1 The status of water resources Hebi City, the total water resources 550 million m ~ 3, the average annual rainfall of 656.0 mm. In 2001, the current amount of water resources was 320 million m 3, of which surface water resources were 110 million m 3, groundwater resources were 270 million m 3, double counting was 0.6 billion m 3, water production coefficient was 0.30 and water production modulus was 14.77 Million m ~ 3 / km ~ 2. In the past decade or so, except for the abundance of water resources in 1996, the amount of water resources decreased significantly. 2 Water Resources Development and Utilization Status In 2001, the city’s water resources development and utilization of 6.0963 million m ~ 3. Among them, 448.1 million m 3 of agricultural irrigation water (including agriculture, forestry and fishing) accounted for 73.5%. 1.1528 billion m 3 of industrial water accounts for 18.9%; domestic water consumption is 461.8 million m 3, accounting for 7.6%. The development and utilization of surface water is 136.6 million m 3, groundwater is 4.7337 billion m 3, of which groundwater accounts for 77.6%. It is the main source of water supply. Utilization of water resources that year exceeded 289.63 million m ~ 3
