“…From a global perspective, research on using the RSEI for monitoring the ecological environment of mining areas mainly focuses on China. Most foreign scholars still apply the RSEI to urban ecological environment monitoring [51][52][53], with few applying it to ecological environment monitoring in mining areas. This may be due to different coal mining methods in different countries, resulting in different focus and research content [54,55].…”

The remote sensing ecological index (RSEI) has been widely used in the rapid monitoring and evaluation of the regional ecological environment; however, the research on the main factors that cause changes in RSEI and the impact of human activities in the mining area on RSEI is not often explored. To this end, this paper selected the Landsat (TM/OLI) series of remote sensing images from 1986 to 2022; extracted the four important indicators of the normalized difference vegetation index (NDVI), the wetness component of the tasseled cap transformation (WET), normalized difference built-up and soil index (NDBSI), and land surface temperature (LST); calculated the remote sensing ecological index (RSEI) based on the principal component analysis method; monitored and evaluated the ecological environment changes in the Shendong Mining Area for a period of 36 years; and analyzed the driving forces that cause these ecological environment changes. The results show the following: (1) The ecological status of the study area has shown an overall upward trend during the 1986–2022 period. (2) From 1986 to 2022, the area of RSEI with a grade of 0.4–0.6 increased by 1142.74 km2, that with a grade of 0.6–0.8 increased by 124.09 km2, and that with a grade of 0.8–1.0 increased by 0.73 km2. (3) In the past 36 years, the proportion of RSEI with a positive grade difference was 97.52%, and the proportion of regions with a negative grade difference was 6.20%. (4) Rainfall is the main factor that causes changes in the regional ecological environment. By analyzing the main driving factors of ecological environment change and the relationship between human activities and RSEI, reference can be provided for the formulation of environmental protection policies and environmental planning in mining areas.

“…The land surface "dryness" is mainly reflected in buildings and bare soil in the regional environment. Therefore, the dryness indicator (normalized difference built-up and soil index, NDBSI) (Equation ( 8)) is synthesized from both the bare soil index (BSI) (Equation ( 9)) and the index-based built-up index (IBI) (Equation (10)): (10) where ρ blue denotes the blue band, ρ green denotes the green band, ρ red denotes the red band, ρ nir denotes the near-infrared band, and ρ swir1 denotes the short-infrared band 1.…”

“…Rapid urbanization has brought about economic changes and dramatic changes in land cover from natural landscapes to built-up areas due to increasing human activities [1,2]. This has led to a series of negative ecological effects [3], including land degradation [4], urban heat island [5], droughts [6], flash floods [7], biodiversity reduction [1], ecosystem cycle destruction [8] and ecosystem service decline [9], which have had significant impacts and pressures on ecology [10]. The relationship between urbanization and ecology is a complex interaction and coupling process [2].…”

Rapid urbanization in the lower Yellow River basin has greatly contributed to the socio-economic development of Northern China, but it has also exacerbated land use/land cover change, with significant impacts on ecology. Ecological quality is a comprehensive spatial and temporal measure of an ecosystem’s elements, structure and function, reflecting the ecological state under external pressures. However, how land use/land cover change affects the ecological quality during urbanization has rarely been explored. In this study, Jinan, a megacity in the lower Yellow River basin, was taken as a typical region, and the response of ecological quality to the land use/land cover change in 2000, 2010 and 2020 was retrieved using the remote sensing ecological index. For the mixed land use/land cover change types, a type-decomposition and spatial heterogeneity quantification method based on the abundance index was proposed, and the impact mechanisms of the land use/land cover change on the ecological quality were revealed by coupling with GeoDetector. The results show that: (1) Farmland and built-up areas, as the dominant land use/land cover types, were the primary factors controlling the spatial pattern of ecological quality. (2) Urban expansion and farmland protection policies resulted in the transfer of farmland and woodland to built-up areas as well as the transfer of woodland and grassland to farmland, which intensified the degradation of ecological quality. (3) Ecological protection policies prompted the transfer of farmland and grassland to woodland and the transfer of farmland to grassland as the main cause for the improvement of ecological quality. (4) Although ecological protection and urban development were implemented in parallel, uneven land use/land cover changes resulted in a 1.4 times expanded area of poorer ecological quality with increasingly serious spatial agglomeration effects. This study can provide scientific references for the ecological conservation and high-quality, sustainable development of cities in the lower Yellow River basin.

“…In 2015, the United Nations Sustainable Development Summit (UNDS) released the "2030 Agenda for Sustainable Development," calling for global progress towards sustainable development goals (Gjorgievski et al, 2021). Currently, governments and organizations worldwide are actively seeking effective responses to these global environmental issues (Lee and Kjaerulf, 2016;Lai and Eladawy, 2022). In response to these challenges, China has initiated a series of ecological protection and restoration projects (He and Shen, 2018), such as the Sanjiangyuan Ecological Protection Project and the "Three-North" Shelter Forest Program (Wang and He et al, 2021a).…”

Introduction: As the global urbanization process accelerates, the contradiction between economic development demands and ecological protection becomes increasingly prominent.Methods: In this study, we simulated the evolution of the ecological security pattern (ESP) of Pingtan Island from 2000 to 2020 by extracting the ecological sources using Remote Sensing Ecological Index (RSEI), and identifying the ecological corridors and key nodes by combining with Linkage Mapping (LM) and Circuit Theory. In addition, Geodetector was utilized to identify these major determinants affecting RSEI.Results: The results showed 1) From 2000 to 2020, the ecological environmental quality (EEQ) of Pingtan Island continued to improve, and the mean value of RSEI gradually increased from 0.47 to 0.51. 2) Univariate analysis showed that elevation and slope were the most significant factors affecting the spatial variability of the RSEI, with the interaction between slope and proportion of built-up area having a significant effect on EEQ. 3) The number and extent of ecological sources were expanded year by year with significant spatial variability. At the same time, the number and range of ecological corridors also underwent phase adjustment. 4) Further exploration of ESP of Pingtan Island in 2020 identified 32 ecological pinch points (EPPs) and 52 ecological barrier points (EBPs), which were mainly located within or near the ecological corridors, indicating key areas for future ecological restoration efforts.Discussion: These insights help to enhance urban spatial planning and ecosystem restoration on Pingtan Island and provide a blueprint for ESP development in comparable island urban environments.
