摘要: 以TM影像为数据源,以贵州省罗甸县为研究区,首先利用面向对象方法和植被光谱信息提取常绿植被,进而根据不同植被光谱曲线提取常绿阔叶植被,然后结合桉树生长的海拔、坡度、土壤、土层厚度等环境特性提取桉树信息,结果表明,提取桉树信息准确率达到86.67%。可见,基于面向对象方法,利用植被光谱信息和树种生长环境特性提取单一数据信息具有可行性。通过本文的研究,以期对其他树种信息的提取提供借鉴。

Abstract: With TM image as the data source,Luodian county as the study area,the object-oriented method and the vegetation spectral information were used to extract the evergreen vegetation data and according to the different vegetation spectral curve to extract the evergreen broadleaf vegetation data,and then,to extract Eucalyptus data on the basis of the growth environment characteristic of Eucalyptus,such as DEM,slope,soil,soil thickness,etc.The results show that the accuracy of Eucalyptus data is 86.67%.Using object-oriented method,the vegetation spectral information and the growth environment characteristic of tree species to extract the information of single data is feasible,which has demonstrative value for the extraction of other tree species.

Key words: TM, Luodian county, object-oriented, Eucalyptus
