Abstract: The spectral feature of ground objects is the fundamental basis of remote sensing application research. The color plants application is widely concerned in the city landscape, and which plays an important role in constructing a color plentiful and distinct seasonal changing garden city. Hyperspectral data of the samples were acquired by using ASD Fieldspec 3 spectroradiometer,the samples were 10 species of color plants, including Ficus microcaba cv.Golden Leave, Alternanthera bettzickiana, Cordyline terminalis and so on in Shenzhen. The results of analysis showed that the reflection spectrum of red-leaf plant and purple leaf plant had a “red peak” value in the 600-650 nm, while in the 500-550 nm range the spectral reflection area of purple leaf plant was significantly greater than red-leaf plant. For the yellow leaf plant, the distinct waveband of reflection spectrum was 490-650 nm, and the spectral reflectance increased sharply at 490 nm, then the level kept more than 60% in the 550-650 nm range; the variance analysis showed that the spectral reflection area value of 500-550 nm was significantly different. Moreover, the cluster analysis result was consistent with actual color classification, so the value of Sλ500-550 could be used as a color distinct value of plant color.
