中文摘要:
      地表特征和下垫面物理性质在时空分布上的差异,造成地表能量分布的不均,地球表面的半球反射在气候领域是一个非常重要的参数,它在地-气能量交换中决定着能量在地气之间的分配比率。反照率随地表覆盖类型的变化具有很大的差异,而这往往是形成区域小气候差异的原因。文中通过统计和双向反射模型,应用NOAA14-AVHRR数据并结合地理信息系统,反演计算了1997年中国月平均反照率的分布,并对结果做了分析检验。
英文摘要:
      The interactions of at mosphere, ocean, rock, glacier and creature lead to the global clim ate change. Mean while, the activity of human being has changed the natural structure of land surface and the inherent balance of at mosphere. All these not only have affect on the global environment change, but also bring forw ard more strict requirement to GCM. Land surface is composed by the earths surface feature with different configurations and physical character istics. Every kind of earths surface feather has individual fashion of energy distribution and mass exchange. Because of violent change with time, the earth's surface feathers seriously affect equilibrium of energy, momentum and mass between the earth's surface and atmospheric layers. Practically, the distribution of land-surface category is irregular and takes on horizontal anisotropy. When difference is very large between land-surface and surroundings, local especial micro-climate is created. Though turbulent convection of at mospheric layers, it affects large-scale environment change, for vegetation, this point is even more obvious.
