[目的]为开展吉林松嫩平原区地下水动态研究提供理论依据。[方法]分析了吉林松嫩平原区地下水动态及其驱动因素。[结果]自20世纪60年代以来,吉林松嫩平原区气温逐渐升高,平均气温累计上升2℃;降水量逐渐减少,特别是西部地区降水量减少的趋势更加明显;同时地下水开采量不断增加,2008年达到28亿m3。在多种因素驱动下,区域地下水水位发生明显变化,潜水水位在西北部扇形地下降尤为明显,其他地区较为稳定,部分地区有所回升;承压水水位总体下降较快,个别地区有所回升。[结论]研究区地下水环境的总体恶化趋势不可避免,但可通过制定科学规划、合理开采地下水资源来减缓恶化进程,实现区域地下水资源的可持续利用。
[Objective] The research aimed to provide theoretical basis for carrying out groundwater dynamic research in Songnen Plain, Jilin Province. [Method] The groundwater dynamics and its driving factors in Songnen Plain of Jilin Province were analyzed. [Result] Since the 1960s, the temperature in Songnen Plain of Jilin Province gradually increased, the average temperature increased by 2 ℃, the precipitation decreased gradually, especially the decrease of precipitation in the western region became more obvious. Meanwhile, the exploitation of groundwater increased continuously In 2008 reached 2.8 billion m3. Driven by many factors, the groundwater level in the area changed significantly. The submarine water level dropped particularly fan-shapedly in the northwestern part of the country, while the rest of the submarine water area was relatively stable and some parts of the submarine water level rose back. The pressure water pressure level dropped rapidly in general and rebounded in some areas . [Conclusion] The overall worsening trend of groundwater environment in the study area is inevitable, but the process of deterioration can be slowed down through the formulation of scientific planning and rational exploitation of groundwater resources so as to realize the sustainable utilization of regional groundwater resources.
