摘要:
选择祁连山大野口为试验流域,研究土壤温度在海拔、坡向、坡度、深度等空间的变化特征。结果表明:1.土壤温度随海拔升高呈波动性降低,降低率约为0.74 ℃/(100 m); 2.阳坡土壤温度比半阳坡高1.3倍、比半阴坡高2.2倍,半阳坡土壤温度比半阴坡高1.6倍; 3.土壤温度随坡度增大而略呈降低趋势; 4.土壤温度与深度关系为Sdt=-0.0536d+9.192(R2=0.994),温度随深度降低率约为0.536 ℃/(10 cm),呈线性函数关系; 5.亚高山灌丛林比乔木林土壤温度低1.6倍、比草地低2.3倍,乔木林土壤温度比草地低1.4倍; 6.从土壤温度的变化程度分析,高海拔半阴坡灌丛林土壤温度变化最剧烈,低海拔阳坡草地土壤温度变化较小; 在0～80 cm土层范围内,表层土壤温度变化最剧烈,40～60 cm土层的温度变化最小。研究可为流域水源涵养功能、水资源管理及利用、林分结构调控及土壤水资源植被承载力等研究提供基础数据和参考资料。
