摘要

In situ reflectance measurements and Landsat satellite imagery have been used to develop an optical classification scheme for alkaline-saline lakes in the Eastern Rift Valley. The classification allows the ecological state and consequent value to Lesser Flamingos to be determined using Landsat satellite imagery. The classification scheme was able to differentiate six classes - low phytoplankton biomass, sediment dominated waters, microphytobenthos, high biomass cyanobacteria, cyanobacterterial scum and bleached cyanobacterial scum - with a classification accuracy of 77 % when verified against in situ measurements. Classified imagery and timeseries showed the different ecological behaviours of these complex systems and highlighted the importance to flamingos of the food resources offered by highly remote Lake Logipi.
