Forest resources management inventory is generally conducted every ten years,and the annual data updating is a technical problem that the forest resource management department urgently needs to solve.This study uses object-oriented approach to update the spatial informationof forest sub-compartment data based on the combination of the sub-compartment data and remote sensing technology.Taking Hutiaoxia township in Shangri-La as case study,this paper chooses the SPOT5 image in December 2008 and the forest resources management inventory data in 2006 to extract the forest land change information.The results show that the method can implement the rapid update of the spatial information of the forest resource management inventory data,objectively reflect the change information of the forest land,and meet the needs of the forest resource management department for the rapid extraction of forest land change information.
