| 摘 要： | 以甘肃景泰县的八道泉等3个乡镇为研究区,以2000年的Landsat-7ETM+遥感资料(多光谱波段空间分辨率为30m×30m,全色波段为15m×15m)作为信息源,以2000年甘肃景泰县的土地利用及森林资源地面调查数据为参考,分别采用目视解译和人机交互式解译两种方法,对研究区土地利用及森林类型进行了判读分类,并与2000年的地面调查结果对比,对两种解译方法进行了精度分析和综合评价。

| Abstract: | This study interprets and classifies land use and forest types in 3 sample townships in Jingtai County of Gansu Province,using Jingtai Landsat-7 ETM of Year 2000 + RS material (multi-spectrum bands,spatial resolution of 30m×30m,panoramic bands of 15 m×15m) as data source,taking ground survey data of forest resources and land use in Jingtai County of Year 2000 as reference,and alternating two methods of visual interpretation and human-computer interactive interpretation.Comparing with the result of ground survey data of Year 2000,the paper further analyzes accuracy and conducts integrated evaluation of the two interpretation methods. |
