This paper deals mainly with the mangement of water resources with the chara cteristics of supplemental irrigation for water-saving and prevention of drought,waterlogging and salinization.The indexes for dynamic control of groundwater tables in different seasons are also proposed.The relations between rainfall and the rising of groundwater table,between river-canal irrigation and the rising of groundwater table between evaporation and the decline of groundwater table and between well irrigation and the decline of groundwater table are analysed.Some empirical formulas are obtained from statistical analyses.Finally,according to the principle of both meeting the requirements of irrigation and controlling drought,waterlogging and salinization comprehensively,the management and control sche mes of water resources for different hydrological years in different regions and under the condition of conjunctive use of surface water and ground water are given.
