|
摘要
[目的]研究科尔沁沙地水储量变化对该区域的生态环境和经济建设等的影响,为当地水资源的保护和可持续利用提供参考。[方法]利用CSR(center for space research)提供的2003.07～2010.12 GRACE(gravity recovery and climate experiment)Release-05数据,采用去相关与高斯平滑滤波(平滑半径300 km)相结合的滤波方法,以及尺度因子法进行了重力信号改正和信号泄露恢复,反演了科尔沁沙地陆地水储量长时间序列的变化,该结果与CPC(climate prediction center)水文模型反演结果进行了对比分析;结合GLDAS(global land data assimilation system)水文模型计算的土壤含水量变化,给出了科尔沁沙地地下水储量的时空变化;并利用监测点水井数据和给水度信息对地下水反演结果进行了初步验证。[结果] 2003年7月至2010年12月科尔沁沙地陆地水储量减少速率为-13.2±2.6 mm/a;地下水下降速率为-13.5±1.9 mm/a。[结论]干旱和农业灌溉是导致科尔沁沙地地表水减少和地下水位降低的重要原因之一。
[Objective] The impact of water storage variation on the local ecological environment and economic construction in the Horqin sandy land was studied in order to provide reference for the protection and sustainable utilization of local water resources. [Methods] Using gravity recovery and climate experiment(GRACE) Release-05 data from July 2003 to December 2010 provided by center for space research(CSR), the long-time series of terrestrial water reserves in Horqin sandy land were retrieved by using the filtering method combining the decorrelation filter with the Gauss smoothing filter(smooth radius 300) and the scaling factor method. The result was compared with the Climate Prediction Center(CPC) hydrological model inversion. Based on soil moisture content changes calculated by GLDAS hydrological model, the temporal and spatial variation of ground water storage was retrieved. This result was preliminarily verified by monitoring well data and feed water information. [Results] The reduction rates of terrestrial water storage and ground water storage were 13.2±2.6 and 13.5±1.9 mm/a, respectively from July 2003 to Decomber 2010. [Conclusion] Drought and agricultural irrigation are one of the important reasons leading to the decrease of surface water and groundwater level in Horqin sandy land.
