灌溉引起的地下水位下降是北方农业发展面临的主要问题。由于经济和人口增长，地表水几乎不存在，地下水是唯一的水资源。目前，地下水正以每年50至100厘米的速度下降。北方地区的可持续发展需要对地下水资源进行有效的管理。在这项研究中，未来的灌溉模式对地下水位下降的影响进行了研究与MODFLOW的帮助。MODFLOW在该县的五个观测威尔斯进行了校准。校准模型在7年的时间内很好地拟合了观测数据。模拟结果表明，通过减少灌溉量，地下水下降趋势将得到减缓，甚至可能停止。版权所有© 2005年约翰威利父子有限公司。
Declining groundwater levels caused by irrigation is the main problem for agricultural development in Northern China. Due to both economics and increased population, surface water has become almost non‐existent and groundwater is the only water resource left. Currently the groundwater is declining at a rate between 50 and 100 cm per year. Sustainable development in Northern China requires effective management of the groundwater resources. In this study, the effect of future irrigation patterns on the decline of the groundwater table is examined with the aid of MODFLOW. MODFLOW was calibrated for five observation wells in the county. The calibrated model fitted the observed data well over a 7‐year period. The simulated results showed that the groundwater decline would be decreased, and perhaps halted, by decreasing the use of irrigation. Copyright © 2005 John Wiley & Sons, Ltd.
