Abstract
[ Objective ] The study aimed at analysing the changing characteristics of meteorological elements in Mount Qomolangma Nature Reserve. [Method] Based on the ground observation data of Nyalam and Tingri station in Mount Qomolangma Nature Reserve, temperature, ground temperature, evaporation, precipitation and snow depth were analyzed. [Result] The annual average temperature of Nyalam and Tingri tended to increase since the 1960s, especially Tingri station. The annual mean ground temperature also increased since observational data was available in 1986, and was more prominent in Nyalam station, with growth rate of 0.9 ℃/10 a during recent 25 years. The average temperature in cold and warm season showed increasing trend, but the average temperature in cold season rose more fastly than that of warm season. There was a regional difference in annual average precipitation and evaporation. That is, the annual average precipitation and evaporation of Tingri station enhanced since the early 1980s, but those of Nyalam station slightly decreased since the late 1980s. Annual snow depth of the two stations showed decreasing trend, but the variation of snow depth in Nyalam station was larger, that is, the snow depth increased from the 1960s to late 1980s, while decreased since the 1990s. [Conclusion] The research could provide scientific references for the protection of ecological environment in Mount Qomolangma Nature Reserve in future.关键词
