山区地表温度垂直递减率的时空分布特征——以祁连山为例

Spatio-Temporal Variations of Surface Temperature Lapse Rate on Qilian Mountains

摘要: 综合运用Excel、Arcgis等软件，以37.7˚N~38.4˚N、99.8˚E~101.4˚E范围内祁连山区(黑河源头东支流域)的近地面温度数据为基础，绘制了地表温度垂直递减率在时空分布上的变化折线图，由此对祁连山区的地表温度垂直递减率的时空分布特征进行初步分析，为相关领域研究提供基础资料。分析结果显示：总体看来，地表温度垂直递减率的分布与热量条件的相关关系较为显著。空间分布上，地表温度垂直递减率全年分布规律基本与山区地形、热量条件分布情况一致，阳坡地表温度直减率明显高于阴坡；时间分布上，各个季节的地表温度垂直递减率分布各不相同，不同时相的地表温度垂直递减率也有差异。

Abstract: By integrated use of Excel, Arcgis software and based on the near surface temperature data to 37.7˚N - 38.4˚N, 99.8˚E - 101.4˚E range within the Qilian Mountains (east branch source of Heihe River Basin), the paper drawn surface temperature lapse rate of change in the spatial and temporal distribution line chart, thereby analyzed its characteristics, and provided basic information for the relevant area of research. Analysis results showed that: Overall, the correlation between surface temperature lapse rate of distribution and thermal conditions was more significant. In the spatial distribution, the annual surface temperature lapse rate is basically consistent with the distribution of mountain terrain and heat conditions. The surface temperature lapse rate of the sunny is significantly higher than that of the shady; in time distribution, the distribution of surface temperature lapse rate in all seasons is different; surface temperature lapse rate at different phases is also different.
