For studying the characteristics and changing tendency of precipitation under the effect of global change in Hotan Prefecture,daily precipitation data from seven meteorological stations,including annual precipitation (Pm),annual precipitation days (Ds),and precipitation intensity (Pi),from 1961 through 2015 were analyzed. The result revealed that the annual mean Pm,Ds and Pi had been increasing,with the rates of 3.7 mm·(10a)~(-1),1.15 d·(10a)~(-1) and 0.046 mm·d~(-1)· (10a)~(-1),respectively; Pm and Ds had a big change in 1986.1986 was the year of climatic transition for the annual average precipitation and precipitation days in the prefecture,and so did the spring and summer precipitations,except for winter. In the prefecture,annual mean Pm was 44.0 mm,with 42.4% at the light precipitation level and 78.4% in spring and summer. Annual mean Ds was 49.8 days,with 95.3% at mini and light precipitation levels,and the summer precipitation days took 48.0% of the year-round. The result also showed that there was an increasing tendency for Pm and Ds at all levels,of which the most distinct increasing reason for Pm and Ds was the increase at light and moderate precipitation levels. Besides,the seasonal precipitation and precipitation days also had increased,especially in summer; Pi also had increased except for spring. From above analyses the following conclusion can be drawn: precipitation in spring and summer determines the annual precipitation; light level Pm and Ds are the chief forms of Pm and Ds,and Ds is the key factor to determine the Pm; precipitation and precipitation days have obvious climate change,is now at the stage of increase after the turning point; the increase of precipitation and precipitation days at light and moderate precipitation levels are the main characteristics of the present annual variation of precipitation.
