1 The drought in 2000 The first half of 2000 was the driest year since the founding of Zaozhuang City. From January to May, the average rainfall in the city was 82.1mm, 43.3% less than the same period in previous years, the minimum since the founding of the country with hydrological data. Frequency analysis recurrence period of 250 years once. Due to the small amount of precipitation, the groundwater level in the city dropped a lot. The Shiliquan water source area dropped by 13.10m, the Qingliangquan water source area decreased by 7.95m, the thirsty water source area dropped by 22.06m, and eight groundwater observation wells dried up. Tengsi plain depth of 6m above the funnel area reached 730.7km ~ 2. Most of the city’s small reservoirs dried up and the river was cut off, resulting in a water shortage of 146,700 ha of farmland in the city, with a dry-land area of 56,700 hm to 22,330 hm 2 and an output of 14.59
