怀柔应急水源热备涵养期地下水资源变化分析

Analysis on the variation of groundwater resources of Huairou in emergency water source heat preservation period

2015年9月7日怀柔应急水源地进入热备涵养期，按照地下水10万m^3／d的开采规模热备运行，总体相对减采幅度达50％，经地下水动态监测和水资源变化分析，怀柔应急水源地周边潜水位明显上升，加之南水北调水源向密怀顺地区引水回灌，以及区域的补给，地下水储量呈现回升态势，热备涵养初见成效。

On September 7, 2015, Huairou emergency water source was into the heat preservation period, when it was running with 100 000 m^3 the groundwater exploitation scale, and its total relative reduction mining was 50%. Based on groundwater dynamic monitoring and analysis of water resources change, submersible water level surrounding Huairou emergency water rised obviously. Beside, water from the South-to-North water diversion recharged to this region, and the regional supply as well induced the rebounding trend of groundwater reserves, which indicated that heat preservation achieved initial success.
