Abstract: The study aims to analyze stability, change trend and abrupt change characteristics of yearly and seasonal precipitation. Ultimate ratio, standard deviation, climate inclination rate and Mann- Kendall nonparametric test were adopted based on the monthly precipitation from 1951 to 2012 of Dongling District observation station of Shenyang. The results showed that, yearly precipitation of Shenyang was relatively stable with fluctuation of descending trend since 1951. The period from 1953 to 1982 had significant decrease of precipitation and climate inclination rate was -84.822 mm per 10-year. The period from 1983 to 2012 had a slow decrease of precipitation. In 1961, yearly precipitation showed abrupt decrease and then precipitation averagely decreased 146.2 mm. In recent years, precipitation in spring was not stable and precipitation series showed slightly increase but no abrupt change. Precipitation in summer was relatively stable with a decreasing trend. Inclination rate was -15.916 mm per 10-year. In 1961, precipitation showed abrupt decrease and then precipitation averagely decreased 120.0 mm. Precipitation in autumn was very unstable with a slightly decreasing trend. It showed no abrupt change. Precipitation in winter was unstable with a slightly increasing trend. It showed obvious increase for approximate 20 years. In 2004, precipitation showed abrupt increase and then precipitation showed average increase of 14.7 mm. Before 1982, yearly precipitation and precipitation in summer and winter decreased obviously, after 1983, changes were relatively stable. After 1996, precipitation in winter and spring shows increasing trend.
