| 摘 要： | 利用地面湍流观测资料估算了黑河实验区几个典型下垫面的局地地表动量粗糙度，与卫星观测Landsat TM资料相结合得到了由标准化差值植被指数(NDVI)计算地表动量粗糙度的经验关系式，进而估算了实验区夏季和近冬季的地表粗糙度的区域分布，并对所得关系式进行了合理性检验。

| Abstract: | Data collected at several observation sites of HEIFE were used to estimate local roughness length for momentum. Combining of remote sensing data, an experienced formula for calculating roughness length for momentum was obtained from normalized difference vegetation index I NDV .Further, area roughness length for momentum for summer and early winter were estimated by this relationship, which was validated by measurements in the field. |

| Keywords: | roughness length for momentum vegetation index area distribution |
