| 摘 要： | 基于定量遥感理论和方法，将多光谱遥感数据和实测水质数据相结合，研究了水生态环境的空间分布，并对其进行了分析和评价．探讨了多光谱水遥感图像的处理方法和水质参数的数学回归模型，并以太湖水域的悬浮物含量为例，进行了回归分析．结果表明，采用遥感手段对水质进行监测是可行和正确的，由遥感数据得到的太湖水域悬浮物含量的空间分布也与太湖水域的实际情况相符．

| Abstract: | The paper presents a study of the spatial distribution of water environment on the basis of quantitative remote sensing theory and methods and multi-spectral remote sensing data and water monitoring data on the spot, and an analysis and estimation of the distribution data. The processing method of multi-spectral remote sensing data is presented and the regression model of water quality parameters is derived. Based on a case study of Lake Tai, the regression model of suspended sediment concentration is set up. The result shows that it is feasible to monitor water quality with the method of remote sensing, and the spatial distribution of suspended sediment concentration of Lake Tai obtained from the remote sensing data agrees well with the data in situ. |
