Water resources and their availability were studied in order to alleviate the increasing tension between available water resources and water demands from socio-economic development in Northern ShaanxiProvince.We analyzed the characteristics of water resources and usages in Northern Shaanxi Province,thencalculated the surface available water resources and total available water resources by deducting river ecological basic flow and flood discharge from surface water resources.We also summarized spatial distribution patterns of the available water resources and discussed the current usage and future trends of the other water resources.The total capacity of water resources was low in the study area,accounting for approximately 1.6×109 m3.More importantly,the available rate was as low as 40%.The available water resources mainly presented in Yulin area.
