Description :
Through detailed statistics and analysis of drought and water disasters in the Weihe Plain in the historical period, the AA. discovered that in more than 2300 years (from 370 BC to 2000 AD), natural disasters occurred most frequently in 2 periods : 610 to 850 AD; 1580 to 2000 AD. Different natural disasters occurred synchronously : when the drought occurred frequently, water disasters occurred frequently in the same periods. The excessive exploitation of natural resources and human disturbance and damages to ecological environment are the major reasons for the increased drought and water disasters.
