Abstract In this paper, a method for detecting the fast-growing plantation based on remote sensing is proposed, and the measuring of the distribution of the fast-growing plantation in large areas has been realized. This method is based on the cure trajectory extracted from the multi-year CBERS images. According to the characteristics of the electromagnetic spectra obtained during the period when the fast-growing plantation was cut down and the soil was turned up, the land used for fast-growing plantation can be extracted. The test in Leizhou City of Guangdong Province shows that the overall accuracy of the extracting method is 88%, which indicates that CBERS CCD images can be used to extract fast-growing plantation in large areas.
