Linking Populus euphratica Hydraulic Redistribution to Diversity Assembly in the Arid Desert Zone of Xinjiang, China
The hydraulic redistribution (HR) of deep-rooted plants significantly improves the survival of shallow-rooted shrubs and herbs in arid deserts, which subsequently maintain species diversity. This study was conducted in the Ebinur desert located in the western margin of the Gurbantonggut Desert. Isotope tracing, community investigation and comparison analysis were employed to validate the HR of ...
متن کاملHow to Regenerate and Protect Desert Riparian Populus euphratica Forest in Arid Areas
We found that the most suitable flooding disturbance model for regenerating Populus euphratica forest was two to three times per year with a duration of 15-20 days and an intensity of 25-30 m(3)/s. The flooding should take place during the seed emergence to young tree growth stages, and should be based on flooding experiments and data from vegetation quadrats and ecological water conveyance. Fu...
