On the basis of analyzing the distribution characteristics and the problems about expl-oitation/utilization of water resources in Guanzhong region,from a point of view of harmonious development among society,economy and environment,four modes on rational exploitation/uti-lization of the region's water resources are raised in an overall and systematic way,according to water resources conditions,exploitation/utilization potentials and environmental state.Moreover,in terms of geological,geomorphological,hydro-geological conditions and water resources distribu-tion characteristics,the four modes are further divided into eight sub modes.Also the paper ana-lyzes and studies water resources storage rules,current utilization situation,exploitation potential and reasonable utilization direction of all the sub modes,thereby,points out the direction for de-veloping and utilizing macroscopically water resources and offers scientific proof for allocation,planning and management of water resources.
