Through the statistics of the historical data, using the method of mathematical statistics, we analyzed the frequency of drought disasters, grade sequence characteristics, seasonal and internal variations and the cause during the Ming Dynasty. The results show that it happened recorded a total of 55 times, about once every 5 years, given priority to with class Ⅱ drought, accounting for 40% of the total number of drought; Above class Ⅱ proportion was 80%, and was more than half of the total number of drought, it showed that in the Ming Dynasty drought damage was serious. Drought quantity was less and lighter in the early Ming Dynasty; drought began to increase rapidly and became heavier in medium and late of that dynasty. Most drought seasons were the year of drought and the spring drought. The dry and cold climate after the 16th century created a degree of frequent and severe droughts. And the growth of population, continued demand for land resources, the excess requirements for water resources and vegetation eventually led to the runoff reduction and the frequent droughts.
