Dynamic Analyses on Groundwater Level for Many Years in Xianyang City of Shaanxi Province

A series of rainfall data of 12 rainfall stations for 28 years as well as the data of irrigation for 28 years in the three big irrigation areas as Baojixia,Jinhuiqu and Yangmaowan in Xianyang City are collected,collated and analyzed.The correlation analyses on the water level series data for 120 monitoring wells in the city are done by the method of mathematical statistics and typical well method,the dynamic variation of groundwater level of the geomorphic units and the cause types are initially identified,and the main problems existing in groundwater development and utilization and the reasonable measures that should be taken are proposed.The conclusions could provide references for the reasonable development and utilization of groundwater resources in Xianyang City.
