摘要
介绍了基于质量负荷理论利用GNSS观测反演陆地水储量的方法,阐述了利用GNSS研究陆地水储量的进展、应用和发展趋势,以及GNSS与GRACE、水文模型等的联合研究。随着GNSS观测精度的不断提升和观测网络的迅猛发展,利用GNSS观测研究陆地水储量取得了重要进展。GNSS已成为陆地水储量监测的重要手段,在中国大陆地区利用GNSS研究陆地水储量具有巨大的潜力和前景,但仍需要在时间序列信号精细识别、反演算法优化和多源数据融合等方面深入研究。
The method of inversion of terrestrial water storage using GNSS observation based on mass-loading theory is introduced,and the progress,application and development trend of using GNSS to study terrestrial water storage,as well as the joint research of GNSS with GRACE and hydrological models are described.With the continuous improvement in the accuracy of GNSS observation and the rapid development of observational network,remarkable advances have been made in the study of terrestrial water storage by GNSS observation,and GNSS has become an important means of terrestrial water storage monitoring,and the use of GNSS to study terrestrial water storage in Chinese mainland has great potential and prospect.But it still needs to be further researched in the aspects of fine identification of time series signals,optimization of inversion algorithms,and fusion of multi-source data.
