摘要
Decrease in groundwater levels and deterioration in ecosystems have been observed in recent years in the North Plain of the Urumqi River basin.In order to achieve the sustainable groundwater resources development,four groundwater development scenarios were designed in accordance with the water resources master plan of the Urumqi River basin.The scenarios include: 1) the business as usual; 2) the increased recharge; 3) the decreased abstraction; and 4) the combined scenario of increasing recharge and decreasing abstraction.A transient groundwater flow model was used to simulate the effects of these 4 scenarios.The simulation started from 2007 and end in 2050.The simulated changes in groundwater levels,groundwater balance components and drawdown distribution were analyzed.
