[Objedtive] The characteristics of precipitation in the hinterland of Taklimakan Desert were explored to provide support for the construction of ecological environment.[Methods] Based on the hourly precipitation data from April to October during 2005-2014 from Tazhong meteorological station

the rainfall intensity

precipitation and the days of precipitation

etc. were analyzed to describe the rainfall characteristics of Tazhong area.[Results] The diurnal variations of hourly precipitation and rainfall frequency were consistent in the study area. The peaks of hourly rainfall and rainfall frequency both occurred from 23:00 to 08:00

and the minimum value occurred from 17:00 to 22:00. The frequency of rainfall(represented by R1)≤0.5 mm were the most and accounted for 64.5% of all rainfall events

the following intensities were 0.6 mm≤R1≤1.5 mm and R1≥4.6 mm. The contribution of 0.6 mm≤R1≤1.5 mm was the highest and accounted for 26.4% of the total precipitation amount. In terms of the magnitude of precipitation(R)

light rain or less of 0.1 mm≤R≤2 mm occurred the most

but R≥6.1 mm precipitation events had the highest contribution to the total precipitation

the value was 52.6%. The rain was more frequently occurred in night time. Moderate rain focused from May to July

especially in June

half of that occurred in the first half of night. The precipitation duration of less than or equal to 5 h accounted for 85.5%.[Conclusion] The precipitation in the study area were mainly composed of short-time night-rain. In recent years

the precipitation of≥6.1 mm showed a trend of stable increase

so the large precipitation in desert area may be possible.
