Analysis of the impacts of climate variability on evapotranspiration (ET) is of great importance in understanding climate variability and its effect on hydrological aspects. In this study, temporal and spatial variations in reference evapotranspiration (ET 0) and actual evapotranspiration (AET) were comprehensively detected in the Taohe River Basin...
Article
Being an important desert riparian forest in the lower reaches of the Heihe River Basin, Populus euphratica Oliv. forest functions as a natural barrier in maintaining and preserving the stability of local oases. Accordingly, accurately estimating the water use of P. euphratica is important for vegetation protection and water resource allocation. To...

Ecologic patterns and community succession are generally controlled by hydrologic mechanisms, especially for plant distributions which are sensitive to habitat conditions. The hydrology characteristics of ecosystems mainly influenced plant ecological processes in water and salinity changes. In this paper, we analyzed the composition and characteris...
Article
Extensive research has found that nighttime transpiration (E n) is positively correlated to the vapour pressure deficit (VPD), that suggested E n was highest during the night under high temperatures and low humidity similarly to our site. This study used the heat ratio method to measure mature and sapling Populus euphratica sap velocity (V s), and...
Article
By bibliometric method, acupuncture-moxibustion literature from 2003 to 2013 included by SCIE and GoPubMed was analyzed. The number of annually published literature, distribution of country, agency and area, author, journal, subject category, high-frequency words and H index were analyzed to explore the current situation and development trend of ac...
Article
It is generally assumed that transpiration does not occur at night because leaf stomata are opened during the day and closed at night. Nonetheless, there is increasing evidence that the stomata are opening in many species and in a range of habitats at night. Nighttime transpiration rates are typically 5%-15% of daytime rates. This proportion of nig...

... Additionally, the increasing environmental pressures from population and economic growth might intensify in the coming decades if no effective and practical pathways are proposed to sustainably guide urbanization (Azam and Khan 2016). Ecosystem services (ESs) provide a material basis for human survival (MEA 2005) and interact with other environmental and socioeconomic factors via the agriculture-ecosystem-economy nexus (AEEN) Lu et al. 2021). In a social-ecological system encompassing agricultural, ecological, and economic components, external natural and man-made disturbances, such as climate variabilities, landscape dynamics, and policy interventions, might trigger system feedbacks and chain reactions (Haase 2021;Manuel et al. 2021). ...
... [23] In recent years, acupuncture treatment has attracted the attention of researchers studying PD. Several studies have evaluated the effectiveness and safety of acupuncture in the treatment of PD. [24][25][26][27][28] However, it is worth noting that in the reviews, the use of acupuncture combined with various interventions may conceal or exaggerate the therapeutic effect of acupuncture. Ibuprofen as a representative NSAID for the treatment of PD. ...
... WSVR has been used to simulate groundwater level in several studies, e.g. Ping et al. (2013), Suryanarayana et al. (2014), Sujay Raghavendra and Deka (2015), Ebrahimi and Rajaee (2017), Yu et al. (2018), and Band et al. (2021). On the other hand, rarely does AIG-SVR have been used in groundwater literature. ...
... Yuan et al. [41] also found that water consumption of P. euphratica exceeds that of T. ramosissima in the lower reaches of the Tarim River. A study by Yu et al. [42] that analyzed the variation in daily ET of P. euphratica and T. ramosissima in the lower reaches of the HRB found that the daily average ET of P. euphratica exceeded that of T. ramosissima. The studies mentioned above obtained results that were consistent with those of the present study for the downstream reaches of the HRB. ...
... Desert riparian forests in China are primarily distributed in the lower reaches of Tarim River (Hao et al., 2009) and Heihe River, the main inland rivers in China, and they serve as important green shelters for ecological protection and human habitation. The availability of desert riparian forest in the Ejina desert oasis in the lower reaches of Heihe River basin and Tarim River basin had been changed significantly (Hao et al., 2008;Ling et al., 2015;Ling et al., 2019;Ling et al., 2020;Xi et al., 2019;Fu et al., 2014;Deng et al., 2014;Ding et al., 2017;Xi et al., 2018). In the lower reaches of the Heihe River, Gobi and desert steppe have become the main landscape, and desert riparian forests comprise < 10% of the plant area (Cheng, 2009). ...
... Pearson's correlation coefficient (− 1.0 ≤ r ≤ 1.0) served to detect the correlation between two variables, where r > 0 indicates a positive correlation exists between the two variables, while r < 0 indicates an inverse relationship (Li et al., 2022). The Sen's slope method was adopted to investigate the temporal variation of NDVI, GPP, ET c act and WUE a.e. in this study (Yang et al., 2017). A 2-tailed hypothesis with p ≤ 0.05 indicated a significant test for Pearson's correlation and Sen's slope methods. ...
... This finding was consistent with similar machine-learning-based hydrological predictions at multiple time scales [67]. This was probably attributable to the decrease in the data characteristics for longer time steps [68]. Although the prediction performance deteriorated, the results of the BMA for the 2-and 3-month-ahead GWL predictions met the threshold of acceptable prediction requirements [59]. ...
... HR has been documented in more than 100 species [23], including agricultural crops and grasses [24][25][26], and forest trees and shrubs [27][28][29]. Although HR has been observed in diverse climatic settings [16,23,30,31], it is most prevalent in arid and semiarid ecosystems, such as savannas [16,32,33], arid climates and semideserts [5,[34][35][36], Mediterranean-type ecosystems [10,[37][38][39], and tropical forests [40][41][42]. However, HR may become increasingly relevant in temperate ecosystems that are subject to intensified drying-wetting cycles due to extreme drought events in projected climate-change scenarios [27,43]. ...
... Li et al. [29] discovered that the RH had the highest sensitivity, followed by T max , u 2 , SD and T min . She et al. [31] and Yang et al. [66] both indicated that the ET 0 was the most sensitive to R s , followed by RH and T a in parts of the Yellow River Basin. From the previous research above, the difference in sensitivity factors of ET 0 in different regions of China may have been mainly caused by the lower water vapor carried by the wind in dry regions and the higher humidity of the wind flow in humid regions [64]. ...
... [7][8][9][10][11] A large number of studies have applied bibliometric methods to identify research trends in various fields. 7,10,[12][13][14][15][16][17][18] Although a few articles related to hepatitis have been bibliometrically analyzed, 19 there is a lack of comprehensive bibliometrics for CHB treatment. The aims of this study were to apply bibliometric methods to identify specific areas of research activity concerning CHB treatment and to facilitate the identification of new areas for future development. ...
