Based on the rainfall data from 2009 to 2012 in Mahuangtian catchment of Guanling County in Guizhou Province, the rainfall concentration, concentration period and uneven distribution coefficient were analyzed and the annual distribution characteristics of rainfall were studied. The results showed that the moderate or light rainfall in Mahuangtian catchment evenly distributed throughout the year; and heavy rain, rainstorm distributed unevenly; the distribution characteristics of rainfall is approximately the same in dry year or wet year; ten-day rainfalls had an obvious fluctuation, and rainfalls in a month unevenly distributed. Annual precipitation concentration degrees ranged from 0.78 to 0.81, precipitation concentration periods changed in 18 to 20 ten-day, uneven coefficient of annual distribution was greater than 0.8. Erosive rainfall is unevenly distributied, mainly concentrated in May to October, and mostly was from June to July within the total or each year of the four years.
