Abstract The intensification of the global hydrological cycle is anticipated to increase variability precipitation patterns. Brackish wetlands respond changes in patterns by regulating absorption and release CO 2 H O maintain stability ecosystem functions. However, there limited understanding how inter‐seasonal distribution (SPD) affects exchange compared with annual totals. Here, we conducted four consecutive years field experiments a brackish wetland, manipulating proportion across different seasons while maintaining constant total. We utilized five inter‐SPD proportions (+73%, +56%, control (CK), −56%, −73%) examine effects SPD on exchange. Our findings revealed that fluxes showed trend decreasing decrease spring distribution. Among them, net exchange, evapotranspiration, carbon use efficiency water were shown be more sensitive summer autumn This negative asymmetric response pattern suggests primarily governed seasonal variability, soil water–salt dynamics identified as key driver. Therefore, this association can explained fact drought early growth stage exacerbates salinization inhibits vegetation colonization growth, thereby greatly impairing –H capacity wetlands. results emphasized extreme precipitation‐induced conditions will influence future.

Ecological sustainability quantifies the capacity of an ecological system to sustain its health while fulfilling human survival needs and supporting future development. An accurate projection dynamics for is crucial decision-makers comprehend potential risks. However, intricate interplay between climate change activity has hindered comprehensive assessments sustainability, leaving it inadequately investigated thus far. This study aimed assess shaped by Shared Socioeconomic Pathways (SSPs) using remote sensing data from a typical arid farming–pastoral zone located at northern foot Yinshan Mountain (NFYM), Inner Mongolia, China. Five machine learning models were employed evaluate relationship driving factors. The results indicate that (1) overall initially decreased then increased during 2003–2022; (2) Geophysical Fluid Dynamics Laboratory Earth System Model version 4 (GFDL-ESM4) mode random forest model demonstrated best performance in simulations; (3) annual rates 2023 2099 are projected be +0.45%, −0.05%, −0.46% per year under SSP1-2.6, SSP2-4.5, SSP5-8.5 scenarios, respectively, suggesting stringent environmental policies can effectively enhance sustainability. proposed framework assist understanding changes different SSPs calls strategies ecosystem resilience NFYM similar regions.

Abstract Physiological drought stresses induced by high salinity and atmospheric dryness exert negative effects on mangrove growth constraining surface conductance (Gs) evapotranspiration (ET). However, accurate assessments of vulnerability under changing climate are hindered limited understanding the relative importance these stresses.
