摘　　要：以银川平原典型区2018-2019年地下水埋深为研究对象,利用MK检验法和描述性统计分析对银川平原不同土地利用类型的地下水埋深进行分析。结果表明:裸地的地下水埋深均值最大,水稻田的均值最小;裸地和水稻田的地下水埋深为中等变异,林地和荒地为低等变异;水稻田在18年7月25日之前及18年8月20日之后呈上升趋势,埋深在19年7月5日发生突变,突变后减少了0.12m,其余未发生突变;裸地、荒地以及水稻田的地下水埋深规律主要受气象因素影响,林地主要受植被影响;地下水埋深极大值出现在傍晚的次数较多,埋深极小值出现在凌晨的次数较多。该结果可为银川平原土地利用等方面提供科学依据。Taking the groundwater depth of Yinchuan Plain from 2018 to 2019 as the research object,Mann-Kendall test and descriptive statistical analysis were used to analyze the groundwater depth of different land use types in Yinchuan Plain.The results showed that the average groundwater depth of bare land was the largest,and that of paddy field was the smallest;the groundwater depth of bare land and paddy field exhibited moderate variation,while that of woodland and wasteland exhibited low variation;the buried depth of paddy field showed an upward trend before July 25,2018,and after August 20,2018,and the burial depth changed abruptly on July 5,2019,and decreased by 0.12 m after the mutation,while no mutation occurred in the rest.The law of groundwater depth in bare land,wasteland,and paddy field was mainly affected by meteorological factors,and woodland was mainly affected by vegetation;the maximum value of groundwater depth appeared more in the evening and the minimum in the early morning.The results could provide a scientific basis for land use in Yinchuan Plain.
