Quantitative Study on Eco-Environmental Water Demand of Urban Water System

Article Preview

Abstract:

Eco-environmental water demand of urban water system should be that of certain quality, which is necessary for it to develop its normal functions. The water system includes Dongchang Lake, Tuhai River and Old Canal in Liaocheng City, Shandong Province, China. The multiannual mean optimum, medium and minimum eco-environmental water demand of Dongchang Lake are respectively 2922.9×104m3, 2334.7×104m3 and 1746.4×104m3. Those of Tuhai River are respectively 4757.9×104m3, 2865.7×104m3 and 1919.7×104m3. Those of Old Canal are respectively 348.0×104m3, 277.9×104m3 and 207.9×104m3. Then those of the water system in Liaocheng City are respectively 8028.8×104m3, 5478.3×104m3 and 3874×104m3. These results can provide basis for protecting its eco-environment and promoting its sustainable usage.
