“…Spearman's correlation coefficients were applied to determine the correlation among the soil physical properties. Besides, redundancy analysis (RDA) was widely used to analyze the impact of each driving force by expounding the correlation between response and explanatory variables (Gabarrón et al, 2018; Zhang et al, 2021). In this study, the RDA was performed to evaluate the effect of soil physical properties (explanatory variables) on dyeing indices (response variables).…”

The long-term cultivation of banana crops (Musa nana Lour.) has caused improper utilization of soil and water resources. However, the effect of the banana plantation regime on soil water flow pattern is still poorly understood. This study focused on the dominant pattern of soil water movement in the 1-year (B1) and 4-year (B2) old banana plantations. The results showed that: (1) the soil physical properties showed variability with soil depths, especially obvious changes from surface to 40 cm depth, which had restriction on soil infiltration in different depths. ( 2) The saturated hydraulic conductivity (Ks) decreased with the increasing distance from the banana stem.Moreover, the Ks in the B2 plot increased by 65.5% compared to the B1 plot at the soil layer 0-20 cm. (3) Preferential flow was the main path of soil water transport and was significantly influenced by soil bulk density, porosity, and root systems.Redundancy analysis (RDA) showed that banana root biomass was the most prominent factor influencing the dyed area. (4) The soil infiltrability and the preferential flow degree of both B1 and B2 plots were stronger in the root zone than those in the non-root zone. Such results were attributed to the root systems around the banana stem that were more developed than those far away from the stem (more accurately pseudostems); a large number of pore channels formed around the root systems that promoted the preferential flow. Or results suggest that banana root was the important factor affecting soil water movement. The improvement in the root network of banana plantation regime can result in better soil physical properties. This knowledge will be vital for the sustainable cultivation and irrigation of banana crops.

“…Oasis changes are influenced by both natural resource conditions and human activities [18]. In order to comprehensively and quantitatively analyze the drivers of oasis area change, we selected 10 variables, including both natural factors (average annual precipitation, average annual temperature and wind) and anthropogenic factors (population, GDP, primary industry, secondary industry, tertiary industry, livestock stock, and grain yield), and conducted the correlation analysis between the area change and the ten influencing factors through Pearson correlation [48].…”

“…In recent years, researchers have carried out a lot of research on the spatial and temporal changes of the oasis in arid zones [7][8][9][10][11][12][13][14][15][16][17][18], greatly advancing our knowledge on the vegetation coverage change [19], land use change [11], landscape pattern of oasis [20], the driving forces of oasis change [4], oasis stability [21], and oasis land-use change prediction [17]. The research areas of the oasis in China are mostly concentrated in the main distribution areas of the oasis such as Xinjiang [22,23] and the Hexi Corridor of Gansu Province [24][25][26][27].…”

“…Oasis change is closely related to natural and anthropogenic factors, however, previous studies [18,19] have paid more attention to the anthropogenic effect on oasis change. The finite nature and uneven distribution pattern of soil and water resources are the dominant factors controlling the size and distribution of oases [37], and topographic factors such as slope, aspect, and elevation directly or indirectly influence their extension and distribution [38].…”

The variability of the natural environment and the complexity of human activities result in dynamic changes in oasis areas, which is directly related to the sustainable development of arid and semi-arid areas. In order to better balance economic development and environmentally sustainable development, based on land use data and social and economic data from 1980 to 2015, this paper analyzed the oasis change characteristics under natural and human factors in the Shiyang River Basin in Northwest China. The results indicated that the oasis in the Shiyang River Basin showed an expansion trend from 1980 to 2015, with the expansion mainly occurring in the diluvial and alluvial fan, and along the middle and lower reaches of the river. The oasis changed actively in areas at an elevation of 1350 m, with a slope of 2°, at the distance of 1500 m to rivers, and with precipitation of 120 mm and temperature of 15 °C. Furthermore, the oasis mainly evolved towards gentler slopes and lower altitudes, and migrated closer to rivers before 1992 and farther away from rivers afterwards. Population growth and economic development were the important inducers of oasis change, and government policies on agricultural benefits and ecological conservation also influenced the oasis change, especially after 2000. The evolution patterns of oasis distribution revealed in this study can provide a reference for promoting oasis ecological restoration and sustainable development.

“…Studying oasis evolution is an important foundation for understanding future changes in oases. Its core is to explore the direction of oasis changes (such as location and area) under the scenarios of changes in oasis driving factors, such as water resources (F. Huang & Ochoa, 2022; Z. Zhang et al., 2021). Currently, most studies focus on the directional changes of individual oases under changing environments, making it difficult to summarize global oasis change patterns (P. Chen et al., 2022; Sun et al., 2021; Xie et al., 2014).…”

The human‐environmental system in drylands is centered on oases. Despite its extent and socio‐ecological importance, understanding the dynamic changes of global oases and their human and environmental driving forces is imperative for sustainable development in drylands under global warming. Nevertheless, the dynamic changes of global oases and how they respond to the evolving environment are not well established. In this study, three criteria were summarized (i.e., existing in dryland climates, surrounded or partially surrounded by desert terrain, having a reliable source of freshwater and forming landscape units with higher vegetation coverage/productivity). A global oasis distribution map from 1995 to 2020 was generated using European Space Agency Climate Change Initiative Land Cover and GIMMS‐3G+ data (overall accuracy within a 95% confidence interval is 0.85 ± 0.01) based on overlay analysis and visual interpretation. In addition, we used geographic and temporal weighted regression methods to evaluate the potential macro‐level elements affecting both global and local oasis growth. The result showed that the global oases area in 2020 occupied an area of 191.91 Mha, and most oases existed in Asia (77.3%). The global oases area has significantly increased from 1995 to 2020 (+8.65 Mha). However, about 13.43 Mha of the global oases are desertified, indicating a high risk of desertification. Water resources, contributing 51.36% to the total driver's contribution, are key to the global oasis expansion. In the context of climate (climate variability and climate change), this research highlights the need for improved holistic water resource management for long‐term global oasis growth, particularly in developing countries where the oases' development is threatened by water scarcity and desertification.
