Determination of the Ecological Groundwater Depth Considering Ecological Integrity over Oasis Irrigation Areas in the Yanqi Basin
焉耆盆地绿洲灌区生态安全下的地下水埋深合理界定

In arid areas, the buried depth of groundwater and salt content jointly affect the growth of natural vegetation. Salts dissolved in groundwater can be carried upward by capillary water and accumulated in top soil if the groundwater buried depth is too shallow under violent evaporation conditions. As such, soil salinization and salt stress often occur. Upward capillary water cannot reach the rhizosphere of plants if the groundwater buried depth is too deep. Therefore, the growth of vegetation is in part dete...
