Evaluation of riparian condition of Songhua River by integration of remote sensing and field measurements

Abstract Riparian zone is crucial to the health of streams and their surrounding environment. Evaluation of riparian condition is essential to achieve and maintain good stream health, as well as to sustain ecological functions that riparian areas provide. This manuscript is aimed to evaluate riparia...
