摘要
研究了建三江分局地区地下水动态特征,确定研究区地下水动态类型属于水文-开采型,年内动态随地下水开采时间和强度而变化,地下水水位呈逐年下降趋势。区内监测井埋深序列的衬度系数方差呈现西南部大于东北部的趋势,分形分析结果也表明,区内西南部的分形维普遍大于东北部。研究区西南区域地下水的年内动态变化要强于东北区域,地下水位年际下降趋势的幅度也要大于东北区域。
Dynamical characteristics of groundwater dynamic in Jiansanjiang area are studied in this paper. The result shows that the groundwater dynamic is exploit-hydrological type and the dynamic during a year change along with the time and intensity of groundwater exploitation; the groundwater level in the studying region is declining year by year. Variances of contrast coefficients of time series of groundwater buried depth in southwest are larger than that in northeast. Analogously, fractal dimensions in southwest are generally higher than that in northeast from the conclusion of fractal analysis. The dynamic changes of groundwater during a year in southwest of Jiansanjiang area are bigger than that in northwest, as well as the amplitude of interannual downward of the groundwater level.
