| 英文摘要 | Snow cover in the Himalayas plays a vital role in regulating elevation-dependent climate processes and sustaining downstream hydrology. However, its altitude-specific dynamics and implications for snow mass balance remain underexplored. Using the MOD09A1 dataset (2004-2024), this study conducts a pixel-based, elevation-stratified analysis with advanced spectral filtering and gap-filling techniques to enhance snow cover detection in complex terrain. The mean SCA was similar to 2.10 x 10(5) km(2), with sub-regional contributions from WH: 8.59 x 10(4) km(2), CH: 9.55 x 10(4) km(2), and EH: 2.99 x 10(4) km(2), indicating distinct spatiotemporal variability. Correlation analysis revealed that SCA in WH and CH is mainly precipitation-driven (r = +0.70 and r = +0.91), whereas EH is temperature-dominant (r = -0.65), reflecting strong climatic control. Altitudinal and zonal snow cover changes were assessed using Equilibrium Line Altitude-AAR and AABR methods for mass balance estimation. Regional trends showed a positive mass balance of 0.0389 at 4105 m in WH, with increasing SCA around 4516.12 +/- 531.94 m; CH exhibited a negative balance (-0.0268 at 4989 m), with declines at higher altitudes; and EH demonstrated a negative balance (-0.015 at 4378 m), with notable SCA reduction. Mann-Kendall and Kendall Tau tests validated these trends, highlighting spatially heterogeneous snow-cover dynamics and their implications for Himalayan snow-mass balance. |
