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