摘　　要：洮儿河扇形地地下水位逐年下降,为了合理开发利用地下水,有必要对地下水动态特征进行分析。采用地下水动态分析、衬度系数方差分析以及相关分析三种方法对研究区地下水埋深进行分析。结果表明研究区内地下水埋深在2010年以前一直呈增大的趋势,2010年以后埋深呈现减小的趋势,地下水类型为渗入-径流型;研究区内地下水埋深波动变化较大,东北部的地下水波动程度明显大于其他区域,南部和西部也有部分波动性较大的区域;研究区总体上地下水埋深与降雨量的相关性较弱,其中研究区东部相关性要明显高于西部,只有部分区域呈现显著相关性。总的来说研究区东部地下水位动态的复杂程度要高于西部,并且总体上水位下降,需要及时采取措施,控制地下水的开采量,做到地表水与地下水联合调蓄,实现地下水资源的可持续利用。The groundwater table of Taoer river fan is declining year by year.In order to rationally develop and utilize groundwater,it is necessary to analyze the dynamic characteristics of groundwater.In this paper,three methods,including groundwater dynamic analysis,contrast coefficient of variance analysis and related analysis,are used to analyze the dynamical characteristics of groundwater in the study area.The results show that the embedded depth of groundwater in the area had shown an increase trend before the year of 2010,while it showed a decrease trend after 2010;the groundwater types is infiltration-radial flow type;the groundwater depth fluctuation in the study area is big,it is significantly greater in the northeast than in other areas;there are some volatile in south and west region,too.Overall,the correlation of groundwater depth to rainfall in the study area is weak,it is significantly higher in the eastern study area than in the western study area,and only some areas show significant correlation.Overall,the underground water level dynamic in the eastern study area is more complex than that in the west and the overall water levels is falling,so it is necessary to take timely measures to control the groundwater exploration,realize surface water and groundwater joint regulation and the sustainable utilization of groundwater resources.
