摘要

摘要智利水资源分布不均，水位站有限，地质条件易发地震，难以准确、全面地监测智利陆地蓄水量的变化。重力恢复和气候实验（GRACE）已被广泛用于估计TWS的变化。本研究使用GRACE解和消除地震影响的方法来估计TWS的变化。扣除地震影响后的估算结果表明，智利TWS变化率总体呈−0.16±0.096 cm年−1的下降趋势。此外，在目标期内，降水量主要减少，蒸散量增加。TWS变化、降水量和蒸散量之间的相关系数小于0.4，表明TWS中的因素更为复杂。智利的气温也呈现出每年0.06°C的上升趋势。这些信息将有助于了解智利TWS变化的特征及其对气候变化的反应。

Estimating terrestrial water storage variations in Chile with the effects of earthquakes deducted

ABSTRACT Chile has unevenly distributed water resources, limited water level stations and earthquake-prone geological conditions, making it difficult to accurately and comprehensively monitor Chile’s terrestrial water storage (TWS) variations. The Gravity Recovery and Climate Experiment (GRACE) has been widely used to estimate TWS variations. This study uses GRACE solutions and a method of eliminating earthquake effects to estimate TWS variations. The estimation results with earthquake effects deducted show that the rate of TWS variation in Chile is generally a decreasing trend of −0.16 ± 0.096 cm year−1. Furthermore, in the target period, precipitation mainly decreased and evapotranspiration increased. Correlation coefficients between TWS variations, precipitation and evapotranspiration are less than 0.4, suggesting that the factors in TWS are more complex. Temperature also shows an increasing trend of 0.06°C year−1 in Chile. This information will help to understand the characteristics of the TWS variation in Chile and its response to climate change.
