| 摘 要： | 通过对五种不同水体提取指数模型(RVI,NDVI,NDWI,MNDWI,NDSI)的原理分析,结合具体实例(洞庭湖水域)进行水体遥感提取来说明五种方法提取水体的差异,从而确定在不同时期和不同用途时所采用最佳的水体提取模型。以洞庭湖水体富营养化监测为最终目的,由此确定了最佳水体遥感提取模型为MNDWI指数模型。

| Abstract: | The difference of the water extraction methods by using of the five different index models(i.e.RVI,NDVI,NDWI,MNDWI and NDSI) is studied through the analysis of the specific theory and the specific examples(Dongting lake areas) .So that help to choose the proper model which is determined for water extraction should be available in different time and for different purpose.The purpose of monitoring the eutrophication of Dongting lake areas is taken,so the MNDWI model was selected for water body extraction. |
