摘要
以试区1986经相嵌纠正的1/5万正射投影航片为基本遥感信息源,结合1984年试区TM2、3、4波段假彩色合成卫片,采用目视判读解译方法。综合分析与逻辑推理相结合,建立判读解译标志,编制解译检索表,完成试区土地利用与草地资源调查与制图,定性、定位、定量准确。遥感技术用于坝上土地及草地调查制图,具有速度快、省工时、成本低、精度高的效果。
The main source of remote sensing information was based on a mosaic-rectified 1: 50000 ver- tical projection aerial photograph of study region in 1986. Combined with band 2, 3 and 4 TM satel- lite images of the study region in 1984, the sight interpretation method was used to set up interpreta- tion keys. The interpretation index was worked out base on comprehensive analysis and logic reason- ing. The qualitative, quantitative and orientation survey and mapping of land use and grass resources of the region have been finished. The application of remote sensing on land and grass resources in- vestigation and mapping has its advantages on fast speed, less work, low cost and high precision.
