了解气候变化影响下的地下水潜在补给变化对于地下水资源的科学管理与评价是非常必要的。以栾城生态试验站为典型研究区, 联合应用 ClimGen 天气发生器和地下水补给 Visual HELP 模型, 对未来气候变化情景下的地下水潜在补给速率进行了评估。结果显示: 在降水减少 10% ( P) 、温度上升 2 e( T ) 以及两者同时发生( P& T ) 三种情景下, 未来(2011 年- 2040 年) 地下水多年平均补给速率相比基准( 1961 年- 1990 年) 分别下降了 23133% 、4142% 、26101% , 其中降水的减少对地下水入渗补给的影响尤为明显。该项研究对于指导地下水资源的科学管理与可持续开发利用具有重要意义。
Understanding the changes of the potential recharge of groundwater under the influence of climate change is very necessary for the scientific management and evaluation of groundwater resources. Taking Luancheng Ecological Experimental Station as a typical research area, the Visual HELP model of ClimGen weather generator and groundwater recharge was applied to evaluate the potential recharge rate of groundwater in the future climate change scenarios. The results showed that the average recharge rate of groundwater in the future (2011-2040) was significantly lower than the baseline (P <0.05) in the three scenarios of a 10% decrease in precipitation (P), a 2 e (T) increase in temperature and a simultaneous P & amp; 1961-1990) decreased by 23133%, 4142% and 26101% respectively. The impact of the decrease of precipitation on groundwater infiltration and replenishment was especially obvious. This research is of great significance to guide the scientific management and sustainable development and utilization of groundwater resources.
