摘要
三江平原建三江地区地下水属典型半承压类型，其中创业农场又是曲型井灌区，截至2000年水稻种植已上全部耕地的97％，创地下水开采强度三江平原之最。通过分析1997－2001年的地下水动态资料，1997－2001年地下水下降2.87m，平均每年下降0.57m，但没有产生忆部地下水资源，地下水埋深仍在10m之内，若能利用本地区地下水激发补给的良好客观条件，在地下水再适当下降深度（15m以内），达到采补平衡，本场地下水还不一定超采。
The groundwater character of Jiansanjiang region in Sanjiang Plain belongs to half confined waterBy conducting a detailed analysis based on the groundwater dynamic changing data dating from 1997 to 2002,the results are drawn out that the groundwater level fell with a total depth of 287 meters,the average falling ratio is 057 meters per year;the depression cones have been not found;the falling ratio appears in a tend of decreasing gradually from 1999 to now,if the exploitation quantities of the farm are limited within 100 million cubic meters per yearthe depth of laying of groundwater is still within 10 meters
