In order to recognize the structure characteristics and development trend of urban herb plants,improve urban environment and enhance the level of urban virescence landscape,the herb plants in the Beijing zone are investigated through sampling and collecting specimens. The results show that there are 202 herb species belonging to 127 genera and 43 families within the fifth-circle road in Beijing city.Based on their usage, the herbs can be divided into three different groups:officinal, ornamental,edible plant. The 27 species that should be protected are those which have high important value,and its important value over 0.001,including coverage plants,vertical greenish plants,etc.
