摘　　要：三江平原建三江地区具有丰富的降水、地下水和过境水资源。在开采地下水资源过程中，由于降低地下水位，可以激发周边地下水和过境水资源对地下水的补给，根据已有的计算成果，进行了新的分析，激发补给量可超过1998年评价的可开采量，有的农场（如创业）已实现这个激发补给量的目标。产生激发补给的原因是本地区属弱承压地下水，开采初期能产生比潜水区大4～5倍的地下水降深，而产生与周边江河水位和周边地下水位较大的水力梯度，通过地下水位等值线的开采前后变化分析，局部地区已增大4～5倍，从而产生且不断增加激发补给。It is rich in water resource such as precipitation, groundwater and transiting water in Jiansanjiang area of Sanjiang Plain. During the course of developing groundwater resource, the decline of groundwater level will arouse recharge from groundwater around and transiting water resource. The article makes a new analysis on the base of datum got before, Through the new analysis, we find that the recharge volume can exceed the workable reserves which was given in ＂the Evaluation of 1997＂, the workable reserves of groundwater is doubled, and on some farms such as Chuangye Farm , the stimulated recharge volume has been reached. The cause of stimulated recharge is the groundwater drawdown and greater groundwater level gradient caused by groundwater development. During the beginning period of developing artesian groundwater, a drawdown 4～5 times deeper than surrounding groundwater area will be formed, which causes the greater groundwater level gradient between the area where groundwater has been developed and surrounding river water level and groundwater level, By analyzing variation of the groundwater level constant value line, we find that the groundwater level gradient in partial area increases by 4～5 times.
