摘要
对漠河2000~2005年逐月土壤温度数据进行整理和分析,从中选取0 cm、-40 cm、-80 cm和-160 cm 4个深度点的逐月土壤温度观测资料,从不同角度绘制土壤温度变化曲线,对不同深度土壤温度的逐月变化规律、变化幅度、极值出现时间、1 a中不同深度土壤温度的变化幅度、垂向梯度大小等问题进行研究分析。得出土壤温度的垂向变化规律以及土壤温度随时间的变化规律,为高寒冻土区农业、建筑业的规划研究提供参考依据。
The monthly soil temperature data of Mohe are compiled and analysed from 2000~2005, and the soil temperature observation data at four depth, namely 0 cm, - 40 cm, - 80 cm and - 160 cm, are selected to draw the variation curve of soil temperature in order to find the monthly variation law for soil temperature, variation amplitude, appearing time of maximium, temperature variation amplitude in a year at different depth, and vertical temperature variation gradient of the soil temperature is analysed. The vertical variation and temporal variation law of the soil temperature are studied. It provides reference and foundation for agriculture and construction in frozen area. Key words:
