米脂泉家沟土地专题制图中1:1万彩红外航片影象信息的利用

本文探讨了1:1万彩红外航片用于黄土高原丘陵沟壑区编制几种综合治理遥感监测土地专题图的实践。对土地类型、土地利用现状和坡度分级分类原则，影象判读标志和成图精度与SPOT和TM多时相影象利用效果作了分析对比。实践证明，该手段对微地貌不同立地类型判读精度在95%以上；林地类型影象判读精度在80%，不同治理措施判读>95%，农地及牧草地在75%。制图效率高于常规的3—4倍。1:1万彩红外影象直观地反映了各种景观要素之复合与叠加，是小流域监测专题制图的一种先进有效手段。

The Date From 1:10000 Colour Infrared Aerial Photo Used for Mapping Special Chart of Land,Quanjiagou, Mizhi County

1:10000 colour infrared aerial photo used in working out different special chart.of the land remote sensing inspection in comprehensive control of the loess plateau hilly and gully area has been probe in this article.It commpared land classification, Land utilization current situation and the regulation of the slope gradient graded, the mark of the "Read with film", and charting precision with utilization effect of the more temporal pictures stop and TM.It is proved by facture that the precision of reading is above 95% in micro landscape with different vertical type.To the forest land it is 80%, to different control measurements above 95%, tillage and grass land is in 75%.Charting efficiency is 8—4times higher than common.1:10000 colour infrared photo reflects directly the compound and alternate of the different landscape.It is an advanced efficient measurement used in special chartihg for a small (river basin) valley inspection.
