| 摘 要： | 根据Monin—Obukhov相似性理论，运用空气动力学方法和能量平衡法，结合2002—2003年小气候资料，分别分析了宁夏南部山区（下称宁南）退耕还草区湍流通量和地表通量（净辐射、感热、潜热和土壤热通量）的分布和季节变化特征，为宁南退耕还草区陆面过程的认识、数值模拟和气候分析提供理论参考依据。

| Abstract: | Based on the theory of Monin-Obukhov similarity and methods of aerodynamic and energy balance,the seasonal change characteristics and eddy momentum flux(including net radiation one,sensible heat one,latent heat one and soil heat one) characteristicsnear surface layer in the region of conversion from farmland to grasslands in southern Ningxiawere analyzedusing the data of microclimatic observation during 2002 to 2003,respectively.Those provide some valuable parameters for the understanding of land process,numerical simulation as well as the local microclimate climate analysis. |
