On the basis of ecological characteristics

the pine leaves damaged bypine moth were classified on five levels and their reflectance and chlorophyll con-tents were measured and analyzed in this paper.The results indicate that damageis becoming more serious

①the chlorophy11 content is down

②the reflectance at 550nm

the difference between the infrared shoulder reflec-tance and the lowest reflectance in red range

and the largest value of the firstderivative in red reflectance edge

all come down

③the reflectance at 630nm goes up

④blue shift of the red edge spectra and red shift of the chlorophyll reflec-tance peak are obvious。With the stepwize discrimination analysis

it was analyzed and was proved thatthe characteristic parameters of the fine spectra of the damaged pine leaves havestronger capability than the single-reflectance parameters in the three bands ofgreen

red and infrared for discrimination and classification of the damage

Thispaper also gave out a discrimination model for the damage forecast with the remotesensing approach。
