Inter-annual and seasonal characteristics of groundwater table fluctuations in the urban area of Qianxian County，Yangmaowan irrigation area，and Baojixia irrigation area were analyzed based on the groundwater table data collected from seven monitoring wells between 1992 and 2007，along with DEM which reflects the topography and drainage system distribution of the study area． The study area is located in the transition zone from the North Weihe to Guangzhong region． The results indicate that the groundwater table in the urban area of Qianxian County rose at a rate of 0． 31 m/a during the study period． However，the groundwater tables in Yangmaowan and Baojiaxia irrigation areas were declining in the past sixteen years; the groundwater table of Yangmaowan irrigation area declined faster than that of Baojiaxia irrigation area． In wet years，the groundwater tables of the wells that is close to reservoirs rose quickly due to the combined effects of both reservoir recharge and rainfall infiltration． On the contrary，the groundwater tables of the wells that is far from reservoirs rose more slowly as rainfall infiltration was the only recharging source． The irrigation areas had the relatively higher groundwater tables in February and October and the lower ground-water tables in July． Combination of channel and well irrigation is suggested for the sustainable use of groundwater resources in Qianxian County．
