| 英文摘要 | To evaluate the potential of soil water recovery after thinning, in situ soil water content in the 0-500 cm soil profile under thinned (50%-100%) and unthinned peashrub and alfalfa plots and a nearby natural grassland in the Liudaogou watershed in China's Loess Plateau (CLP) was measured monthly during 2015-2017 growing season using a neutron probe. At the start of experiment, the profile soil water storage (SWS0-500 cm) under introduced peashrub and alfalfa was, respectively, 18.8% and 12.2% lower than that under natural grassland. This showed that there was higher water consumption by planted vegetation, compared with native grass. After thinning, SWS0-500 cm in thinned peashrub and alfalfa plots was significantly higher than that in unthinned plots due to decrease in both interception and transpiration. The increase in SWS0-500 cm in the 100% thinned peashrub plot (159.9-216.1 mm) was much higher than that in 50% thinned peashrub (39.1-169.8 mm) and 100% thinned alfalfa (20.3-118.1 mm) plots. This indicated that the extent of soil water recovery varied with thinning intensity and vegetation type. At the end of the third growing season, soil water restoration frontier in the thinned peashrub and alfalfa plots (>300 cm) was much greater than that in the unthinned plots (<180 cm). It also indicated that with thinning, soil water (<300 cm) can recover rapidly following two successive wet years. The results suggested that concerns about soil desiccation and the potential impact on long-term sustainability of restored ecosystems on CLP were resolvable. |
