“…In addition, Zelm et al (2011) studied in the Netherlands and found that every 10 cm drop in the groundwater table caused by pumping would result in a loss of 9.2% of species in the affected area. Dong et al (2023) determined that mining‐induced groundwater depletion inevitably engenders retrograde succession of the surface vegetation community, resulting in a significant decline in aboveground biomass and biodiversity. Additionally, Froend and Sommer (2010) show that lower rates of groundwater level decline result in a progressive shift toward drought‐tolerant species over the long term (i.e., 33‐year period).…”

Although it is well known that groundwater significantly influences the plant communities, there have been few studies on how the soil and plant communities respond to a rapid decline of groundwater in a short time affected by coal mining. This paper focuses on the examination of changes in groundwater depth before and after coal mining and the soil‐vegetation response in a typical semi‐arid grassland coal mine area of Hulunbuir Steppe, Northeastern China. The IsoSource model, based on the dual stable isotopes of δ D and δ18O, was employed to estimate groundwater contributions to shallow soil (0–100 cm) water under different groundwater depths. The results revealed that groundwater was the dominant water source (75.7% ± 17.1%) for shallow soil water when the groundwater depth is less than 4 m, indicating that 4 m is a threshold in groundwater depth, separating groundwater‐dependent, and precipitation‐driven vegetation system in the study area. Secondly, a strong nonlinear response was observed between vegetation species, height, coverage, and the decline in groundwater. The vegetation properties were found to be the lowest in the areas where groundwater depth increased from 1.5–4 m to 4–28 m before and after coal mining. Finally, the groundwater level decline in the mining area significantly influenced the groundwater‐dependent vegetation ecosystem, the soil cation exchange capacity and organic matter reduced lead to the degradation of plant communities and the transition of mesophytes to xerophytes. Besides, the soil‐vegetation system in the non‐groundwater‐dependent area has no obvious response to the groundwater decline. These results suggest that caution should be exercised when mining in groundwater‐dependent ecosystem regions.

“…Groundwater is vital for maintaining human and livestock consumption as well as industrial and agricultural production (Wang et al, 2018).It likewise regulates the composition of plant communities (Xu et al, 2018, Dong et al, 2023 and protects ecosystem health (Jha et al, 2007, Rodriguez-Iturbe et al, 2007, Xia et al, 2021.Especially in arid and semi-arid regions with insufficient precipitation and fragile ecosystems, the contribution of groundwater to evapotranspiration can not only ensure the survival of vegetation (Naumburg et al, 2005), but also modify vegetation patterns and dynamics by affecting soil moisture (Zhu et al, 2015, Lowry et al, 2011. Therefore, it is crucial to understand how groundwater circulation and plant development are related.…”

The highway greenbelt, vigorously promoted in arid and semi-arid areas, has obvious impacts on beautifying the environment, absorbing dust, reducing noise, and maintaining soil and water. Moreover, it affects the characteristics of how water resources are distributed and the regional groundwater cycle. The Hu-Bao highway greenbelt in the northern Tumochuan Plain served as an example in this study. Based on fully grasping the characteristics of the regional groundwater system, we used the 3S classification method and combine the relevant formulas, such as ET0, to calculate the evapotranspiration and water consumption of the green belt and quantitatively analyze the impact of highway greenbelt construction on the regional groundwater cycle. The results indicated that trees, shrubs, and grasses, accounting for 42.17% of the research area, are the predominant plant types in the greening construction area. The area of shrubs is the highest, reaching 17.29%; followed by trees, occupying 15.18%. Grasslands is the smallest, accounting for 9.7%；During the growth season, the total evapotranspiration water consumption in the green belt is 471.35×104m3, whereas trees, shrubs and grasslands is 182.27×104m3, 211.14×104m3,77.94×104m3, respectively. The groundwater recharge in the study area mainly originated from the mountain front lateral recharge, and the main discharge was the evapotranspiration water consumption of green belts. The latter accounts for 3.31 percent of the former. It is obvious that the construction of highway greenbelts has a substantial impact on the distribution of groundwater resources, and long-term evapotranspiration will cause groundwater levels to decline and the amount of accessible water resources to decrease.

“…The over-exploitation of groundwater causes a decline in the water table, leading to an accumulation of soil salts and toxins, especially in drought years, in areas of high agricultural activity and increased water stress [15][16][17][18][19][20][21][22]. In China, the relationship between vegetation and groundwater burial depth, as well as the water table, water quality, and soil, has been studied in the Tarim River [23], Hei River [24], Shiyang River Basin [25,26], Sanguang River [27], Inner Mongolia Loop [28], Loess Plateau [29], Hulunbeier in Inner Mongolia [30], Ejina [31], and Gurbantunggut Desert [32,33]. Such studies have provided theoretical support for protecting the stability of vegetation in arid and semi-arid regions.…”

Vegetation and groundwater are important components of the ecological environment of oases in desert hinterlands and their relationship is crucial to ecosystem stability. In this study, Sentinel-2 data for 2016–2022 and measured groundwater burial depths were analysed for the Dariyabui Oasis in the hinterland of the Taklamakan Desert. The spatial and temporal changes in vegetation and groundwater burial depth from 2019 to 2022 were analysed based on the image–element dichotomous model of the normalised difference vegetation index, utilising the inverse distance weight interpolation method, cubic curve regression, image–element difference, slope trend analysis, and the Markov transfer matrix for determining the temporal and spatial response law between the two. Finally, the threshold value of groundwater burial depth for different vegetation cover types was clarified. The fractional vegetation cover of the Dariyabui Oasis showed a slight increase from 2016 to 2022. Vegetation in the northwest and southeast of the oasis increased, whereas vegetation decreased in the mid-north and northeast regions; 5.14% of the total area experienced increased coverage, whereas 3.35% experienced decreased coverage. The depth of groundwater in the oasis showed a pattern of gradual increase from the entrance to the end of the oasis, that is, south to north. The depth of groundwater in the oasis from 2019 to 2022 was stable, with a 4-year average depth of 4.1069 m and a maximum fluctuation of 0.4560 m. The interannual changes in the groundwater level showed an increasing trend in January–April, while groundwater levels showed a decreasing trend in May–July and August–October and remained constant in June–July and October–December. Oasis vegetation cover showed a negative correlation with groundwater depth, with a depth interval for the highest low-cover vegetation distribution of 3–6 m, and an ultimate depth threshold of 7 m. The depth interval with the highest medium-cover vegetation distribution was 3–4 m, that with the highest high-cover distribution was 2–4 m, and the ultimate depth threshold was 6 m. The depth of the oasis ranged from 3 to 6 m and the ultimate depth threshold was 7 m.
