“…Zhang et al [ 45 ] found similar results in their study of Wuhan, and the main reason for this was that water bodies have the highest value coefficient and larger area, which could provide greater ecological benefits. However, the ESVs of 11 ecosystem services in farmland ecosystems and forestland ecosystems decreased with the reduction of natural vegetation such as farmland and forestland, which was consistent with the results of Dai et al [ 46 ]. This was mainly because farmland was a major contributor to soil formation and conservation and food production, whereas forests played an important role in biodiversity conservation, climate regulation, and gas regulation [ 31 , 47 ].…”

Rapid urbanization and industrialization and enhanced ecological protection measures have greatly influenced landscape change, which has exacerbated regional landscape competition and conflicts and indirectly affected the supply of ecosystem services. Clarifying the relationship between ecosystem service change and landscape change is useful for understanding the impact of ecosystem conversion on socio-economic development and providing a knowledge base for relevant policy decisions. In this study, we used remote sensing technology to process Landsat TM/ETM+/OLI imageries, combined with transformation analysis and kernel density analysis to study the spatial and temporal characteristics of land use change in Wuhan City from 1980 to 2020. We also estimated the ESV in the region using the improved unit area value equivalent method to reveal the trends of ESV changes in Wuhan. The results showed that land use changes in Wuhan during 1980–2020 occurred mainly in terms of decreases in farmland, forestland, and bare land, as well as increases in built-up land and water bodies. The built-up land was mainly concentrated in the main urban areas, but its area in each suburban area has increased in recent years. In contrast, farmland was mainly distributed in suburban areas, and its area has been decreasing in recent years due to the impact of urban expansion. However, the reduction is compensated for by the reclamation of ecological land such as grassland and forestland, which has aggravated the loss of ecosystem service values in the study area. In addition, human activities such as urban expansion have increased the demand for water resources, while also leading to ecological problems such as water scarcity and water quality degradation, which have caused serious losses to key ecosystem services in Wuhan city. Therefore, in order to alleviate the competition and conflicts in the landscape and mitigate the loss of ecosystem service values in this area, we have proposed some constructive suggestions for future urban planning and water quality improvements in Wuhan. The focus of these suggestions is on controlling the expansion of built-up land, as well as the conservation of ecological land and resource protection. Meanwhile, our findings can also provide reference information for land resource planning and ecological monitoring, and help researchers to understand the contribution of ecosystem service functions in relation to socio-economic development.

“…Due to monsoon weather and flat terrain in the basin, floods occur frequently; thus, the value of water regulation is extremely high. During the past two decades, human activities and decreases in vegetation have weakened the water regulation service, as reported by Dai et al (2020), and the water regulation ability in urban centres is lower than that in suburban areas. The areas that experienced changes in climate regulation are similar to those that experienced changes in water regulation, and these regions were distributed in counties where the Yangtze River flows, with an overall strengthening trend.…”

Ecosystem service (ES) supply and demand assessment is essential for understanding the inner relationships between ecosystems and humans and is useful when formulating future ecological policies. This study analyses the spatial and temporal variations in key ESs in the Yangtze River Middle Reaches Urban Agglomeration to understand the relationship with human demand. First, the InVEST model is used to quantify the spatial and temporal changes in the key ESs from 2000 to 2019, and a supply–demand index is used to explore the supply–demand relationship at the county scale. Second, ES bundle is applied to analyse the relationships among ESs in different supply–demand balance areas. Finally, different ecological protection scenarios are proposed to simulate the supply–demand relationship in 2040. The results show that (1) the impacts of ecological factors on the ES supply are greater than socioeconomic factors, especially the precipitation and distance from the Yangtze River. (2) Regions of supply–demand imbalance are mainly concentrated in provincial centres and the surrounding cities, especially in the Wuhan city circle. (3) Each ES in regions of balanced supply and demand is well-balanced, and ESs in regions of supply-demand imbalance are dominated by one service. (4) Among the simulated scenarios, the climate regulation protection scenario in 2040 yields the optimal supply–demand result. This study can contribute to future management decision-making regarding the balance between the supply and demand of ecosystem services.

“…There was a large difference in the type of vegetation growth and vegetation ecological water storage between summer and winter [50], this led to the fact that NDVI also varies within the region in different seasons. The country's rapid economic development, industrial development, and urban expansion all affected the quality of the original ecological environment between 2000 and 2019 [51]. With the rapid development of the Yangtze River Economic Zone and the advancement of urbanization [52], the increasing intensity of human activity has had a negative impact on the ecological environment in the MYRB [53], the temperature has also risen between 2000 and 2019 [43], greatly affecting the ecological quality of the MYRB.…”

Ecological environment quality is a long-term continuous concept that is affected by various environmental factors. Its assessment has important implications for implementing the planning and protection of dynamic regional ecosystems. Therefore, this study attempted to obtain these indicators (green, dry, wet, heat) through the Google Earth Engine (GEE) platform, and then coupled the ecological environment quality index in the middle reaches of the Yangtze River Basin (MYRB) between 2000 and 2019, based on the remote sensing ecological index (RSEI). The major results show that: (1) changes in the four indicators in summer were more obvious than those in winter, and the changes were concentrated in the central and northern regions of the MYRB; (2) both the modified normalized difference water index (MNDWI) and normalized differential build-up and bare soil index (NDBI) in summer and winter have higher weighting ratios, implying that water body changes and human activities had a greater impact on the ecological environment; and (3) ecological environment quality in the MYRB between 2000 and 2019 was relatively flat. The ecological conditions began to deteriorate in 2008, and substantial ecological degradation was noted in some areas between 2008 and 2019 (18.7% in the central region, 16.0% in the eastern region). The MYRB has an important position in the Yangtze River economic belt and is an important part of the Yangtze River protection. This research could provide a theoretical basis and decision support for the development and protection of the Yangtze River Basin (YRB) green economy.
