【摘要】 以位于祁连山西段疏勒河上游流域的钻孔及冻土地温数据为基础,在等效高程方法的基础上,进一步分析了坡向因素对多年冻土地温的影响.以坡向为分类条件,分别建立了不同坡向地形条件下的多年冻土年均地温模型.借助于GIS技术对整个上游流域的多年冻土年均地温的空间分布特征进行了模拟,以青藏高原多年冻土分带方案为标准对冻土地温进行了分带特征的划分.与已有的青藏高原冻土图相比,本研究结果具有更高的精度.更多还原

【Abstract】 Permafrost temperature is a valid index to illustrate permafrost development and distribution characteristics. Taking the boreholes and the measured ground temperatures of permafrost as the basis data, permafrost temperature models were constructed to model and map the spatial distribution of permafrost in the upper area of Shule River. The zoning characteristics of the mountain permafrost were analyzed based on the scheme of classifying the permafrost on Qinghai-Tibetan Plateau into zones. Compared the results with the previous Qinghai-Tibetan Plateau Permafrost Map, the results had a higher accuracy.更多还原
