Detection of Decreasing Vegetation Cover Based on Empirical Orthogonal Function and Temporal Unmixing Analysis

Figure 6

Vegetation fraction map in Suqian City (a), Nanjing City (b), and Suzhou City (c) in Jiangsu Province. Vegetation endmember fractions in 2000, 2006/2002, and 2009 are shown as blue, green, and red channels. The dark areas mean no vegetation from 2000 to 2009. The blue areas mean vegetation cover in 2000, but with no vegetation in 2006/2002 and 2009, which clearly exhibits vegetation change processes. The whole area is the city and the red rectangles refer to central urban.
