英文摘要	Air temperature (AT) is a subsystem of a complex climate. Long-range correlation (LRC) is an important feature of complexity. Our research attempt to evaluate AT's complexity differences in different land-use types in the Heihe River Basin (HRB) based on the stability and LRC. The results show the following: (1) AT's stability presents differences in different land-use types. In agricultural land, there is no obvious variation in the trend throughout the year. Whereas in a desert, the variation in the trend is obvious: the AT is more stable in summer than it is in winter, with T_a ranges of [8, 20]°C and SD of the AT residual ranges of [0.2, 0.7], respectively. Additionally, in mountainous areas, when the altitude is beyond a certain value, AT's stability changes. (2) AT's LRC presents differences in different land-use types. In agricultural land, the long-range correlation of AT is the most persistent throughout the year, showing the smallest difference between summer and winter, with the Hs range of [0.8, 1]. Vegetation could be an important factor. In a desert, the long-range correlation of AT is less persistent, showing the greatest difference between summer and winter, with the Hs range of [0.54, 0.96]. Solar insolation could be a dominant factor. In an alpine meadow, the long-range correlation of AT is the least persistent throughout the year, presenting a smaller difference between summer and winter, with the Hs range of [0.6, 0.85]. Altitude could be an important factor. (3) Usually, LRC is a combination of the T_a and SD of the AT residuals. A larger T_a and smaller SD of the AT residual would be conducive to a more persistent LRC, whereas a smaller T_a and larger SD of the AT residual would limit the persistence of LRC. A larger T_a and SD of the AT residual would create persistence to a degree between those of the first two cases, as would a smaller T_a and SD of the AT residual. In addition, the last two cases might show the same LRC.
