摘要
卫星遥感的应用对了解尺度为１０￣４ｋｍ￣２的陆面特性及地一气间能量和水分交换过程具有不可缺少的重要意义。在“黑河地区地气相互作用野外观测实验研究”（ＨＥＩＦＥ）大量地面观测资料的基础上，介绍了引入ＬａｎｄｓａｔＴＭ等卫星遥感资料进行复杂地表陆面过程分析的基本方法；并以夏天一个景的ＴＭ资料为个例，分析了整个“黑河实验区”的地表反射率、植被指数以及地表温度和能量平衡各分量的分布及定量统计特征，这种分析为复杂下垫面中尺度模式参数化方案的建立以及模式预报结果的检验提供了坚实基础。有关方法仍处于发展的初始阶段，对此做了讨论。
To reach the goal of a better understanding of the process of land surface-atmo-sphere interaction at an areal scale in HEIFE,the utilisation of satellite remote sensing isindispensable, Based on the field observation of HEIFE,the basic method with the aid ofsatellite remote sensing data such as Landsat TM etc,to analyse the processes in the het-erogeneous landscape was intruduced in this paper. As a case study a summer scene of TMwas used to formulate a set of maps revealed some quantitative significant land surface pa-rameters. The analysis forms a sound basis to set a parameterization methodology ofmesoscale model over complex terrain and test the prediction results about the model.Thistechnique is still in a developing preliminary stage,it was also discussed in this paper.
