| 中文摘要:华北平原是我国粮食的重要产地.地下水资源是该地区的主要供水水源,在开采量增加和气候变化的影响下,水资源问题制约着该地区的发展.特别是近些年来降水量减少、气温呈上升趋势,使本来就少的水资源更削弱了补给资源.通过对降水、蒸发、地表径流、地下水流场变化、地下水资源的系列变化分析,认为降水量减少、气温升高、人类治水工程和开采地下水等因素是造成本地区水资源减少的重要原因. |

| An Analysis of the Influence of Human Activity and Climate Change on Water Resources of the North China Plain |

| Abstract:The North China Plain is an important area for food production, and the underground water resources constitute the main water-supply source of this region. The increasing production quantity and climate change have restricted the development of water resources. With the trend of decreasing precipitation and ascending air temperature in recent years, the originally insufficient water resources have continuously reduced the water supply. On the basis of an analysis of precipitation, evaporation, surface runoff, changes of underground water flow field and a series of changes of underground water resources, it is thought that such factors as decreasing precipitation, ascending air temperature, human river-taming work and exploitation of underground water seem to be the most important factors responsible for the decrease of water resources in this region. |
