摘要

利用2003年1月至2012年12月120个月的GRACE数据,基于高斯平滑和平滑滤波手段,辅以TRMM降水量、河网分布、蒸散发、径流等数据,反演了新疆陆地水储量,分析了10年间陆地水储量的时空变化情况.结果表明:2003—2012年新疆地区陆地水储量持续减少,但后半期水储量的减幅有所减缓;陆地水储量具有明显降低趋势的地区范围逐步向新疆东部迁移,水储量具有上升趋势的面积有逐渐增加的倾向,但是这种显著上升趋势所涵盖的面积没有占据研究区的主导地位;GRACE的年周期值和陆地水储量深度值的波动趋势一致;TRMM降水变化趋势与GRACE反演的陆地水变化趋势相辅相成,相互验证.该项研究可为新疆合理用水及缺水地区水资源合理的开发等提供理论依据.

Abstract

In this study, the water reserves over Xinjiang was inversed based on 120-monthes GRACE data from January 2003 to December 2012. Gaussian smoothing and smoothing filtering method were used to analysis the temporal and spatial changes of water storage and its trend during the 10 years, with the TRMM data as auxiliary data. The conclusions as below: the water storage is keeping decreasing during these 10 years, but the decreasing rate of water storage during the later five years is smaller than the previous five years. The area that with a significantly decrease trend of water storage is migrating to the east part of Xinjiang gradually; the area that with an increasing trend is getting lager, but the increasing trend is not the leading role. The fluctuations of the GRACE year annual cycle values and the water thickness inverse are identical. The change of water reserve inversed with GRACE data is parallel with the TRMM precipitation trend. This study provides a reliable theoretical basis for the rational use of water in Xinjiang, as well as rational development of water resources in water-scarce regions.
