“…Geodetector is a statistical analysis method based on spatial differentiation theory [ 55 ]. It can reflect the similarity of the same region and the difference of different regions, so as to obtain the spatially distinctive features of geographical phenomena and the driving factors behind them [ 56 ]. The Geodetector includes four modules: factor detection, interactive detection etc.…”

“…Field validation of the EECC is needed in the future [41]. Second, natural factors and human activities often interact and jointly affect regional ecological environment changes [42]. In the future, the drivers of EECC should be explored in depth, the interactions between different factors should be clarified, and the underlying causes of changes in EECC should be revealed.…”

Ecotourism is the main trend of global tourism development, and evaluating the ecotourism environmental carrying capacity (EECC) of ecologically fragile areas can provide a scientific basis for the sustainable development of regional tourism. This study uses the typical fragile mountain area, the Qilian Mountains (QLMs), as an example and analyzes the spatial and temporal changes in EECC by constructing an evaluation indicator system of EECC, which is based on the framework of “natural ecological environment support—socio-economic pressure—tourism activity pressure”. In the results, it is found that the natural ecological environment support, socio-economic pressure, and tourism activity pressure in the QLMs all present a spatial distribution pattern of higher in the southeast and lower in the northwest. From a temporal perspective, most of the indicators of different subsystems show an increasing trend. The whole area of EECC in the QLMs shows an increasing trend in 85.4% of the region, while the EECC in some areas in the southeastern and northern parts shows a decreasing trend. Comparing different time periods, it is found that the EECC in the whole region shows an increasing trend from 2000 to 2010, while the proportion of areas with a decreasing trend in EECC from 2010 to 2018 reaches 67.1%. The research results can provide a scientific basis for the sustainable development of ecotourism in the QLMs and other similar regions in the world, and they further contribute to the protection of the ecological environment.

“…The 'Bohai granary' plan, human activities such as increasing greenery in the living environments of local residents, and seawater intrusion caused by the decline in the Yellow River's sediment content have affected spatio-temporal changes in regional salinization [29]. From 2000 to 2009, the mild salinization and non-salinized areas significantly decreased, whereas the moderate and severe salinization areas increased significantly.…”

Using the kernel normalized difference vegetation index (KNDVI) to monitor soil salinization has great advantages; however, approaches using KNDVI and a feature space model to monitor salinization have not yet been reported. In this study, the KNDVI, normalized difference vegetation index (NDVI), extended difference vegetation index (EDVI), green normalized difference vegetation index (TGDVI), modified soil-adjusted vegetation index (MSAVI), and salt index (SI) were used to establish five feature space monitoring indices for salinization. The spatio-temporal evolution pattern of soil salinization in the Yellow River Delta from 2000 to 2020 was analyzed based on the optimal monitoring index. The remote sensing monitoring index model based on KNDVI-SI’s point-to-point mode had the best applicability with R2 = 0.93, followed by EDVI-SI’s salinization monitoring index model with R2 = 0.90. From 2000 to 2020, soil salinization in the Yellow River Delta followed an exacerbating then improving trend. Soil salinization was more severe in the northern and eastern coastal areas of the Yellow River Delta. These results are conducive to salinization restoration and control in the Yellow River Delta.
