Abstract: Three different methods, principal component regression method, partial least squares method and stepwise regression method are used to establish the volume inversion model based on the satellite image of ZY-3. The stepwise regression model is the optimal model by comparing the accuracy of different estimation models, and the relative accuracy is 95.2%, which meets the needs of forestry investigation.

Key words: ZY-3 image, volume, estimation model, model accuracy
