“…Thus, the water samples were collected after each rainfall event during the growth season from 13 August 2015 to 29 July 2016, and samples were not collected during the frozen season (November 2015 to March 2016). Torstenw and Li’s methods were used to collect the precipitation, throughfall and stemflow data, and the details are as follows 32,44 :Precipitation: the rainfall was sampled in the non-forest site with 5 homemade continuous rain gauges (surface collection area of 0.64 m 2 ).Throughfall: the throughfall was recorded using 5 PVC rectangle grooves (surface collection area of 400 cm × 16 cm) in the 3 plots, and 5 gutters were set up 1 m above the floor to avoid ground splash effects. Furthermore, the gutters were also set up at a 5° angle to horizontal to promote drainage, and the lower end of each gutter was equipped with a plastic bucket.…”

Canopy exchange is one of the most important processes involved in the internal transfer of elements in forest ecosystems. However, little information is available on how canopy exchange influences the input of base cations in subalpine forests. Therefore, the concentrations and fluxes of base cations in throughfall and stemflow were investigated from August 2015 to July 2016 (except for the frozen season) in a representative subalpine spruce plantation in the eastern Tibet Plateau. Our results showed that the mean concentrations of K, Ca, Na and Mg were higher in the stemflow than in the throughfall and precipitation. The total input fluxes of K, Ca, Na and Mg in the internal forest were lower than those in the non-forest. Moreover, the results from the canopy budget model indicated that the canopy exchange fluxes of K, Ca and Mg were higher than the dry deposition fluxes, and Ca and Mg were uptaken, whereas K was leached when precipitation passed through the canopy. Therefore, the results suggested that the input of base cations is mainly controlled by canopy exchange during precipitation in subalpine forest ecosystems, and the canopy could alter the sinks and sources of base cations from precipitation.

“…Raz-Yaseef, Rotenberg, and Yakir (2010) reported that mean soil evaporation measured in sun-exposed areas was double than that of shaded areas. Canopy interception can account for 10-40% of annual evapotranspiration (Chang et al, 2013;Raz-Yaseef et al, 2010), an amount that varied with canopy density (Kumagai et al, 2014), rainfall intensity (Fang, Zhao, Jian, & Kai, 2013), and precipitation type (Li, Cai, Man, Sheng, & Ju, 2015). Canopy interception can account for 10-40% of annual evapotranspiration (Chang et al, 2013;Raz-Yaseef et al, 2010), an amount that varied with canopy density (Kumagai et al, 2014), rainfall intensity (Fang, Zhao, Jian, & Kai, 2013), and precipitation type (Li, Cai, Man, Sheng, & Ju, 2015).…”

“…Greater canopy coverage also increased intercepted water loss. Canopy interception can account for 10-40% of annual evapotranspiration (Chang et al, 2013;Raz-Yaseef et al, 2010), an amount that varied with canopy density (Kumagai et al, 2014), rainfall intensity (Fang, Zhao, Jian, & Kai, 2013), and precipitation type (Li, Cai, Man, Sheng, & Ju, 2015). Large evapotranspiration values, combined with low levels of soil water infiltration, could cause severe soil desiccation.…”

Large-scale vegetation restoration has been conducted in China's Loess Plateau over the past several decades to control soil and water loss. However, these efforts have not followed any specific guidelines to select plant species that balance the twin goals of vegetation restoration and water demand. In the present study, we measured canopy transpiration characteristics of oriental arborvitae (Platycladus orientalis) and Chinese pine (Pinus tabulaeformis), two species that are commonly planted in restoration efforts, and recorded water input and output for these two species during the growing season. P. tabulaeformis had a higher tolerance than P. orientalis to warmer and drier environments and used water over a wider time span. Canopy transpiration significantly increased when rainfall exceeded 15 mm and was negatively correlated with net change of soil water content. Meanwhile, rainless intervals also affected canopy transpiration recovery. Canopy transpiration of P. tabulaeformis was 25.4% higher than that of P. orientalis. Soil water content under P. orientalis declined by 28.4% after the growing season, while it slightly increased under P. tabulaeformis (0.7%). Our results suggested that although P. tabulaeformis plantation had higher canopy transpiration, this water use did not drastically reduce soil water content, mainly due to the lower evaporation caused by the dense canopy cover. However, the low soil water content also implied that a better management, such as a mixed plantation of these two species and other supplemental water-conservation techniques, should be considered to better use water in this semiarid region.

“…It has been shown there is a significant effect in vegetation restoration in semiarid areas since the afforestation projects were implemented (Hou, Li, Wang, & Zhang, 2016), afforestation benefits carbon sequestration through the accumulation of aboveground and belowground biomass (Li et al, 2012). The Pinus sylvestris planted forest, as an evergreen, cold‐resistant, and drought‐tolerant tree species, plays a key role in desertification control (Li, Cai, Man, Sheng, & Ju, 2015; Song, Zhu, Li, Zhang, & Lv, 2016) in arid and semiarid desert regions of northern China. Planting P. sylvestris is beneficial for increasing soil carbon storage (Gao & Huang, 2020).…”

The carbon pool is changing in afforestation ecosystems, which vary in their duration since establishment, in many semiarid sand regions. Understanding this is important for the management of the planted forest. The present study explored the dynamics of afforested forest carbon pool in a semiarid sandy ecosystem, northwest China. We studied afforested forests of pine (Pinus sylvestris) of five afforestation ages (20, 30, 40, 50, and 60 years since planting, and bare sand as control), the carbon storage and carbon sequestration rate of the forest aboveground biomass layer, surface litter layer, and soil layer (0-50 cm) were calculated, and the soil water content and soil organic carbon of 0-400 cm soil depth were measured. The results showed that the carbon sequestration rate was highest after 20-30 years, with 0.58 Mg C ha −1 yr −1 in the soil layer (0-50 cm). We found a rate of 0.13 Mg C ha −1 yr −1 in the surface litter layer, and a rate of 20.79 Mg C ha −1 yr −1 in the forest aboveground biomass layer. The carbon storage of the forest aboveground biomass layer was highest after 30-40 years, and the carbon storage of the surface litter increased with time. In the soil layer, the carbon storage at 0-10 cm depth was highest after 60 years, the carbon storage at 20-50 cm depth increased soon after afforestation and then decreased afterward with increasing afforestation ages with the maximum for 20-50 cm occurring after 30-40 years. The total carbon storage [the forest aboveground biomass layer, surface litter layer and soil layer (0-50 cm)] was higher when afforestation ages reached around 30 years, after that it decreased with increasing afforestation age. Our research improves the understanding of the P. sylvestris forest ecosystem carbon sequestration in a semiarid sandy area.
