[Abstract]:High intensity irrigated agriculture in the world has caused serious groundwater crisis and threatened the sustainable operation of agro-ecosystem and economic society. The agricultural system supported by groundwater is facing serious water resources problems in the northern farming area of China, especially in the North China Plain. In the past 60 years, the high plains of the United States have relied on groundwater consumption to support agricultural production. The total production of wheat and corn has increased by 2 and 10 times respectively, but these agricultural achievements have been achieved at the cost of cumulative consumption of about 336 billion m3 of groundwater. The ability of agricultural system to cope with extreme drought events was reduced after 1980. After 1980, the consumption rate of groundwater was reduced in the northern part of the high plain by means of good groundwater recharge conditions, limited exploitation of groundwater and popularization of sprinkler irrigation technology. However, in the high plains, groundwater resources in the south are still out of balance, which leads to the continuous decrease of groundwater resources; while the groundwater conservation in the northern region is not effective in reducing the level of nitrogen fertilizer application in farmland, Lead to serious groundwater pollution in shallow groundwater area. Therefore, in the present practice of controlling groundwater overexploitation in North China Plain and North China's groundwater irrigation area, it is necessary to control and control agricultural non-point source pollution with consideration of quality and overall planning.
