摘要: 区域水储量变化同时受多个水文气象要素影响. 采用2003年1月至2013年11月GRACE重力卫星的UTCSR-RL05L-2月数据, 对比分析了近11a新疆天山中段南北坡水储量时空变化特征及影响因素, 并用GLDAS模型模拟结果进行验证. 研究结果表明: (1)每年5~9月是天山中段水储量的消耗期, 11月至翌年3月是水储量的积累期, 北坡水储量的变幅大于南坡. (2)近11a南北坡水储量均呈现增加趋势, 北坡水储量增加幅度较大, 其年周期的起始时间也较南坡早14d. (3)在影响南北坡水储量的众多因素中, 冬季水储量受降水影响较大, 夏季水储量受蒸发影响较大, 而雪水当量变化则在冬春季节对水储量产生一定影响, 但春季具有延迟性. (4)北坡水储量与降水蒸发差的一致性较好, 而南坡相对较差.

Abstract: The change of water storage in a region is influenced by various hydro-meteorological factors. This paper applied the UTCSR-RL05 L-2 data, from January 2003 to November 2013, to investigate the temporal and spatial changes of water storage in the north and south slopes of the central Tianshan Mountains in Xinjiang, China. The water storage changes based on GLDAS model data are used to test GRACE data. The results show as follows: (1)The water storage decreases in the Central Tianshan Mountains from May to September and increases from November to March of the next year. The water storage change range of the north slope is larger than that of the south slope.(2)The water storage changes in both of the north and south slopes show increasing trends in recent 11 years, while the increasing range is greater in the north slope. The start time of annual cycle of water storage change in the north slope is 14 days earlier than that in the south slope.(3)The water storage change in the north and south slopes is mainly affected by precipitation in winter and by evaporation in summer. The water equivalent of snow has some impact on water storage changes in winter and spring. The effect has a time delay in spring.(4)The difference between the precipitation and the evaporation is consistent with the water storage changes in the north slopes, but the consistency in the south slopes is not as good as that in the north slopes.

Key words: water storage changes, the central Tianshan Mountains, contrast of the north slopes and the south slopes, the temporal and spatial changes, influencing factors
