摘要
为研究不同开采条件对三江平原地下水位的影响,构建了地下水数值模拟模型,并设置4种开采和降雨情景,对该区域不同降雨年型、农业节水情景下的地下水流场进行预测。结果表明,降雨和农业开采在不同程度上对流域地下水位产生影响,相同的降雨条件下,采取农业节水有利于减缓地下水位下降的问题,对地下水保护具有重要意义。
In order to study the influence of different mining conditions on the groundwater level in the Sanjiang plain,this paper established the groundwater numerical simulation model,and four mining and rainfall scenarios were set up to predict the groundwater flow field under different rainfall years and agricultural water-saving scenarios.The results show that rainfall and agricultural exploitation have different impacts on the groundwater level of the basin.Under the same rainfall conditions,the adoption of agricultural water-saving is beneficial to slowing down of the groundwater level,which is of great significance to the protection of groundwater.
