【摘要】 分别利用经验模型和混合光谱的线性分解模型计算了滇池水质的悬浮物分布,得到不同时相的滇池悬浮物污染分布图.结果表明混合光谱的线性分解模型在水质遥感应用中可以充分利用遥感影像的多光谱数据,克服经验模型的时空局限性,在内陆湖泊的水质参数提取应用中具有通用性.更多还原

【Abstract】 The suspended solid concentration of Dian Lake was proposed by means of empirical model and linear spectral unmixed analysis.The regions of the various suspended solid concentration were extracted from the TM images by using the methods above,which gets sound results.It demonstrates that the linear spectral unmixed analysis model can utilize the multi-bands of RS images and overcome the spatio-temporal obstacles of empirical model,so it can get a wide application in inland lake detecting and monitoring.更多还原
