Abstract: The lower Liaohe River plain is located at the center of the former Liaoning industry foundation. Groundwater supply contributes 65% of the total water supply, however the environmental and hydrogeological problems caused by groundwater development are very serious, not only affecting the eco-environment improvement, but also a serious “bottleneck” to a regional economy development. Hence the significance in carrying out the research on ecological groundwater table and its regulation is very important. Based on the precipitation infiltration and evaporation fundamentals and combined with field experiment results, two series of ecological groundwater table standards were constructed by adopting the method of scenarios analysis. The two schemes in the second scenario: one considered the regulation function of aquifer and the other did not, were evaluated; thirdly, the quantity of ecological modulation was calculated from the groundwater depth and by comparing the topographic and ecological groundwater depths, using of the Golden Surfer software; finally, the modulating countermeasures for groundwater sustainable development were discussed. The results of this research, in some degree may widen the research fields of eco-environmental water demand.

Key words: lower Liaohe River plain, the ecological groundwater table, water quantity regulation
