摘要

摘要: 引黄水量是银川平原地下水的重要补给来源,为了分析银川平原地下水位对黄河水量统一调度的响应,采用趋势分析、R/S分析及Arc GIS地理空间分析等方法,解析1995-2019年银川平原地下水埋深的时空变化特征,并以黄河水量统一调度后的引黄水量变化为主,对影响地下水位变化的主要影响因素进行了甄别。结果表明:银川平原地下水埋深在2001-2019年呈现明显的增加趋势,由2001年的1.4 m增加到2019年的2.3 m;采用R/S分析法计算地下水埋深月平均值时间序列的Hurst指数为0.78,表明地下水埋深动态序列具有持续性;空间上以银川市和石嘴山市为中心,地下水埋深不断增大,其中又以银川市地下水埋深增加幅度最大; 2001-2019年的地下水年均埋深与引黄水量间呈显著相关,引黄水量的减少是导致地下水埋深增加的主要原因。研究厘清了银川平原地下水埋深与引黄水量间的关系,为践行黄河流域生态保护与高质量发展提供科学依据。

Abstract: The water diverted from the Yellow River is an important replenishment source for the groundwater in Yinchuan Plain. In order to analyze the response of Yinchuan Plain groundwater depth to the integrated water regulation of the Yellow River,methods such as trend analysis,R/S analysis and ArcGIS geographic spatial analysis were used to analyze the temporal and spatial variation characteristics of the groundwater depth in Yinchuan Plain from 1995 to 2019 and its main influencing factors were screened with the emphasis on the volume change of the water diversion after the implementation of the integrated water regulation of the Yellow River policy. The results show that the groundwater depth of Yinchuan Plain increased significantly from 2001 to 2019,it increased from 1. 4 m in 2001 to 2. 3 m in 2019. The Hurst index of the monthly average time series of groundwater depth calculated by R/S analysis method was 0. 78,indicating that the dynamic series of groundwater depth was continuous. The depth of groundwater had been increasing spatially centered on Yinchuan and Shizuishan City,with the largest increase in Yinchuan City. The average annual groundwater depth of 2001-2019 was significantly correlated to the amount of water diversion from the Yellow River,and the decrease in the water diversion was the main reason for the increase in the groundwater depth. The study clarified the relationship between the depth of groundwater in Yinchuan Plain and the amount of water diversion from the Yellow River,providing a theoretical support for the promotion of ecological conservation and high-quality development of the Yellow River Basin.
