摘　　要：从近 30 0a来太行山平原典型区地下水入渗补给演化特征、机制和未来 5 0a区域水循环中水分通量演化趋势 3个方面 ,阐明了山前平原地下水补给能力的周期可变性和该区现状资源型缺水的客观性。在此基础上 ,提出了进一步开展百年尺度水循环演化趋势基础研究的建议。The periodic variability of shallow groundwater recharge capacity and the deficiency of water resources in Taihangshan piedmont plain are expounded from the evolutionary characteristics and mechanism of shallow groundwater recharge over the last 300 years.The evolutionary trend of the regional hydrologic cycle from 2000 to 2050 is predicted.According to the results of the research, the quantity of the groundwater recharge in Taihangshan piedmont plain in the last 300 years is not the smallest in the whole period since Early Holocene, and is not the smallest during the last 1 000 years; the quantity of the groundwater recharge in the 20 th century is not the smallest during the last 300 years, and the period with the least groundwater recharge must have been from 1820 to 1847. The groundwater recharge in Taihangshan piedmont plain from 2001 to 2010 will probably increase. It is therefore suggested that the trend of the regional hydrologic cycle in a period of a hundred years should be studied as soon as possible.
