| 摘 要： | 为了用气候模式研究冰雪圈变化的气候效应，我们在已经发展的土壤－植被－大气模式基础上，考虑积雪改变表水文和反照率的参数化，建立了包含雪盖问题的陆面过程模式。利用中国西北黑河地区的ＨＥＩＦＥ实测气象和辐射资料，检验了模式对大气降雨和降雪的响应，结果表明，该模式描写的各种物理过程合理，一些可观测要素（如地面温度和地表净辐射通量）的演变特征与实况相当一致。

| Abstract: | Having considered the snow-cover process,we developed a new version of the land-surface process model from the existing soil-vegetation-atmosphere model The new model describes additionally two major effects of snow-cover:the large reflectivity of solar radiation due to the high albedo of snow-surface and the lagged soil hydrological impact due to snow-melting A few experiments were designed against the meteorological and the surface radiation data observed during the HEIFE project,which was carried out at the Heihe region,in Northwestern China The modeled processes forced by atmospheric precipitation (both rainfall and snowfall) seem quite reasonable Some modeling elements such as the surface soil temperature and the surface net radiation coincide well with the observations |
