| 摘 要： | 该研究基于2004-2013年对新疆希尼尔水库灌区13个观测井地下水埋深的长序列监测结果,利用相对差分法、Spearman秩相关系数法和Morlet小波变换的方法分析了研究区地下水埋深的时间稳定性和周期性特征.结果表明:在不同监测时间的地下水埋深均属于中等变异,变异系数的范围为44%~75%.地下水埋深表现出强烈的时间稳定性;小波分析表明研究区地下水埋深存在周期性变化.研究结果为灌区合理开发利用地下水资源以降低土壤盐渍化风险提供了一定的参考.

| Abstract: | The research is based on long series monitoring results of 13 observation well groundwater buried depth in Xinjiang Xinier Reservoir irrigation district from 2004 to 2013.Relative difference method, Spearman rank correlation coefficient method and Morlet wavelet transform method are utilized to analyze the time stability and periodic characteristics of groundwater buried depth in the study area.The results show that the buried depth of groundwater in different monitoring time belongs to medium variation.The range of variation coefficient is 44%~75%.Groundwater buried depth shows strong time stability.Wavelet analysis shows that the embedded depth of groundwater in the study area has cyclical change.The results of the study provide certain reference for reasonable exploitation and utilization of groundwater resources and reduce soil salinization risk in the irrigation district. |
