| Abstract: |
| Precipitation is important water resource supplied for the river runoff. The study on the precipitation characteristics has significance for the analysis of runoff and water resources development and utilization. In this paper, with precipitation series at 28 precipitation stations in the Taizi River Basin from 1967 to 2016, the precipitation characteristics were analyzed with Kendall test method and Kriging spatial interposition method. The results showed that the annual precipitation and four seasons precipitation failed the Kendall test at the 0.01 significant level. The tendencies of annual precipitation, spring and autumn precipitation reduction are insignificant in recent 50 years, summer and winter precipitation indicate indistinct increasing trend. The annual and seasonal precipitation increase from the northwest to the southeast in the Taizi River Basin. |
