| 摘 要： | 以2002年4月18日Landsat TM/ETM 多时相、高分辨率遥感数据为主要数据源,对黄河三门峡至小浪底区间暴雨致洪水文下垫面进行调查。通过遥感图像处理、结合常规资料和野外调查,在水文下垫面主要因子分类基础上,建立解释标志。采用人机交互方式提取研究区地貌、土壤、植被、土地利用等信息,在较短时间内得到黄河三门峡至小浪底区间下垫面基本情况,对提高该区间水文预报精度、缩短洪水预见期具有重要作用。

| Abstract: | An investigation was conducted on the hydrological underlying surface for rain-induced floods from Sanmenxia to Xiaolangdi in the mid-lower reaches of the Yellow River by means of the multiple time-phase,high-resolution remote sensing data of Landsat TM/ETM~+.Through remote image processing,in combination with conventional meteorological data and field surveys,based on the main factor classification,the indicators of factor interpretation were established.The information of topography,soil,vegetation,land use,etc.was derived in the man-machine manner and the basic conditions of the underlying surface for the area from Sanmenxia to Xiaolangdi can be obtained in a short time.These messages are useful for improving the hydrological prediction. |
