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.
