浅析三江平原建三江地区便业农场地下水资源

Preliminary study on groundwater resources in Chuangye Farm of Jiansanjiang region of Sanjiang Plain

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 waterBy 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 287 meters,the average falling ratio is 057 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 yearthe depth of laying of groundwater is still within 10 meters
