“…Studies indicate that in the Wuwei Basin, located in the SYB's middle reaches, human activities such as groundwater extraction influenced groundwater levels by 63%, whereas climate factors contributed 37%. In the Minqin Basin at the lower reaches, the contributions from human activities and climate factors were 79% and 21%, respectively [32]. The main dynamics influencing groundwater level variations in the Minqin Basin encompass inflow from the Hongyashan Reservoir and groundwater extraction.…”

Groundwater overexploitation for agricultural irrigation is prone to lead to numerous ecological concerns. This study delved into the present distribution and recent trend of groundwater levels in the plain areas of the Hexi Corridor in Northwest China according to the groundwater level depth (GWD) data from 264 monitoring wells in the Shiyang River Basin (SYB) and 107 in the Shule River Basin (SLB), recorded annually in April from 2019 to 2023. The key findings include the following: (1) Over the five-year span, the SYB’s GWD experienced change rates (CRs) ranging from −12.17 to 9.11 m/a (average: −0.13 m/a), with the number of monitoring wells showing increased and decreased GWDs accounting for 50% and 50%, respectively. By contrast, the SLB’s GWD exhibited CRs ranging from −1.87 to 2.06 m/a (average: 0.01 m/a), with the number of monitoring wells showing increased and decreased GWDs accounting for 52% and 48%, respectively; (2) the Wuwei (CR = 0.09 m/a) and Changning (0.58 m/a) basins in the SYB and the Yumen (0.06 m/a), Guazhou (0.05 m/a), and Huahai (0.03 m/a) basins in the SLB, witnessed rising groundwater levels. In contrast, the Minqin Basin (0.09 m/a) in the SYB and the southern Dunhuang Basin (0.04 m/a) in the SLB witnessed declines in the groundwater levels; (3) The groundwater sustainability assessment showed that the groundwater is still extremely unsustainable. This study’s insights are instrumental in targeted treatment, as well as the preparation and adjustment of sustainable groundwater protection strategies.

“…Similar characteristics exist in the SRB; due to vegetation degradation, the NDVI in the east and west upper reaches of the SRB and the artificial oasis areas in the central and lower regions decreased significantly (Figure 2c). HA has an significant impact on the ecologically fragile arid zone [78], and to a certain extent, it will cause further exacerbation of the ecological environment [79,80]. HA are not only reflected in the process of LUCC; the change of groundwater should not be ignored [81].…”

Arid zone ecosystems, integral to terrestrial systems, exhibit relatively low stability and are prone to influences from human activities and climate change. To elucidate the influence on the ecological environment of the arid zone by climate change and human activities, the paper takes normalized difference vegetation index (NDVI) as an evaluation index of the ecosystem and uses trend analysis to evaluation of NDVI variation characteristics in the Shiyang River Basin (SRB) from 1990 to 2020. Simultaneously using methods such as partial correlation analysis and residual analysis to evaluate the impact of climate change and human activities on NDVI changes. This study yielded several key findings: (1) The NDVI in the SRB exhibits an increasing trend of 0.034/10a in the interannual variation. (2) The relation cooperatives between NDVI and the deviation of precipitation and temperature in the SRB range from −0.735 to 0.770 and −0.602 to 0.773, respectively. (3) The changes in land use and groundwater depth in the SRB have a certain impact on NDVI changes. (4) The proportion of areas with significant contributions (contribution rate greater than 60%) from climate change and human activities to NDVI change is 33.5% and 22.5%, respectively.

In this study, an environmental comparison of hybrid, fuel cell and gasoline passenger vehicles is performed with the application of life cycle assessment (LCA) methodology. Unlike in a classic LCA, the vehicle cycle and fuel cycle of vehicles have both been modeled to cover vehicles with the full life time.According to the assumptions, the total energy consumption of the hybrid and fuel cell vehicles are respectively 27% and 37% lower than that of the gasoline vehicle. The GHG emission of the hybrid and fuel cell vehicles are respectively 27% and 44% lower than that of the gasoline vehicle. The results of the study show that the FCV is the one that presents the lower LCA energy consumption and GHG emission compared with the HEV.
