| 内容記述 | Groundwater forms an important source of water supply in arid and semi-arid region. Optimum conjunctive utilization of surface and groundwater resources has become extremely important to fill the gap between water demand and supply. Hetao Irrigation District (HID) is the largest irrigation district along the Yellow River and its groundwater table is shallow. The project of Water Saving Reconstruction (WSR) has been conducted for the purpose of keeping the Yellow River free from drying up. The water taken from the Yellow River is about 5.2 and 4.0 billion m3/year before and after WSR, respectively. Thus, the gap between water demand and supply has increased manifolds due to increased agricultural activities and reduced irrigation water from the Yellow River. To satisfy the growing water demands, more groundwater has to be pumped since the water taken from the Yellow River is decreased. In this study, the hydrogeological condition and groundwater behavior will be analyzed based on long-term hydrogeological database. Then the causes of groundwater table drawdown will be discussed. Moreover, the vulnerability of groundwater in HID due to agricultural activities will be analyzed. Furthermore, the contribution of groundwater in meeting the crop water requirements varied with the water-table depth will be discussed. Finally, the importance of community management of groundwater and other attempts to regulate its use on checking over-extraction of groundwater will be discussed as solutions for sustainable development and management of groundwater resources in this arid region. | |||||
