黄河流域湖泊富营养化评价数据集（2020年）

该数据集为黄河流域面积大于10km2的典型湖泊的富营养化评价数据。本数据集基于Landsat-5,7,8系列卫星反射率数据开发了一种藻类生物量指数（Algal Biomass Index, ABI）来反演内陆湖泊的营养状态。基于浑浊水体指数对湖泊水体像元进行分类后，分别构建面向藻类生物量的营养状态指数反演模型。 该数据集包含1个excel表格文件，03-黄河流域湖泊2020年TSI指数数据集.xlsxThis dataset is the eutrophication assessment data for typical lakes in the Yellow River Basin with an area greater than 10 km². An Algal Biomass Index (ABI) was developed for this dataset based on the reflectance data of the Landsat-5, 7, and 8 satellite series to retrieve the trophic state of inland lakes. After classifying lake water pixels using the turbid water index, trophic state index retrieval models targeting algal biomass were constructed respectively. This dataset includes one Excel spreadsheet file named "03-Yellow River Basin Lakes 2020 TSI Index Dataset.xlsx".
