近些年来,由于水田面积迅速增加,三江平原地下水位普遍下降,“吊泵”和局部超采现象时有发生,并引发了一系列水环境问题,因此,三江平原地下水资源动态平衡急需恢复。为解决上述问题,以黑龙江省农垦红兴隆分局为例,采用层次分析法(AHP)对地下水人工补给方法进行分析和排序,提出当地最佳地下水人工补给方法为大口井回灌,为红兴隆分局乃至整个三江平原地下水人工补给实践和农业可持续发展提供了科学依据。
The rapid increase in paddy field acreage has led to wide descending of groundwater level in the Sanjiang Plain in recent years, which has led to more and more "hanging pumps" and partial overpumping occurring at times and a series of water environmental problems as well. Therefore, the groundwater resources in the Sanjiang Plain need to be recharged urgently. In order to solve the above-mentioned problems, the authors took land reclamation in Hongxinglong Branch Bureau of Heilongjiang Province for example, analyzed and confirmed the order of groundwater artificial recharge methods, presented the optimum groundwater artificial recharge method by applying the analytic hierarchy process (AHP). Our research can provide a scientific gist for groundwater artifi- cial recharge practice and sustainable development of agriculture in Hongxinglong Branch Bureau.
