Sequencing data of microorganisms from water level tests

Currently, drought events caused by climate change and human activities have made the ecological conservation of wetlands an increasingly serious challenge. However, the adverse effects of drought stress on marsh wetland health, particularly the microbial-driven mechanisms of changes in wetland material cycling, are not yet systematically understood. To address this issue, a water level control experiment has been carried out in selected typical wetlands in northeast China since 2018. Changes in wetland ecological functions were studied by long-term automatic control of four different water levels: L1 (severe drought, 20 cm below average), L2 (mild drought, 10 cm below average), L3 (control, at average level), and L4 (inundation, 10 cm above average).
