Abstract:: Based on maximum temperature, minimum temperature, monthly mean temperature, relative humidity, wind speed, sunshine duration and rainfall data collected from four meteorological stations during 1957—2013 in Kashi area, we used Penman-Monteith model, regression analysis, accumulative anomaly and Mann-Kendall nonlinear mutation test method to analyze annual potential evapotranspiration dynamic change and its influence factor of time series. The results show that: (1) in the past 57 years, the potential evapotranspiration in Kashi and Bachu showed the decreasing trend and its tendency rates were -7.53 mm/decade, -7.47 mm/decade, potential evapotranspiration of Tashikuergan and Shache increased with the tendency rates of 8.27 mm/decade and 6.25 mm/decade; (2) during the four seasons, the dynamic change tendency rate was higher in summer than spring and autumn, and lowest occurred in winter; (3) there was a significant difference among the potential evapotranspiration mutation points in Kashi area; the annual potential evapotranspiration mutation point of Kashi occurred in 1981, 1962 for Bachu, 1974 and 1983 for Tashikuergan, annual potential evapotranspiration mutation points of Shache occurred in 1961, 1965, 1968 and 1978; (4) the wind speed and sunshine hours have the effect on the annual evapotranspiration in Kashi area.
