塔克拉玛干沙漠水热通量变化特征及影响因素

Variation in water-heat fluxes and influencing factors in the Taklimakan Desert


摘要(Abstract):

为了研究气候变化导致沙漠地区水热通量的多尺度演变规律及其关键环境影响因子,基于新疆塔克拉玛干沙漠气象国家野外科学观测研究站2022—2023年涡动相关系统连续观测数据,分析塔克拉玛干沙漠腹地感热通量和潜热通量在不同时间尺度上的变化特征及其对环境因子的响应。结果表明:塔克拉玛干沙漠腹地感热通量和潜热通量存在明显的昼夜变化和季节变化,2022、 2023年感热通量累计值达910.34 W/m2,潜热通量累计值仅为222.05 W/m2,表明感热通量在塔克拉玛干沙漠腹地近地表能量流动中起主导作用;环境因子对水热通量的影响随时间尺度的不同而变化;在不同时间尺度上,不同的环境因子对水热通量的贡献度有所不同,土壤温度贡献尤为突出,在能量交换中具有重要作用。
