摘要
泾惠渠灌区是陕西重要的农业生产基地,研究灌区干旱时段的地下水动态对灌区农业生产具有重要意义。通过灌区多年的降水量资料,采用Z指数法选取了灌区的典型干旱时段,然后选取灌区内的典型观测井位分析了其干旱时段内地下水动态特征。
Jinghuiqu irrigation area is a major agriculture production base in shanxi province.There is great significant to study on irrigation area＇s groundwater dynamics of arid period for agricultural activities.We select the typical arid period through Z index method using years of precipitation data of the irrigation area,and we analyze the dynamics characteristic of groundwater through several typical observation wells in the irrigation area.
