利用SPOT卫片在黄土高原丘陵沟壑区进行土地利用现状调查的精度分析

APPLICATION OF SPOT IMAGE ON LAND USE INVASTIGATION IN HILLY-GULLY AREA OF LOESS PLATEAU

本文探讨了利用ＳＰＯＴ卫片进行黄土高原丘陵沟壑区县级（１：５００００）土地利用现状调查制图的可行性。从分类精度、制图精度等方面进行分析，提出在本区进行土地利用现状调查制图（１：５００００），可用ＳＰＯＴ卫片配合黑白航片作为调查信息源。另外，还讨论了利用ＳＰＯＴ卫片在本区进行某些土壤类型判别的可行性。

This paper is aimed at land use mapping technique with SPOT image to produce a Land use map at county level (1:50000)in hilly-gully area of Loess Plateau. A more suitable method was devised by the authors by using SPOT image together with black-white airphoto. This paper also deals with the classification of certain kinds of soils by the applications of SPOT images.
