摘　　要：以三江平原建三江管局大兴农场为例,根据井数、单井出水量和布井位置疏密的不同,设计了3个农业灌溉取水工程布置方案,并运用Modflow软件对未来5 a的地下水位状况进行计算预测,通过对计算结果的对比分析得出最优布置方案。结果表明,单井出水量相同的条件下,布井数量越多,总用水量越大,地下水位下降越严重;总用水量相同的条件下,单井出水量越大,地下水位下降越多;在综合考量的条件下,开采井布局越密集,形成的地下水漏斗越严重。为合理开发地下水,农业灌溉布置最优方案为布井数量适中、单井出水量少和布井相对分散的方案。According to the differences of the well quantity, water yield of single well and the density of well lay- out, with Daxing farm as an example in Sanjiang plain, three layouts of water intake projects of agricultural irriga- tion were designed, and Modflow software was used to calculate and forecast the levels of the groundwater in the following 5 years in future. Through the comparison and analysis of the calculation results, the optimal arrange- ment scheme were obtained. The results showed that, under the condition of the same single well water yield, the more the well quantity, the greater the total water amount and the slower the underground water level; Under the same total water consumption, the greater the single well water yield, the slower the underground water level; Un- der the condition of comprehensive consideration, the more intensive the well spacing, the more serious the for- mation of groundwater funnel. In order to reach the reasonable development of groundwater, the optimal scheme of agricultural irrigation wells layout is recommended to be moderate number of well spacing, less water yield of single well and relatively dispersed well spacing project.
