Abstract The hydromorphological investigation and classification of streams in mountainous areas of Beijing was conducted with river bed, bank, riparian zone, flood land, etc. as main objectives. The hydromorphology of 567 streams in mountainous areas of Beijing is divided into five classes: high (Ⅰ), good (Ⅱ), moderate (Ⅲ), poor (Ⅳ), and bad (Ⅴ). The results showed that the total length of the main streams was 4258km and percentage of the class Ⅰ to Ⅴ was 64.85%, 14.02%, 9.56%, 8.76%, and 2.81%, respectively. Streams of classes Ⅰand II together accounted for 78.87% of the total length. The results provide important reference for the hydromorphological and ecological restoration and eco-cleaning of small watersheds in Beijing or even the whole country.
