Abstract: Information extraction for dominant tree group types is difficult in remote sensing image classification, howevers, the objectoriented classification method using high spatial resolution remote sensing data is a new method to realize the accurate type information extraction. In this paper, taking the Jiangle Forest Farm in Fujian Province as the research area, based on the Quickbird image data in 2013, the objectoriented method was adopted to identify the farmland, shrubherbaceous plant, young afforested land, Pinus massoniana, Cunninghamia lanceolata and broadleave tree types. Three types of classification factors including spectral, texture, and different vegetation indices were used to establish a class hierarchy. According to the different levels, membership functions and the decision tree classification rules were adopted. The results showed that the method based on the objectoriented method by using texture, spectrum and the vegetation indices achieved the classification accuracy of 91.3%, which was increased by 5.7% compared with that by only using the texture and spectrum.
