“…Empirical models are based on empirical relationships and have simple structures and few input variables (Davis, 1957;Francl & Panigrahi, 1997;Jacobs et al, 2002;Jia et al, 2019;Lekouch et al, 2012;, but these models have poor accuracy and are site-dependent. In contrast, physical models are based on physical mechanisms with high accuracy, but they are relatively complex and require multiple input variables (Beysens, 2006(Beysens, , 2016Madeira et al, 2002;Maestre-Valero et al, 2011).…”

“…Most prediction models for the amount and duration of dew were developed for and employed in humid regions (Beysens et al, 2005;Davis, 1957;Francl & Panigrahi, 1997;Gleason et al, 1994;Lhomme & Francisco Jimenez, 1992;Madeira et al, 2002;Maestre-Valero et al, 2011;Pedro & Gillespie, 1981a, 1981bRichards, 2009), but few studies have been conducted in arid and semi-arid regions (Beysens, 2016;Crowe et al, 1978;Gandhidasan & Abualhamayel, 2005), especially in deserts (Jacobs et al, 2002;Jia et al, 2019;Lekouch et al, 2012). Plausible reasons for this include: (a) Input variables, such as meteorological data near the study area, are not accessible or available; (b) the parameters of empirical models have high uncertainty and are difficult to control, meaning that they cannot be generalized to other regions unless first calibrated to local climate conditions (Beysens, 2016;Kidron, 1999); and (c) physical models cannot fully reflect the physical mechanism of dew formation due to intrinsic limitations.…”

As an important source of non-rainfall input of land-surface liquid water, dew has considerable ecological and hydrological significance in desert ecosystems. Dew moisture regime is commonly used for characterizing available dew. It discloses not only the contributions of dew to plants, small animals, and biological crusts but also the mechanism by which desert organisms adapt to extreme climates. By reviewing the existing researches on dew moisture regimes in desert ecosystems, this study reveals the variations in the amount and duration of dew, as well as its influencing factors at site-, catchment-, and regional scales, based on the radiation cooling theory and the physical mechanisms of dew formation. Furthermore, it compares the differences in dew moisture between various sites and catchments, illustrates the trends in daily and annual dew moisture in various deserts, and identifies the existing problems of researches on dew moisture regimes amid climate change. The findings of this study enhance preliminary knowledge on the reasonable utilization of dew water, worldwide.

“…Zhuang et al [60] reported that dew is a key source of water for sand-fixing plants in desert oases. Jia et al [61] stated that dew is a slightly stable water resource to maintain the biodiversity for the arid desert areas. Additional research suggests that dew is a stable and sustainable non-rainfall water supply to agriculture [62][63][64].…”

Soil moisture is the main limiting factor for crop growth and the sustainable development of oases in arid desert areas. Therefore, the temporal and spatial variation and infiltration laws of oasis soil moisture should be studied. The objective of this study is to reveal the influencing factors of the spatial-temporal variation of layered soil and sediment moisture and infiltration characteristics under irrigation in desert oases. Hydraulic conductivities were measured using the double-ring infiltrometer, while the regional and site soil moistures were measured and calibrated using weighted method and neutron moisture meter. Deterministic spatial interpolation methods, including multiquadric radial basis function, inverse distance weighted, and local polynomial regression isogram, were adopted to map the regional distribution of hydraulic conductivities, spatial soil moistures, and spatial-temporal isogram of the point site soil moistures in Yaoba Oasis, respectively. Results showed that the leading influencing factors of the (1) regional spatial soil moisture were soil and sediment permeability, stream link direction, microclimate, and dewfalls; (2) spatial layered soil and sediment moistures were microclimate and dew condensation; and (3) spatial-temporal variation at the point site profiles were soil texture, water requirement, and preferential flow. Under irrigation, soil moisture increased significantly, in which the maximum increase was 10.8 times the original state, while the recharging depth substantially increased up to 580 cm with the preferential flow. The spatial-temporal variation of the soil moisture under irrigation indicated that the best irrigation frequency should be 15 days per time. Moreover, the infiltration process can be divided into the preferential flow, piston flow, and balanced infiltration stages.

Mulched drip irrigation has been widely used in agricultural planting in arid and semi-arid regions. The dynamics and distribution of soil salinity under mulched drip irrigation greatly affect crop growth and yield. However, there are still different views on the distribution and dynamics of soil salinity under long-term mulched drip irrigation due to complex factors (climate, groundwater, irrigation, and soil). Therefore, the soil salinity of newly reclaimed salt wasteland was monitored for 9 years (2008–2016), and the effects of soil water on soil salinity distribution under mulched drip irrigation have also been explored. The results indicated that the soil salinity decreased sharply in 3–4 years of implementation of mulched drip irrigation, and then began to fluctuate to different degrees and showed slight re-accumulation. During the growth period, soil salinity was relatively high at pre-sowing, and after a period of decline soil salinity tends to increase in the late harvest period. The vertical distribution of soil texture had a significant effect on the distribution of soil salinity. Salt accumulated near the soil layer transiting from coarse soil to fine soil. After a single irrigation, the soil water content in the 30–70 cm layer under the cotton plant undergoes a ‘high–low–high’ change pattern, and the soil salt firstly moved to the deep layer (below 70 cm), and then showed upward migration tendency with the weakening of irrigation water infiltration. The results may contribute to the scientific extension of mulched drip irrigation and the farmland management under long-term mulched drip irrigation.
