摘　　要：利用安徽肥西、全椒的边界层观测资料，采用半小时的滑动平均和波文比能量平衡法分析计算了局地大气稳定度和不同下垫面条件下的地表感热通量的差异。结果表明：不同下垫面对感热通量变化影响不同，清晨影响最大，午后影响逐渐减弱，其成因较多。The different sensible heat flux and the stability under different underlying surface conditions with BREB method was analyzed, according to the boundary layer observations of Feixi and Quanjiao in Anhui province, after taking half-hour moving average. The result shows the sensible heat flux is influential by different underlying surface： maximum in the early morning and gradually decays after noon with several reasons.
