“…From 1987 to 2020, the coal mining industry in Shanxi Province and Yangquan City experienced a period of vigorous development, with raw coal production increasing by 328.33% and 459.59%, respectively (Figure 11). Frequent mining activities have greatly promoted the rise and development of coal resource-based cities in Shanxi Province and also had a negative impact on the local ecological environment [11,18,25]. Yangquan Coal Mine is located in the Loess Plateau with a fragile ecological environment.…”

“…The accumulation of coal gangue not only occupies a large amount of land but is also prone to raising dust and spontaneous combustion, and even causes geological disasters, therefore endangering the ecological safety of the mining area and human health [9]. Particularly in the Loess Plateau, where coal reserves are abundant but the ecological environment is fragile, the above ecological environmental problems are more prominent [10,11]. Therefore, the effective monitoring and evaluation of the surface ecological environment in the coal mining areas of the Loess Plateau is of great significance for the rational development of coal resources and the implementation of ecological restoration strategies by the national and local governments.…”

Over the last few years, under the combined effects of climate change and human factors, the ecological environment of coal mining areas has undergone tremendous changes. Therefore, the rapid and accurate quantitative assessments of the temporal and spatial evolution of the ecological environment quality is of great significance for the ecological restoration and development planning of coal mining areas. This study applied the ecological environment index after topographic correction to improve the remote sensing ecological index (RSEI). Based on a series of Landsat images, the ecological environment quality of Yangquan Coal Mine in Shanxi Province from 1987 to 2020 was monitored and evaluated by an improved remote sensing ecological index. The results show that after topographic correction, the topographic effect of the remote sensing ecological index was greatly reduced, and its practicability was improved. From 1987 to 2020, the ecological environment quality of Yangquan Coal Mine was improved, and the mean of the RSEI increased from 0.4294 to 0.6379. The ecological environment quality of the six coal mines in the study area was improved. Among the six coal gangue dumps, the ecological environmental quality of D1, D2, D3, and D4 has improved, and the ecological environment quality of D5 and D6 worsened. The percentages of improved, unchanged, and degraded ecological environment quality in the entire coal mining area were 77.08%, 0.99%, and 21.93%, respectively. The global Moran’s index was between 0.7929 and 0.9057, and it was shown that there was a strong positive correlation between the ecological environmental qualities of the study area, and that its spatial distribution was clustered rather than random. The LISA cluster map showed that the aggregation and dispersion degree of ecological environment quality was mainly high–high clustering and low–low clustering over the whole stage. During the study period, temperature and precipitation had limited impacts on the ecological environment quality of Yangquan Coal Mine, while the coal mining activities and urbanization construction seriously affected the local ecological environment quality and the implementation of ecological restoration policies, regulations, and measures was the main reason for the improvement of the ecological environment quality.

“…Its average annual rainfall is 456mm, mainly in July and August. Recently, the rapid development of heavy industries such as coal mining and metal smelting has led to a significant increase in extreme weather events, especially in the periphery of the built-up area (Zhao et al, 2021). In addition, the limited land resources of the river valley plain lead to the expansion of construction land into the surroundings, which deteriorates the health of the regional environment, and threatens the stability of the entire ecological pattern.…”

The cooling effect of green infrastructure (GI) is becoming a hot topic on mitigating the urban heat island (UHI) effect. Alterations to the green space are a viable solution for reducing land surface temperature (LST), yet few studies provide specific guidance for landscape planning adapted to the different regions. This paper proposed and defined the landscape complexity and the threshold value of cooling effect (TVoE). Results find that: (1) GI provides a better cooling effect in the densely built-up area than the green belt; (2) GI with a simple form, aggregated configuration, and low patch density had a better cooling intensity; (3) In the densely built-up area, TVoE of the forest area is 4.5 ha, while in the green belt, TVoE of the forest and grassland area is 9 ha and 2.25 ha. These conclusions will help the planners to reduce LST effectively, and employ environmentally sustainable planning.

“…In 2018, Xu used the principal component analysis method to construct the remote sensing ecological index (RSEI) with the help of four remote sensing ecological elements: greenness, heat, wetness, and dryness [24]. This index has the advantages of high efficiency, objectivity, and accuracy in monitoring the changes in regional eco-environment quality, and it has been widely used in the evaluation of urban eco-environments [25][26][27]. In addition, the nighttime light (NTL) observed by the spaceborne sensor can objectively and accurately reflect regional human activities from the grid scale [28,29].…”

Since the 21st century, China’s rapid urban development has had profound impacts on the regional eco-environment and posed severe threats to regional sustainable development. In order to scientifically evaluate the coupling relationship between urban development and the eco-environment in the Guanzhong region, in this paper, by combining nighttime lighting data and MODIS data in 2001, 2010 and 2018, we applied an overall coupling model and a coordination model to discuss the spatial–temporal coupling and coordination relationship between urban development and the eco-environment. The results showed the following: (1) From 2001 to 2018, the urbanization development in the Guanzhong region significantly improved and the links between cities were continuously strengthened, but the degree of contact still needed to be improved. (2) The eco-environment quality in the Guanzhong region slightly increased, but the overall level was low. The structure of the eco-environment quality grade changed greatly, and “Good” grades changed to “Very Good”. (3) During 2001–2018, the overall coupling situation between urban development and the eco-environment strengthened and the degree of coordination increased. The coupling coordinator subtype gradually transformed from system balanced development into system balanced development, the ecology lag type, and the urban development lag type coexisting phenomenon. The results of the study suggest that future urban development planning and ecological protection policies need to take the coordinated coupling between urban development and the eco-environment into account.
