洛惠渠灌区地下水盐动态规律研究
Journal Title: Science Paper Online - Year 2007, Vol 2, Issue 2
Abstract
深入了解地下水盐动态规律是解决土壤盐渍化和地下水污染等问题的基本理论之一。本研究根据洛惠渠灌区地质地貌，将整个灌区划分为三层阶地，在2005年对三层阶地上的地下水盐动态进行实时监测，将采集到的数据运用双因子方差分析方法，详细论述了地下水电导率随地下水位不同时期及不同分布条件下变化情况。结果表明，地下水电导率变化与水位变化有很大关系，且表现出很强的区域特征：各阶地EC值均随水位的上升而增加，高EC值出现在高水位区，第一阶地高水位电导率存在显著变异。另外微地域环境、气候、生物、人类活动等外界因素也会影响地下水盐的动态过程。因此，有效降低该灌区地下水位是控制土壤盐化的重要措施，实现农业可持续发展的关键所在。
