摘要
森林资源二类调查一般每10年进行1次,年度数据更新是林业部门迫切需要解决的技术难题。基于小班数据与遥感技术相结合,采用面向对象的方法对林地小班数据进行空间信息的更新。以香格里拉的虎跳峡镇为例,以2006年二类调查小班数据为基础,利用2008年12月SPOT5影像探讨了林地变化信息提取。结果表明:与传统变化检测技术方法不同,该方法可实施对森林资源二类调查数据空间信息的快速更新,客观地反映林地的变化信息,可以满足森林资源管理部门对森林林地变化信息快速提取的需要。
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.
