| 摘 要： | 基于黑河沿岸地下水位观测井近20年实测观测资料,运用Mann-Kendall方法进行年地下水埋深序列的趋势分析,并选取代表观测井分析不同区域在不同时期内的年际与年内变化。结果表明:研究区地下水位埋深整体为增大趋势,区域地下水位下降趋势明显。年内的季节分配表明,从20世纪80年代至今,地下水位变化由水文-灌溉型逐步向开采型转变,其中平川区开采作用最为明显,集中表现在2000年之后,分水是导致这一时期地下水位下降的主要因素。

| Abstract: | Based on the observed data of groundwater monitoring wells during the past 20 years,using the method of Mann-Kendall to carry out trend analysis for the groundwater depth series,and selected the typical observed wells to analyze the change in year and years for different area and different periods.The results showed that: the regional groundwater level was evidently declining.From the 1980s to now,the type of dynamic change of groundwater level was gradually transformed from the hydrology-irrigation type to the exploitation type.The exploitation was enhanced.The most obuious area was Pingchuan Zone,especially after 2000.Water delivery to downstream was the main factor leading to the groundwater table decline. |
