黄土丘陵区土地利用遥感制图研究

选用黑白全色航片、彩色红外航片、MSS 影像和 TM 影像资料,在黄土丘陵区进行土地利用制图的对比实验,对多信息源的资料特点、应用潜力和综合信息提取进行了探讨.结果表明,彩色红外航片是1:50000大比例尺土地利用制图的最优资料,TM 影像可满足1:100000土地利用制图的需要,其资料与航片结合也可进行1:50000土地利用制图及对原有1:50000土地利用图进行更新和修测.

Study of remote sensing mapping of land ues on Loess Hills

The experiments are about land use mapping on Loess Hills by remote sensing meth- ods.The characteristics,potentiality,multisources extractiom about remote sensing in- formatiom are disscussed,and the black-white aerial images,color infrared aerial im- ages,MSS images,TM images are chosen in this paper.It is shown that every remote sensing resource above has its own features when it is used in land use mapping.But in the Loess Hills,the best information of land use mapping at the scale 1:50 000 is color in- frared aerial image.TM images are chosen when the scale is 1:100000,and the mapping scale of MSS is 1:200000 only.The TM images in combination with aerial images can be used as land use mapping at scale 1:50 000 and its renewal.
