Water resources assessment issues and isotope hydrology application in china

摘要

As one of the largest countries in the world, china has a highest population and great potential in water resources and land. Water is a key issue for sustainable development in the fu- rure, because the average water and land availability per-capita is much lower than the world av- erages. Water resources assessment plays a very important role. However, certain problems could not be solved due to lack of hydrological data, such as groundwater in arid and semi-arid zones.
