Abstract

Abstract: Monitoring on the spatial and temporal distribution of chlorophyll a in coal mine subsidence area is always weak and difficult.Hyperspectral remote sensing technique offers timely，up-to-date，and highly accurate information for sustainable and effective management of this special water area.An overview is provided on the achievements of Hyperspectral RS applications in monitoring water chlorophyll-a and concludes the challenges of using this technique into coal mine subsidence area.And then，the main challenges are analyzed and some prospects about further studies are inferred.

Key words: Coal mine subsidence area, Hyperspectral remote sensing, Chlorophyll-a, Monitoring
