三江平原建三江地区地下水属典型半承压类型,其中创业农场又是典型井灌区,截至2000年水稻种植已占全部耕地的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,但没有产生局部地下水下降漏斗;而且地下水年下降率自1999年以来虽有逐年下降趋势,但本场具有近1亿m3/a可开采的地下水资源,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 in Jianjiangjiang Sanjiang Plain is a typical type of semi-pressure. Among them, the venture farm is a typical well irrigation area. As of 2000, rice cultivation accounted for 97% of the total cultivated land, and the highest exploitation intensity was the Sanjiang Plain. By analyzing the groundwater dynamic data from 1997 to 2001, the groundwater descended from 2 87 m between 1997 and 2001, with an average decrease of 0 57 m per year, but no local groundwater descending funnel was produced. However, the annual decline rate of groundwater has been decreasing year by year since 1999 The field has nearly 100 million m3 / a of groundwater resources can be exploited, groundwater depth is still within 10m. If we can use the local groundwater to stimulate the good objective conditions of supply, groundwater depth and then appropriate to reduce the depth (within 15m), to achieve the balance of mining, the groundwater is not necessarily over-exploitation.
