【摘要】：利用2003-1~2013-12的GRACE月重力場(chǎng)數(shù)據(jù)來計(jì)算新疆天山地區(qū)陸地水儲(chǔ)量的變化,采用去相關(guān)濾波和300km高斯濾波相結(jié)合的方法來濾除GRACE數(shù)據(jù)中的噪聲,同時(shí)采用尺度因子的方法來減小GRACE后處理誤差的影響,并利用Paulson模型結(jié)果來扣除由冰川均衡調(diào)整(GIA)對(duì)水儲(chǔ)量反演結(jié)果的影響,把得到的最終結(jié)果與同期GLDAS、CPC水文模型進(jìn)行了驗(yàn)證分析。結(jié)果表明,GRACE反演結(jié)果與兩個(gè)水文模型的模擬結(jié)果變化趨勢(shì)基本一致,在2003~2013年間,研究區(qū)域的水儲(chǔ)量整體上呈現(xiàn)下降趨勢(shì),速率為-0.54±0.27mm/a左右,但期間水儲(chǔ)量變化波動(dòng)較大,在2008年10月份左右,該區(qū)域水儲(chǔ)量較同期呈現(xiàn)明顯減小,這與該時(shí)段的干旱事件相一致。
[Abstract]:The variation of land water reserves in Tianshan region of Xinjiang is calculated by using the monthly GRACE gravity field data from January 2003 to December 2013, and the noise from GRACE data is filtered by using the method of de-correlation filter and 300km Gao Si filter. At the same time, the method of scale factor is used to reduce the effect of GRACE post-processing error, and the effect of glacier equalization adjustment on water reserve inversion is deducted from the result of Paulson model. The final results are verified with the corresponding GLDASA CPC hydrological model. The results show that the GRACE inversion results are basically consistent with the simulation results of the two hydrological models, and the water reserves in the study area as a whole showed a downward trend during the period of 2003 / 2013. The rate is about -0.54 鹵0.27mm/a, but the water reserves fluctuate greatly during the period. In October 2008, the water reserves in the region decreased obviously compared with the same period, which is consistent with the drought events in this period.
