Abstract:: The slopes in the three gorges dam and Yichang city were taken as the investigation objects，and the typical sampling method was used.The number of investigated slopes was 51；the number of samples was 192.The statistics about the basic situations of these slopes were made，the slope greening effects were evaluated，the species quantity characteristics，structure，composition and configuration mode of slope greening plants were analyzed.The results indicated that the slope greening effect was fairly good overall in the surveyed area，and the very good and fairly good evaluation levels accounted for 60.7% of all surveyed slopes；there were 40 species of common slope plants in this area，and they included 23 species of herbs，7 species of lianas，10 species of shrubs；the exotic species accounted for 50% in herbs；the levels of diversity of the herb layer and shrub layer were obviously higher than the liana layer′s；there mainly were three kinds slope greening plant configuration mode in this area,herb type，liana-shrub type，shrub-herb type；and the shrub-herb type was most used.At last，the problems existing in the ecological slope protection were discussed and the countermeasures were put forward.
