The absorption of atmospheric water by plants through their leaves, known as leaf uptake, plays a crucial role in sustaining plant growth and survival arid regions. Condensate is one the important sources for zones an alleviating physiological state water. In order to clarify ecological condensation water, we took dominant species desert Dugay forest plant, Populus euphratica, research object, based on situ humidification field experiments, comprehensively analyzed effect P. euphratica benefit zone determining parameters indexes leaf, wettability, water-absorbing capacity leaf. results showed that leaves have ability both sides, under treatment, potential dawn TR group (−1.75 ± 0.12 MPa) was significantly higher than CK (−1.41 0.13 Mpa); net photosynthetic rate (13.08 0.68 μmol·m−2·s−1) (10.42 0.57 μmol·m−2·s−1); proline content (22.82 0.8 μg·g−1) lower (68.67 6.14 μg·g−1); capacity, osmotic adjustment, stress tolerance affected were different (p < 0.05). A leaf’s mainly content, other influencing factors. mean FWU positively correlated with transpiration rate. Within Ebinur Lake watershed, accounts 10.92% maximum (Tr); 2022, total summer surface uptake about 220.5 mol, value represents 0.25% average annual evapotranspiration from Lake. This study helps improve understanding impact ecology provides scientific basis benefits
