摘要
利用现状水质监测及灌区31 a的地下水动态观测资料,在系统研究灌区水文地质及环境条件的基础上,选取3个典型井进行地下水水质评价、水位动态及水化学特征要素的多年变化规律的分析;用matlab灰色预测法和SPSS计算软件对3个代表井的埋深和水质的变化趋势进行预测。可为水资源的合理配置、地下水适宜埋深及合理的施肥与灌溉方式的确定提供依据。
With the utilization of water quality monitoring and groundwater irrigation 31 years of observations,on the basis of hydro geological system of irrigation and environmental conditions,the paper selected three typical wells to carry out groundwater quality assessment,analysis of water level and water chemistry characteristics of the dynamic elements of change law for many years to fully explore the evolution of water dynamics and water quality of natural and man-made factors.It also predicted the depth and change trend of groundwater quality of 3 representative wells with the matlab gray prediction method and SPSS calculation software.The research results provide a basis for determining the rational allocation of water resources,suitable depth of groundwater,reasonable fertilization and irrigation.
