TM图像自应用于土地资源调查以来,对其应用潜力争议很大。鉴于此,本文以河北省南皮县为研究区,利用常规方法,分析、评价了TM图像在县级土地利用制图与农业分区中的应用效果,并与SPOT图像进行了对比分析。研究结果表明,利用TM图像进行县级土地利用制图与农业发展分区,可以得到令人满意的结果,借助TM图像包括中红外在内的多波段光谱信息的优势,可以达到SPOT多波段图像的应用效果。本研究为我国应用TM图像进行县级土地资源调查与制定发展规划提供了一个实例。

Since TM image is applicated in the land resource survey, many research results are different. In view of it, this research analysed and evaluated the applicated effects of TM image in the land use mapping and agiiculture development partition, and make the compared with the application of SPOT multispectral image, selecting Nanpi County of Hebei Province as the test area. The results indicated that the satisfying results can be got using TM image to make land use mapping and agriculture development partition. As the advantage of TM multispectral, it can be got that the similar results to SPOT image. This research provide a sample in order to make the land resource survey and development programme in TM image in our country.
