THE REMOTE SENSING DISCRIMINATORY MARK OF THE RELATIONSHIP BETWEEN SEDIMENT SPACIAL DISTRIBUTION AND RIVER FLOW SPEED IN EROSION AREA OF RIVER ESTUARY

    摘要
  • 摘要: 通过对泥沙光学光谱特征和河口冲刷区水动力特征的研究和总结,分析了中巴地球资源卫星(China Brazil Earth Resource Satellite) CCD相机B1,B2和B3波段的太湖遥感图像,初步论证了入汇河流流速与冲刷区跨度的关系,以及遥感定量河口泥沙交换强度和动态反映冲积扇发育方向及强度的可行性,并提出了河口泥沙交换强度的判别标志。

     

    Abstract: Based on research and conclusion of the silt spectra feature and the water power of erosion in river mouth area, we analyzed remote sensing images of Taihu area showed in B1, B2 and B3 bands from China Brazil Earth Resource Satellite's CCD cameras. The results preliminarily demonstrated that there was relationship between the radius of erosion area and the speed of river inflow, and it is possible to use remote sensing method to quantitatively analyze exchange intensity of sediments in river estuary and dynamically reflect the development direction of alluvial fan. At the same time discriminatory mark for exchange intensity of sediments in remote sensing images is proposed.
