Abstract: The analysis results of local water resources’ natural characteristics as well as the present situation of artificial regulation show that, there’s still some potentiality of water resources’ artificial regulation in Dalian area. After the comprehensive research about watersheds runoff characteristic, artificial regulation condition and dam groundwater reservoir technology, 5 surface water works, 7 groundwater reservoir works and 13 potential groundwater reservoir zones have been proposed. Water balance indicates that available water resources of 437 640 000 m³/a could be increased through enhancing artificial regulation,which will be significant to resolve the water supply problem in the near future and increases the water supply ability during an emergency in Dalian area.

Key words: water resources, artificial regulation, water balance, Dalian area
