气候变化和人类活动对西辽河流域陆地水储量变化的影响
Impact of Climate Change and Human Activities on Water Storage Variability in the West Liaohe River Basin
摘要
Abstract
In order to investigate the variations in terrestrial water storage(TWS)and their driving factors in the West Liaohe River Basin,this study employed a Long Short-Term Memory(LSTM)model to reconstruct missing data between the GRACE and GRACE-FO satellite missions from April 2002 to December 2020.The water balance approach was utilized to analyze the spatiotemporal characteristics of TWS changes,and a quantitative assessment was conducted to evaluate the relative contributions of climate change and anthropogenic activities.The findings reveal that:a)The LSTM model effectively reconstructs the missing TWS data between the GRACE and GRACE-FO satellite re-cords,demonstrating its applicability in hydrological studies.b)During the study period,GRACE-based observations indicate a significant decline in TWS in the West Liaohe River Basin at a rate of 0.41 mm/month,with pronounced spatial heterogeneity,particularly severe deple-tion in the southern region.c)Anthropogenic water consumption exerts a considerable influence on TWS variations,whereas the impact of reservoir storage is relatively limited;climate change emerges as a key determinant of TWS fluctuations.关键词
