遥感生态指数 （Remote Sensing Ecological Index）是一种基于 遥感 技术对 生态 系统进行监测和评估的 指数，它通过对地表反射光谱数据的分析，反映出 生态 系统的植被覆盖程度、植被生长状况、土地 利用 类型、土地覆盖变化等 生态 环境信息。 遥感生态指数 通常采用 遥感 影像数据来 计算，包括多光谱影像、高光谱影像、雷达影像等。 常用的 遥感生态指数 包括植被 指数 （Vegetation Index）、归一化植被 指数 （Normalized Difference Vegetation Index，NDVI） …

2013年9月6日 · 1) 归一化木质素指数（Normalized Difference Lignin Index——NDLI） NDLI是用来估算植被冠层木质素的相对含量，应用生态系统分析和检测森林的枯枝落叶层。 其计算公式为：

2020年9月26日 · A recently-proposed Normalized Difference Laten Heat Index (NDLI) and Normalized Difference Vegetation Index (NDVI) are utilized and compared to derive LULC, in particular, water bodies. Validation is based on reference datasets collected from Google Earth and field survey.

Normalized Difference Lignin Index (NDLI): The NDLI is designed to estimate the relative amounts of lignin contained in vegetation canopies. High reflectance at 1754nm is largely determined by the lignin concentration of leaves, as well as the overall foliage biomass of the canopy.
