中文摘要: |
以云南省七个小流域的气象、水文资料,检验了三个含有下垫面参数的陆面蒸发公式,表明傅抱璞公式最佳.作者提出了一个反映地形起伏的新参数——地形起伏度.藉助傅抱璞公式和地形起伏度计算山区全年陆面蒸发量的误差,一般小于4%,个别最大误差达13.1%,平均误差为5%. |
英文摘要: |
On the basis of meteorological and hydrological data in seven catchments in Yunnan Province,three formulae [Eqs.(3),(5),(6)] calculating the evaporation from land surface are tested and compared.It is found that Fuh's formula[Eqs.(6)] is the best one among them.A new parameter U,undulation of topography [Eqs.(10)],is defined.By virtue of Fuh's formula and the undulation of topography,the evaporation from land surface in the mountainous country can be calculated without much error. |
