Due to the great influences of both climate warming and human activities, permafrost on Qinghai-Xizang Plateau (QXP) has been undergoing considerable degradation. Continuous degradation plateau dramatically modifies regional water cycle hydrological processes, affecting hydrogeological conditions, ground hydrothermal status in cold regions. Permafrost thawing impacts ecological environment, engineering facilities, carbon storage functions, releasing some major greenhouse gases exacerbating change. Despite utilization advanced research methodologies investigate changing processes corresponding influencing factors regions, there still exist knowledge gaps multivariate data, quantitative analysis degradation's impact various bodies, systematic modeling QXP. This review summarizes main methods hydrology elaborates precipitation distribution patterns, changes surface runoff, expansion thermokarst lakes/ponds, groundwater dynamics Then, we discuss current inadequacies future priorities, including multiple methods, observation spatial temporal scales, provide a reference for comprehensive environmental effects QXP under climate.

The transfer of water and energy fluxes between the ground atmosphere is influenced by soil moisture (SM), which an important factor in land surface dynamics. Accurate representation SM over permafrost-affected regions remains challenging. Leveraging blended from microwave satellites, this study examines potential for satellite assimilation to enhance LSM (Land Surface Model) seasonal Ensemble Kalman Filter (EnKF) used integrate data across Iya River Basin, Russia. Considering permafrost, only summer months (June August) are utilized assimilation. Field two sites validate study’s findings. Results show that lowers dry bias Noah up 6%, especially noticeable northern Basin. Comparison with situ station demonstrates a considerable improvement correlation after (0.94) before (0.84). findings also reveal significant relationship balance.

Abstract The Tibetan Plateau (TP) is the largest permafrost distribution zone at high‐altitude in mid‐latitude region. Climate change has caused significant degradation on TP, which important impacts for eco‐hydrological processes. In this study, frost number utilized to calculate ( F ) based air freezing/thawing index obtained from downscaled Coupled Model Intercomparison Project Phase 6 (CMIP6) data sets. A novel method proposed determine threshold t diagnosing distribution. Then simulated maps are compared with existing map, employing Kappa coefficient as measure of classification accuracy identify optimal . Finally, TP under different Shared Socio‐economic Pathways (SSP) scenarios diagnosed Simulation results demonstrate that across all scenarios, rates during mid‐future period (2040–2060) remain comparable those observed baseline (2000), ranging 33% ± 3% 53% 4%. Conversely, far‐future (2080–2099), display variation 37% 4% 96% 3%. profound reflected decreasing trends soil moisture and runoff, well a slower increasing trend Normalized Difference Vegetation Index (NDVI) other regions, indicating negative vegetation growth.

This study investigates relationship between permafrost runoff variations Source Region Yangtze River (SRYR), a critical tower supply Asia. We propose novel method assessing sensitivity, which establishes correlation changes hydrological responses, contributing to resource management. Our research quantifies key uncertainties change attribution, providing essential data decision making. Results show that watershed characteristics account up 20% variation, with (−0.02 sensitivity) demonstrating greater influence than NDVI variations. The findings offer insights development adaptation strategies, particularly maintaining ecosystem services ensuring long-term security under changing conditions. offers scientific basis climate-resilient management policies high-altitude regions.
