| 摘 要： | 纬度和高程是决定我国高山/高海拔多年冻土分布的主要宏观因素,也是建立各类高山/高海拔多年冻土分布模型的首要考虑因素.文章旨在建立一个易于区域对比的、综合纬度和高程双重影响的定量化的等效高程评价指标.以高斯曲线模型为基础,通过对其做导数变换,界定了此宏观尺度模型在中小尺度空间上适用的纬度范围.以位于祁连山区西段疏勒河上游...

| Abstract: | Latitude and elevation are the main macro-factors for determining the distribution of alpine permafrost in the Qilian Mountains,China,and then,are the primary factors for a permafrost distribution model.Purpose of this paper is to construct a general index,the equivalent-elevation,which could combine the double effects of latitude and altitude on permafrost and could be used to the comparison of permafrost distribution in different mountainous areas.Based on the Gaussian curve,the latitudinal range,in which... |
