| 摘 要： | 基于降雨径流模型确定水电站地址勘察已成为水资源评价中的一个重要课题。随着卫星技术的发展，遥感、地理信息系统能够快速地确定水电站地址勘察。选取位于云南省中部滇中盆地地区澜沧江流域作为研究区，利用遥感和地理信息系统技术，从数字高程模型角度出发，确定了流域尺度、流域边界和最小面积、平均高程、流域平均坡度等水文信息。运用分辨率为2.5 m的IRS-P5立体卫星数据导出数字高程模型。该数字高程模型用于生成盆地的流向和流量累积图。通过对这些图像的分析得出了综合排水网；利用地形资料，包括流域面积、平均流域高程和降雨资料的有限点观测值，推导出整个流域的回归模型，使用平均面雨量计算其雨量分布图，结合Kriging统计方法生成子流域验证这个回归模型，并给出了水电站地址勘察建设地点。

| Abstract: | The determination of hydropower station address based on rainfall runoff model has become an important issue in water resources assessment.With the development of satellite technology，remote sensing and geographic information system can quickly determine the address survey of hydropower stations.In this paper，the study area was located in the middle reaches of Yunnan Province，Yunnan basin basin，as the study area.Using remote sensing and geographic information system technology，from the point of view of digital elevation model，the hydrological information such as basin scale，watershed boundary，minimum area，average elevation and average slope of watershed were determined.Deriving DEM from IRS-P5 stereo satellite data with a resolution of 2.5 meters.The DEM was used to generate the cumulative flow and flow maps of the basin.Through the analysis of these images，a comprehensive drainage network was obtained.The use of terrain data，including the finite point drainage area，basin average elevation and rainfall observations，regression model was derived in the whole basin，using average rainfall to calculate the rainfall distribution map，combined with Kriging statistical method to generate sub basin to verify this model，and to give a survey of the construction site of hydropower station. |
