Abstract
Selecting the daily precipitation, temperature, evaporation, etc., in 16 meteorology stand in the upstream of Liujiaxia reservoir, applying climatic change tendency analysis, we analyzed the change rules of the climatic factors, such precipitation, rainy days, temperature, evaporation. The results showed: From 1960 to 2007, the precipitation in the upstream of Liujiaxia reservoir in the year presents the weak declining trend. The yearly rainy days has dropped since 1960. After the water storage in reservoir, the precipitation in the year has decreases slightly. After the water storage in reservoir, the rainy days are decreasing in summer and autumn, but they are increasing in spring and winter. The annual mean temperature has assumed the remarkable increasing trend since 1960, the most warming contribution to the upstream of Liujiaxia reservoir is winter warming.
