摘  要:
【目的】研究伊犁河流域地下水含盐量的时空变异特征。【方法】以新疆伊犁河流域察布查尔县为例,基于现阶段地下水研究成果,利用2009年的地下水采样数据,应用surfer7.0及arcgis9.2等软件进行分析。【结果】研究区2009年3、6月地下水含盐量对数转换后符合正态分布,变异函数曲线理论模型均符合球状模型。【结论】在时间上,6月与3月相比地下水含盐量数据变异性较小,地下水含盐量整体上呈现上升,但含盐量较大区域出现下降。在空间上,研究区周围区域的地下水含盐量数据变异较小,并出现了地下水含盐量较高区域逐渐向外围减小的现象。

摘  要:
[Objective]this study aims to search for space-time character of salt contont in underground water of Ili Rivet valley.[Method] Based on the current study achievements about groundwater,the water sample data collected from Ili River Valley in 2009,applying surfer 7.0 and aregis 9.2 were andyzed.[Result]The converted logarithm of salt contcnt in groundwater conforms with normal dislribution.The model of variance function curve theory conforms with the globular one in Mar.and Jun.2009in study area.[Conclusion]The result reveal that the variation of groundwater salt content is comparatively small,by comparing Jun.with Mar.groundwater salt content is increased in the general,but the salt content in the some areas with great amoant of it in the riginal period becomes comparatively low.Tthe variation of groundwater salt content is comparatively smaller in surrounding area,and the groundwater content s comparatively from high to low gradually decrease from center to periphery.
