摘要：在土地調查中，遙感圖像存在同譜異物和同物異譜現(xiàn)象。文章以青島市不同區(qū)域為研究對象，對其地類進行拍攝及區(qū)分紋理，制作地類圖冊，建立地類樣本庫?；贏rcGIS Engine技術、GIS組件技術開發(fā)應用程序，以第三次全國土地調查為依托，文章構建了一個地類樣本庫可視化管理系統(tǒng)。

Abstract： In land survey， remote sensing images have the phenomenon of homogeneity and heterogeneity. This paper takes different areas of Qingdao as the research objects， takes pictures of the land types and distinguishes their textures， makes a land type atlas， and establishes a land type sample database. The developed software based on ArcGIS Engine technology and GIS component technology relys on the third national land survey， and the paper constructs a visual management system of land sample database.

Key words： ArcGIS， geographic sample base， management， analysis
