| 摘 要： | 对三江平原20世纪50—60年代、70—80年代和90年代至今的地下水资源量进行了调查对比,结果表明:低山丘陵区和平原区主要接受大气降水的补给,平原区还接受丘陵区的地下水侧向流补给及河水补给,排泄在早期以蒸发为主,后期以人工开采为主;三江平原地下水循环演化是从20世纪70—80年代开始发生负均衡变化的,而在农业经济发展的90年代负均衡更加显著,形成了一些地下水超采区。

| Abstract: | The changes of groundwater resources in Sanjiang Plain were compared in different decades,i.e.the periods of 1950-1960s,1970-1980s and since 1990.In the study area,hilly areas and plains are replenished mainly by precipitation.Hilly plains also receive lateral recharge of groundwater and river supply.Evaporation is mainly discharge way in the early days.Then withdrawal becomes the major drainage method.Evolution of groundwater in Sanjiang Plain begins to be negative balance since 1970-1980s.The greater withdrawal in 1990s with the development of agricultural economy happens which has formed groundwater overdraft districts. |
