“…During 50 years of recovery, the speed of soil property recovery was faster during the early stages of recovery (1-15 years) and slower during the latter recovery stages (40-50 years). The C/N ratio showed the fastest rate of recovery (reaching 90% of the model curve asymptote value after 18 years) and soil bulk density was the slowest to recover (245 years) [24]. Soil moisture conditions needed at least 120 years to return to the shallow soil moisture conditions seen under natural vegetation.…”

“…As the BSC developed, the BSC and the underlying soil layers thickened, the soil bulk density decreased and the soil water-holding capacity increased. Therefore, the waterholding capacity of soils with different types of crusts was expected to increase in the following order: moss crusts > lichen crusts > algae crusts > cyanobacteria crusts [24]. The formation and development of BSCs also correlated with topography as the water holding capacity of the moss crusts that dominated the windward and hollow areas was significantly higher than that of the algae crusts, which mainly covered the leeward and crest areas [7,[21][22][23][25][26][27].…”

“…A decrease in soil property heterogeneity was an indication that the system was recovering, whereas increasing heterogeneity indicated that the system was degenerating [80]. This theoretical model explained the evolutionary mechanism behind the vegetation distribution over nearly 3 million ha desert areas in China and has important implications for vegetation construction and for the ecological management of the existing vegetation in desert regions [6,24].…”

“…For some soil properties, such as the percentage content of sand, silt and organic carbon, even if after a much longer period than 50 years, the model showed that they would still not reach the levels seen under the natural vegetation. These projected results indicated that once the soil habitat was destroyed, the ecological restoration of soil properties in arid desert regions was a very long process and very difficult and the decline in some soil properties was irreversible [6,24].…”

Soil water is the key abiotic limiting factor in desert areas and hydrological processes determine the vegetation composition, patterns and processes in desert regions. The hydrological processes can be altered by vegetation succession. In this paper, we review the major advances in ecohydrological research and their potential impact on plant-water relations in revegetated desert communities. The major advances in ecohydrological research over the past 50 years in desert areas were analyzed using a case study that investigated the long-term ecosystem effects of sand-binding vegetation in the Tengger Desert. Key challenges and opportunities for ecohydrology research in the future are also discussed in the context of the major scientific issues affecting sand binding vegetation.

“…Furthermore, the increased extraction of water from the deep soil layer (0.4-3.0 m), due to the development of shrub root systems and not enough water replenishment because of the infiltration reduction, both resulted in significant decreases in soil water content in the deep soil layer ( Figure 1B and C). The soil water-holding capacity increased as the BSCs developed and the topsoil layer thickened [18,30], which meant that the precipitation residence time was extended and soil water availability appreciably increased in the shallow soil layer. Thus, with the development of sand-binding vegetation, deep soil water decreased and the availability of shallow soil water increased.…”

The main prevention and control area for wind-blown sand hazards in northern China is about 320000 km 2 in size and includes sandlands to the east of the Helan Mountain and sandy deserts and desert-steppe transitional regions to the west of the Helan Mountain. Vegetation recovery and restoration is an important and effective approach for constraining wind-blown sand hazards in these areas. After more than 50 years of long-term ecological studies in the Shapotou region of the Tengger Desert, we found that revegetation changed the hydrological processes of the original sand dune system through the utilization and space-time redistribution of soil water. The spatiotemporal dynamics of soil water was significantly related to the dynamics of the replanted vegetation for a given regional precipitation condition. The long-term changes in hydrological processes in desert areas also drive replanted vegetation succession. The soil water carrying capacity of vegetation and the model for sand fixation by revegetation in aeolian desert areas where precipitation levels are less than 200 mm are also discussed. desert areas, sand fixation by plant, succession of the artificial vegetation, soil water dynamics, carrying capacity for vegetation Citation:Li XR, Zhang ZS, Tan HJ, Gao YH, Liu LC, Wang XP.

Soil respiration in water-limited ecosystems is affected intricately by soil water content (SWC), temperature, and soil properties. Eight sites on sand-fixed dunes that revegetated in different years since 1950s, with several topographical positions and various biological soil crusts (BSCs) and soil properties, were selected, as well as a moving sand dune (MSD) and a reference steppe in the Tengger Desert of China. Intact soil samples of 20 cm in depth were taken and incubated randomly at 12 levels of SWC (0 to 0.4 m 3 m À3 ) and at 9 levels of temperature (5 to 45°C) in a growth chamber; additionally, cryptogamic and microbial respirations (R M ) were measured. Total soil respiration (R T , including cryptogamic, microbial, and root respiration) was measured for 2 years at the MSD and five sites of sand-fixed dunes. The relationship between R M and SWC under the optimal SWC condition (0.25 m 3 m À3 ) is linear, as is the entire range of R T and SWC. The slope of linear function describes sensitivity of soil respiration to water (SRW) and reflects to soil water availability, which is related significantly to soil physical properties, BSCs, and soil chemical properties, in decreasing importance. Inversely, Q 10 for R M is related significantly to abovementioned factors in increasing importance. However, Q 10 for R T and respiration rate at 20°C are related significantly to soil texture and depth of BSCs and subsoil only. In conclusion, through affecting SRW, soil physical properties produce significant influences on soil respiration, especially for R T . This indicates that a definition of the biophysical meaning of SRW is necessary, considering the water-limited and coarse-textured soil in most desert ecosystems.
