Puyang River is often affected by the flood disaster. However, herbaceous plants play a key role in control of soil erosion. In this paper, a field survey of species, relative coverage, abundance and relative height for herbaceous plants was carried out in the riparian area of lower reaches of Puyang River. The root densities of dominant plant species, enhancement values of anti-scourability by roots were studied. The results showed that:(1) Cynodon dactylon, Polygonum hydropiper, Phragmites australis, Miscanthus sinensis and Paspalum paspaloides were dominant in herbaceous plants; (2) roots with diameter less than 1 mm of 5 herbaceous plants mostly distributed in 0—30 cm soil surface layer, the root densities decreased with the increase of soil depth, and the relationship of them followed the index series relationship; (3) all the roots of 5 species had remarkable positive enhancement effects on soil anti-scouribility, and the intensified value of soil anti-scourability by root system of Phragmites australis was 14.16, 12.53 for Miscanthus sinensis, 5.39 for Cynodon dactylon, 5.01 for Paspalum paspaloides, and 4.41 for Polygonum hydropiper. In the experiment, it is suggested that these five herbaceous plants, especially Phragmites australis and Miscanthus sinensis, could enhance the soil anti-scouribility for protecting the riparian area of lower reaches of Puyang River.
