2015、2019黄河三角洲（山东省垦利县）30m盐渍化分布数据集

本数据是在ArcGIS、ENVI环境下，利用Landsat 8 OLI遥感影像数据，通过辐射定标、大气校正、几何精校正、裁剪等预处理，提取地物的特征参量，择优选取盐分指数（SI）、地表反照率（Albedo）构成SI-Albedo特征空间，对模型参数正规化处理，进一步得到区域内盐渍化分布反演图。

This dataset was developed using Landsat 8 OLI remote sensing imagery, with processing conducted in ArcGIS and ENVI software environments. Preprocessing operations including radiometric calibration, atmospheric correction, geometric fine correction, and clipping were first performed to extract feature parameters of surface features. Then, the Salinity Index (SI) and Surface Albedo (Albedo) were optimally selected to construct the SI-Albedo feature space. Following the regularization of model parameters, the inversion map of salinization distribution within the study area was finally generated.
