Populus euphratica is the only dominant tree species of desert riparian forest in Tarim River Basin and faces a great threat drought. Policy-based artificial water delivery projects are an effective engineering method to mitigate drought reduce degradation forests. Forest gaps have been shown be primary mode regeneration. However, little known about growth status P. various arid zone habitats, particularly light complex diverse microenvironmental alterations understory. This study quantified effects flooded areas on changes The relationships between changes, soil physicochemical properties, physiological characteristics were investigated through cross-experiment that compared whether process was existed. results revealed gap increased diversity conditions ground; floods decreased temperature by 1.94 °C while they air humidity 8.19%. Flooding improved vertical distribution properties within also altering content indicators different directions. In research area, peroxidase activity (POD) exhibited significant differences (p < 0.05) understory euphratica, all after flooding. Changes microenvironments features together play important ecological role mitigating euphratica. These provide actionable theoretical basis for efficient management forests sustainable development zones.

The phenological characteristics of plants can reflect both their responses to environmental changes as well an ecosystem’s sensitivity climate change. Although there have been several studies plant species worldwide, is minimal research on the phenology vegetation found in extremely arid environments within context To address this gap, study investigated effects climate–hydrological factors, including temperature, precipitation, surface and humidity, (start growing season [SOS] end [EOS]) Populus euphratica Tarim Desert Oasis. Using Landsat 7/8 satellite imagery field data, we analyzed spatial temporal variations SOS EOS from 2004 2023. availability water, particularly groundwater depth directly played a key role shaping distribution dynamics P. phenology. impact increasing temperatures varied under different moisture conditions: high-moisture environments, increased promoted earlier delayed EOS, with opposite conditions occurring low-moisture environments. This highlights profound influence change, especially extreme regions. accurately predict response future ecological models should incorporate hydrological soil moisture, cold dry These findings provide important insights for developing effective protection management strategies.
