摘要

在韭园沟小流域选择试验样区，采用地理信息系统等技术，基于不同分辨率遥感影像开展了水土保持措施等信息提取和精度分析．结果表明，在黄土丘陵沟壑区第Ⅰ副区，开展梯田、沟台地、疏林地、未成林造林地遥感监测的影像分辨率应优于2.5m，开展坡耕地、坝地、退耕荒草地遥感监测的影像分辨率宜优于2.5m，开展天然草地遥感监测的影像分辨率可选择2.5m，开展林草植被遥感监测的影像分辨率宜优于10m．

Abstract

A number of test areas were selected in Jiuyuangou small valley. Based on different resolution remote sens-ing images

features of soil and water conservation measures were extracted using GIS technology. The results show that in the first subzone of hill-gully zone of Loess Plateau

the image resolution must be higher than 2.5 m to ap-propriately extract the features of terraces

platforms

sparse forests

and undeveloped planting forests; the resolution level should be higher than 2.5 m for accurate extraction of slope farmland

dammed valley

and grassland converted from farmland; the image resolution level can be higher than or equal to 2.5 m for natu-ral grassland. The resolution level should be higher than 10 m for forest-grass vegetation.
