“…In addition, this study only explored the relationships for a single year, and the temporal dynamics of the relationships have been not well understood. Furthermore, different urbanization levels may in uence the relationship (Xia et al 2024). Therefore, there is a need to quantify the long-term dynamics of ecosystem services and human well-being and their relationships at the town and village scales, and to incorporate different levels of urbanization in order to deepen the understanding of the coupling mechanism of human-environment systems.…”

“…The pilot demonstration area is located in the core area of the Yangtze River Delta Ecological Greening Development Demonstration Area. This area is an important water conservation area with outstanding ecological function and it is undergoing rapid urbanization with intense interaction between humans and the environment (Xia et al 2024). Therefore, it can be regarded as a favourable area for us to study the relationship between ES and HWB at multi-ner scales in the urbanized area.…”

Context: The relationships between ecosystem services (ES) and human well-being (HWB) have been found to be influenced by geographic locations and socioeconomic development, and vary from local to global scales. However, there is a lack of comparative analyses at fine administrative scales such as town and village scales. Objective: This study took the core region of the Yangtze River Delta of China as the study area to examine the spatial characteristics of the value of ES and the subjective perception of HWB and compare their relationships at the town and village scales. Methods: 9 ES and 11 HWB indicators were quantified using the ecosystem service equivalence factor method and the questionnaire survey, respectively. The ES-HWB relationships were then investigated using Spearman's correlation analysis. Results: The value of ES per unit area in the study area in 2020 was about 15,202.90 USD/ha, nearly three times the average level in China, but the per capita value was relatively low, at 322.11 USD/person. The score of subjective perception of HWB was relatively high, especially for the dimensions of social relations, health, and safety. As spatial scales decreased from town to village and thematic scales increased from secondary to primary indicators, the strength of the ES-HWB correlations diminished and their direction changed as well. According to secondary indicators, most of the ES-HWB relationships were positive at the town scale but became negative or nonexistent at the village scale. Conclusions: The ES-HWB relationships may vary unpredictably at local scales (e.g., counties). But “local scale” is not always local, because at the town and village scales the relationships can still vary. Thus, better understanding the relationships requires studies at multiple and broader scales and calls for the caution when using the aggregating indicators because they can also lead to different ES-HWB relationships.

“…The watershed data were obtained by processing DEM data using ArcSWAT software. The parameters including load, efficiency, and critical length in the InVEST model were obtained from the relevant studies (Xia et al, 2020;Fang et al, 2021;Xia et al, 2022;Wang and Xu, 2023) and the InVEST User Guide, and these parameters were adjusted to match the local characteristics.…”

Introduction: Water is an important ecological factor, and non-point source pollution (NPSP) seriously affects water security. In recent years, NPSP has affected water security and human survival in China.Methods: The Luhun Lake Basin has been selected as an example region of Yellow River Basin (YRB) in China, and the trends and impacts of nitrogen (N) and phosphorus (P) has been quantitatively evaluated by using geographic information system (GIS), remote sensing (RS) and InVEST model.Results: The results show that (1) the arable land and water bodies decreased, while forest land, grass land, construction land and unutilized land increased in the 20 years. The average annual precipitation increased from the northeast to the southwest in the 20 years; (2) the N and P exports first increased in 2000–2010 and then decreased in 2010–2020, and finally increased in 2000–2020; (3) with the increase of precipitation, the N and P exports decreased in 2000–2010, 2010–2020 and 2000–2020; (4) the amount of N and P exports on arable land and construction land were more than that on the other land use types. The N and P exports on each land use type all first increased and then decreased, and the overall change trend all increased in 2000–2020.Discussion: This study demonstrates how geographic information system (GIS), remote sensing (RS) and InVEST model can be used to assess nitrogen and phosphorus pollution in data scarce regions.

“…In Xining, the largest city on the Tibetan Plateau, the annual water use was 530 million m 3 in 2020, accounting for less than 1/3 of the available water resource which was 1.7 billion m 3 (QWRD 2021). But the local water resource has been polluted by both non-point and point sources (Xia et al 2022), and is no longer suitable for urban water supply. Instead of pollution control and treatment, WTPs have been adopted as the primary approach to dealing with the water shortage problem in Xining.…”

“…Existing and potential urban water source catchments, especially drinking water sources, must be protected against pollution and restored ecologically as needed. The supply and demand of water purification service in a region need to be balanced by optimizing landscape patterns, especially for urban areas in the upper reach of major rivers (Yu et al 2019;Xia et al 2022). 5.…”
