中文摘要:

      传统的水深测量方法是利用测量船上安装的测深设备和定位设备测出水域各点的水深。用遥感方法进行水深反演,基于OLI遥感影像对错戳龙错盐湖进行水深反演研究,确定OLI4波段是研究错戳龙错盐湖遥感水深反演的最佳波段,建立了此盐湖的水深遥感模型。经过对遥感数据和实测点数据的回归分析,建立了拟合方程。根据拟合方程对水深进行反演,反演结果与实测结果基本一致,从而证明了遥感测水深方法的快速有效性,弥补了传统实测水深方法的不足。

英文摘要:

      :Traditionally, the method of defining water depth is using the sounding device and pointing device.In this paper, the method of remote sensing is used to define water depth in Cuochuolong lake. Based on the OLI remote sensing image, it can be seen that OLI4 is the most suitable band to define the water depth in Cuochuolong lake. Through building the retrieval model of water depth in Cuochuolong lake, and regression analysis of remote sensing data and the actual measured point data,a fitting equation was established and used to calculate the water depth. The results show that actual measurement are basically same with the results from inverse method.It is proved that remote sensing can be used to define the water depth effectively and it can be used to overcome the shortages of the traditional.
