Multi-scale evaluation of ecological restoration effects in the riparian zone using Landsat series images from 1980 to 2019

Quantitative evaluation of ecological restoration effects (EREs) is essential to provide operational feedback and implement adaptive management for future riparian restoration. This manuscript aims to develop a multi-scale evaluation method of EREs based on remote sensing observations, which uses th...
