【 摘 要 】

In order to understand the characteristics of water supply and water usage in Beijing in recent 15 years, a variety of statistical datasets were collected and field investigations were carried out, to analyze the total water resource, the characteristics and trends of water resource supply, utilization and distribution during 2000-2014. The results showed that the total amount of water resources in Beijing is maintained at 1.61∼3.95 billion m3, and the surface water accounts for about 1/3, and the groundwater accounts for 2/3. Agricultural water and living water were the dominated consumption in the past 15 years in Beijing, accounted for 35.3% and 38.9% of the total amount, followed by industrial water, which accounting for 17.9% of total water consumption, and water used in environment is relatively small, only accounting for 7.8% of the total amount. This study can provide theoretical support for the establishment and management of water conservation policies and the rational utilization of water resources in Beijing.
