摘要
利用ＥＰＰＬＥＹ紫外辐射仪测量了６种下垫面对紫外辐射的反射率。初步结果是：（１）裸地、水泥地、草地、砂子和黑士的紫外反射率分别为２．４％，６．７％，２．１％，４．２％和６．６％，而新雪的紫外反射率为８３．５％。（２）紫外反射率均小于太阳总辐射的反射率，尤其是前５种下垫面。（３）紫外反射率的日变化与太阳总辐射反射率的日变化相似。
This study makes use of EPPLEY's ultraviolet radiometer to measure the albedos of ultraviolet radiation(UV) on six kinds of underlying surface. The primary re-sults are presented as follows: (1) The albedo of UV-radiation is 2.4% for bare soil, 6.7% concrete, 2.1% grassland. 4.2% sands,6.6% black soil and 83.5% new snow surface , respectively. (2) The UV-albedos are smaller than those of total solar short-wave radiation, espccialy for previous five kinds of underlying surface , namely. except for snow. (3) The daily curve of UV-albedo is similar to albedo of total solar short-wave radiation.
