【目的】研究新疆塔里木盆地灌区地下水水质空间变化及影响因素。【方法】依据1 292组地下水水质检测资料,通过描述性统计分析方法和Piper三线图解法分析地下水化学组分特征及水化学类型,采用水质指数法、USSL图和Wilcox图解法对灌区地下水水质进行了评价,运用克里金插值法、因子分析和离子比值等方法对灌区地下水水质空间变化及其影响因素进行了分析。【结果】山前砾质倾斜平原区地下水质量优于中下游的细土平原区,地下水从山前砾质倾斜平原区流动到细土平原区的过程中,经过岩石的溶滤作用,致使地下水中离子量增多,水质逐渐趋于劣化。灌区地下水可溶性盐浓度过高,通过强烈的蒸发作用使埋藏较浅的地下水中的盐类离子析出,使得盐分积聚地表,会加重土壤盐渍化;灌区地下水水质优劣排序为:单一结构潜水>承压水>承压水区潜水...
