Objective: To make clear the current situations of wild medicinal plant resources in Xinbin County

and put forward suggestions for the development of traditional Chinese medicine (TCM) resources and the protection of medicinal resources in this area. Method: The survey was conducted through literature consulting and sample plot survey in the survey pattern of representative area-sample plot-sample set-quadrat. In addition

the reserves of medicinal materials were calculated by using the reserves function in relevant technical schemes. Result: A total of 36 plots were surveyed

including six representative areas

namely grasses

meadows

shrubs

coniferous forests

broad-leaved forests

and coniferous and broad-leaved mixed forests

which covered the whole Xinbin County. The investigation involved 536 wild medicinal plants

which belonged to 100 families

including 76 species of asteraceae

52 kinds of key medicinal herbs

and 31 kinds of special medicinal herbs. On the basis of the classification between key medicinal herbs and special medicinal herbs based on their efficacy

the results showed heat-clearing drugs and exterior-relieving drugs as the majority. According to the calculation of staple herbs

Schisandrae Chinensis Fructus

Dryopteris crassirhizoma

Asarum sieboldii radix and rhizoma and other key and special medicinal herbs had larger reserves. Six new herbs were found in Liaoning Province

in which Adiantum flabellulatum was originally produced in Taiwan and now found in Xinbin

Liaoning Province. And medicine bases within the county were also surveyed

including Ganoderma

A. sieboldii radix and rhizoma

Schisandrae Chinensis Fructus and other authentic herbal medicine cultivation bases. Conclusion: Xinbin County has rich medicinal plant resources. Through the fourth census of TCM resources

Xinbin County's wild medicinal plant varieties and reserves were clear

which provides the basis for the further development of TCM cultivation industry and the promotion of Xinbin County's TCM economy.
