“…ET EC from the left bank side and the right bank side are put left and right in the brackets. Results of water budget (P-Q WS3 ) and ET by components sum (ET COMP, April 2007-March 2008Kumagai et al, 2014) energy imbalance correction made ET almost equal to P-Q (e.g., Ding et al, 2010;Barr et al, 2012). Meanwhile, Matsumoto et al (2011) obtained P, Q and ET EC_C for 8 years at their forest watershed in Japan, and they suggested that 5.6% of P would be lost as bedrock infiltration on average.…”

“…It is also central to the construction of an ecosystem-level water balance (Yang et al, 2009). Sap flow measurement can provide insights on environmental limitations and it yields results comparable with the estimates of water use for entire forest ecosystems (Chirino et al, 2011;Kumagai et al, 2014;Miyazawa et al, 2014). Previous studies have shown that sap flow characteristics vary with species and growth status, as well as with meteorological, environmental, and edaphic features (Brito et al, 2015;Du et al, 2011).…”

a b s t r a c tTerracing has long been considered one of the most effective measures for soil water conservation and site improvement. However, few studies regarding the quantitative effects of terracing on soil water dynamics and vegetation water use efficiency were reported. To fill these knowledge gaps, in this study, soil water content and canopy transpiration from 2014 to 2015 were monitored in both terrace and slope environments in the semiarid Loess Plateau of China. Results showed that terracing had positive influences on soil water content among layers. Mean soil water content of the terrace site was 25.4% and 13.7% higher than that in the slope site in 2014 and 2015, and canopy transpiration at the terrace site increased by 9.1% and 4.8%, respectively. Canopy conductance at the terrace site was 3.9% higher than that at the slope site and it decreased logarithmically with the increase of vapor pressure deficit. This study highlighted the critical role of terracing in soil-water improvement and water-stress mitigation in semiarid environments. Thus, terracing has the potential to enhance sustainable vegetation restoration in water-limited regions.

“…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).

“…tabulaeformis showed better growth (higher plant height, larger DBH, and greater crown area) than P. orientalis (Table 1), with a relatively lower SWC ( Figure 6). Differences in stand status and plant composition mainly affect the aspects of evapotranspiration (e.g., soil evaporation, T c , canopy interception), but not its magnitude (Chang et al, 2013;Granier et al, 2000;Kumagai et al, 2014).

Evaluating canopy transpiration and water use of two typical planted tree species in the dryland Loess Plateau of China

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.
