Analysis on the Inlfuence to reduce exploitation of the Huairou Emergency Wellhead
摘要
Abstract
On the basis of themeteorological and groundwater monitoring data for many years in Huairou emergency wellhead, this paper analyzes the groundwater level, water quality and dynamic water level before and after the Huairou emergency wellhead reducing exploitation in September 2015. At the same time, the evaluation of emergency wellhead conservation effects on water source and the surrounding groundwater system has also been carried out. The results show that the groundwater level in the central area of Huairou emergency wellhead has declined to 31.34m till August 31, 2015. After the water source is reduced, the water level in the emergency water source area and the surrounding area is obviously recovered. Compared to August 31, 2015, average of region ground water level has increased 1.69m on December 31, 2015.The largest increase occurred in the central area and the southern region’s increase is larger than that of the northern region. The average dynamic water level of shallow wells is increased by 8.07m and the average dynamic water level of deep wells increased by 18.34m. In the early stage of the reduction, the water quality of the deep conifned aquifer is deteriorated, which is close to the shallow conifned water. As the time goes by, the ground water level is increased and the water quality is restored to the level before the reduction. As the capital's largest emergency wellhead , Huairou emergency wellhead for conservation in the case of new water resources of South-to-North Water Diversion, has important signiifcance to ensure the safety of water supply in the capital.关键词
