. The key forces behind ESV change in the research area were land-use intensity, normalized difference vegetation index (NDVI), slope, and people density. The results can help decision makers establish policies for ecological conservation and land use.

“…These in ows are the main contributors to DTL outside the ood season in July and August, and together with the Yangtze River, they constitute the unique watershed pattern of DTL. This unique pattern creates cyclic uctuations in DTL's water level, providing a distinctive habitat for numerous ora and fauna (Li et al, 2022).…”

The Dongting Lake (DTL) area constitutes a naturally interconnected lake wetland. Alterations in river-lake relationships are poised to profoundly modify the ecological condition of lake region. This study aims to investigate the co-evolutionary attributes and ecological response mechanisms involving the Yangtze River, the Four Rivers within the DTL basin (DFR), and DTL itself during extreme hydrological events. Amidst the trajectory of wetland contraction, the impact of shifts in river-lake relationships on the wetland's state remains unclear. Thus, we employ cross-wavelet transformation and the multifractal method to establish a framework for co-evolution between rivers and lake. Through this framework, we analyze the varying progression of hydrological relationships within the river-lake system and their corresponding responses. The findings reveal that instances of low-water events in DTL predominantly manifest during winter and spring. These low-water events exhibit a propensity to occur frequently and irregularly, except during July-August, coinciding with the Yangtze River's flood regulation period. Additionally, the DFR-DTL system demonstrates a wider periodicity and more pronounced positive continuity, serving as the principal impetus behind the ecological evolution of DTL. Simultaneously, alterations in the inundation status across DTL regions display an ascending trend from west to east. The predominant influence of the Yuan River and the Yangtze River leads to the majority of water degradation areas being concentrated in the western DTL region, where sedimentation is particularly severe. The changes in river-lake relationships showcase substantial variability and exert distinct impacts on DTL's hydrological evolution through a range of confluence regions.

“…In that sense, ES hotspot maps have potential benefits that can be transmitted to stakeholders to improve management planning (Hauck et al, 2013). Also, the implication of knowing this information provides a scientific basis for making relevant decisions in a territory (Li et al, 2022). Consequently, these ES hotspot watersheds should get the priority of being strategically managed for maintaining their essential ecosystems.…”

Glaciers supply multiple ecosystem services that are threatened by climate change. The retreat and disappearance of tropical glaciers is an important dynamic that affects ecosystems and local communities. The knowledge of the impacts of this land-change dynamics on the supply of ecosystem services is lacking. In that sense, the assessment developed can provide evidence about the costs and benefits of promoting conservation and human well-being at the same time. Then, the main objective of this research is to determine the spatial–temporal changes and their effects on the economic value of ecosystem services in a glacial retreat environment. We selected the Marangani district as a study area. It comprises the La Raya Mountain range in the Andes. The assessments were carried out across two scales of observation: the municipality and the watershed level. Here, we process spectral information from Landsat Sensor using the Random Forest algorithm in the Google Earth Engine platform to classify 10 biomes. It was carried out over more than 30 years (from 1986 to 2019). After that, ecosystem services provided by the biomes were valued using the transfer method. This research shows that at the municipality level, almost all the LULCs faced variations over time, and the glaciers had the highest change, accumulating a ratio of –85.51%, whereas at the watershed level, a higher tendency of land changes is observed in the areas without glaciers, and those with glacier areas count on permanent larger bofedales. At the municipality level, the economic value of ecosystems shows that bofedales and water surfaces are the LULCs that supply the highest ecosystem services (∼33,000 USD ha−1 yr−1 each). In addition, without the inflation adjustment, the total ESV is on a trajectory of losing ESV (–$9.67 × 106). In the watersheds with glacier retreat, significant quantity of bofedales and natural grasslands controls the fluctuations of ESV. These high-mountain watersheds play an essential role in providing benefits and value to local communities. In general, the municipality level indicates the trajectory of changes in the district, whereas the watershed scale shows the urgency for implementing spatial conservation actions.
