China Geological Survey, Hydrogeology and Environmental Director YIN Yueping recently pointed out that water shortage has become China's economic and social development of the "bottleneck." In recent years, vigorously carry out the development and utilization of groundwater resources, but in terms of management, and advanced level is still a difference of 10 to 20 years.

    National Assessment of groundwater resources and environmental investigation showed that the use of the available groundwater still great potential. Natural recharge of fresh groundwater resources in the country about 884 billion cubic meters a year, exploitation of underground water resources can be 353 billion cubic meters per year; In addition, every year nearly 260 billion cubic meters of shallow underground, and 14 billion cubic meters of fresh water salinity 1 g to 5 grams of underground water resources available for development use.

    "However, China and the world advanced level in groundwater management is still a difference of 10 to 20 years." YIN Yueping that the differences were mainly in three aspects: First, the extensive groundwater system management mode, the second is yet to achieve commercialization of water pollution, and the third is Automatic monitoring of groundwater level is low.

    Because groundwater management lags behind, irrational exploitation of groundwater resources in a very serious problem, the current land subsidence has occurred in many areas and to crack, groundwater cone of depression, ground subsidence, seawater intrusion, desertification and other environmental issues, half of the country areas of shallow groundwater polluted in varying degrees.

    YIN Yueping that related to the world advanced experience of peer learning is to improve management of groundwater an important way. He disclosed that this year 9 to 13 October, the 34th International Geological Congress Hydrology was held in Beijing from 56 countries and regions, 240 countries will discuss sustainable development of groundwater, regional groundwater system evolution, etc. 9 carried out by academic exchanges.
