“…Both precipitation and temperature in the TRB showed a positive trend, and various studies have demonstrated climate change's impact on the EEQ of the TRB, with different spatial precipitation and temperature variability levels, leading to impacts on different ecosystems [52][53][54]. Therefore, the specific mechanisms behind climate effects on the EEQ of the TRB will be under scrutiny in future studies [42,55].…”

“…However, in the northwest arid region, the detrimental impact of soil salinization on EEQ variation dynamics should not be overlooked. Desertification issues are predominantly attributed to land degradation due to desertification and soil salinization, as well as grassland degradation, which exacerbate the decline in soil fertility, leading to the deterioration of the ecological environment and hindering socio-economic development, particularly in agriculture [41,42]. Many scholars have incorporated salinity measures into the evaluation of EEQ; however, for basins with large areas, a single salinity index is inadequate due to diversities in soil texture and the topographical characteristics of the landform.…”

Ecological challenges resulting from soil salinization in the Tarim River Basin (TRB), exacerbated by climate change and human activities, have emphasized the need for a quick and accurate assessment of regional ecological environmental quality (EEQ) and driving mechanisms. To address this issue, this study has developed a remote-sensing ecological index with salinity adaptability (RSEISI) for EEQ assessment in the Tarim River Basin by integrating the comprehensive salinity index (CSI) into the remote-sensing ecological index (RSEI). The RSEISI enhances the sensitivity of soil salinity and characterizes the surface features of arid regions, thus expanding the applicability. Then, we used time-series analysis methods and a geodetector to quantify the spatial temporal trends and driving factors of EEQ in the TRB from 2000 to 2022. The results show that the RSEISI with salinity adaptation effectively monitors the EEQ of the TRB. The EEQ of the TRB displayed the situation of oasis expansion, desert deterioration, and glacier melting, and the multiyear average EEQ grades were dominated by medium and poor grades in desert and saline areas, while medium, good, and excellent grades were concentrated in oasis and mountainous areas. Looking at the trend of change in conjunction with land-use types, the EEQ of the TRB showed a mild degradation trend mainly in unused land, followed by a mild improvement trend in cropland and grassland. The Hurst index indicated that the EEQ of most areas of the TRB will improve in the future. Soil type, land use, precipitation, and temperature were considered to be key factors affecting the EEQ across the TRB, and changes in the EEQ were found to be the interaction of multiple factors. This study may provide innovative concepts and methodologies, scientific and technological support for ecological management, and green development models in the northwest arid zone.

“…Reasonable ecological patterns both create a good landscape effect and also effectively alleviate the impact of floods and other disasters and enhance the disaster preparedness ability of landscapes [51]. The ecological treatment project has improved the vegetation coverage rate in KRDCA and effectively alleviated the threat of heavy rainfall and other disasters to the rural landscape and to the safety of villager lives and property [52,53]. From the perspective of ecosystem vulnerability, this paper considers the two dimensions of ecological pressure and ecological vegetation sensitivity to evaluate the status quo of rural ecosystem vulnerability.…”

The ecological rehabilitation project has greatly curbed the serious problem of karst rocky desertification (KRD) in southern China and significantly changed the ecological environment and landscape pattern of the karst rocky desertification control areas (KRDCA). As one of the most important social–ecological fragile areas in the world, rural landscapes in KRDCA still show a strong sensitivity to disturbance. To reduce risks and improve the resilience of landscapes, this paper constructs a framework for assessing rural landscape resilience in KRDCA from the three dimensions of ecology, engineering, and social culture, based on the concept of resilience defined by the United Nations International Agency for Disaster Reduction. Considering the characteristics of rural landscapes in KRDCA, we select typical villages for empirical study. The results show the following: (1) The KRDCA is highly sensitive to natural disasters due to its special dual geomorphic structure characteristics. The disaster preparedness capacity of villages is the key factor determining the resilience of rural landscapes. The analysis of the disaster preparedness capacities of rural landscape structures with different vulnerability characteristics can be used as an effective means of evaluating the resilience level of rural landscapes in KRDCA. (2) Based on the empirical analysis of Fanhua village, which is a typical KRDCA in southern China, we found that the ecological system and engineering system of the village landscape have high resilience, while the resilience of the social and cultural systems are weak. This is due to the fact that the large number of rural population emigration in recent years has resulted in villages being at the key node of the reorganization of the social and cultural value system. The unstable sociocultural value system reduces the ability of rural landscapes to adapt to disturbance or environmental change. The study results could guide improvement strategies for subsequent landscape planning and inspire new ideas and methods for the implementation of rural revitalization strategies and the improvement of landscape resilience in KRDCA.
