Impact of rainfall on root water uptake in two characteristic species of coal mining subsidence areas in Northwest China.

ABSTRACT: Clarifying how plants utilize water in coal mining subsidence zones is essential for grasping plant-soil dynamics and guiding ecological rehabilitation. However, current knowledge on species-specific variations in water uptake and their adaptive responses to such subsidence remains limited. This research leveraged isotopic fingerprinting (δ ² H, δ ¹⁸ O) alongside soil water content and root distribution to explore the root water uptake sources of two predominant species (Stipa bungeana Trin. and Artemisia desertorum Spreng.) in coal mining zones and their reactions to land subsidence triggered by coal extraction. The results indicated negligible differences in soil water content and soil water isotopic composition between subs
