Abstract: The Kandell'rank verification was used to analyze the tendency of hydrometeor in the Hotian oasis of Xinjiang Autonomous Region from 1954 to 2003.The results showed that the temperature,evaporation increased significantly,while the precipitation,relative humidity and the river runoff decreased not significantly.The results of Rescaled Range Analysis(R/S analysis) showed that changes of each hydrometeor had the persistence.Based on the Hurst index the intensity of the persistence was quantitatively compared.The fractal characteristics of the hydrometeor was described and the fractal dimension was confirmed.

Key words: Hotian oasis, Hotian oasis, Hydrometeor, Persistence, Rescaled range analysis(R/S analysis), Fractal dimension
