Fourth National Survey of Traditional Chinese Medicine Resources in Fengcheng, Liaoning Province

Objective: To explore the current conditions of material medica resources through the Fourth national survey of traditional Chinese medicine(TCM) resources in Fengcheng, Liaoning Province, in order to provide a reasonable basis for the protection and development. Method: The survey was conducted according to the technical scheme of the Fourth National Survey on Chinese material medica resources. The survey method of representative area-sample area-quadrat set-quadrat was adopted for wild resources of medicinal plants. Six representative areas, namely grass, meadow, shrub, coniferous forest, broad-leaved forest and theropencedrymion, were selected in the survey. Result: Totally 36 sample plots, approximately 5 000 medicinal plants and 161 medicinal ancient trees were surveyed, including 7 species that had not been reported in Liaoning Province; Arisaema amurense was first found in Fengcheng, whose leaflets was covered with whitish marks, and which was recorded in the Flora of China; and an undetermined Pulsatilla was found at the top of Baiyun Mountain. Conclusion: The general surveywork of TCM in field was completed. We found that Baiyun Mountain in Fengcheng is a special mountain gathering both Changbai flora and North China flora, with a high vegetation coverage rate and large number of plant varieties. A natural reserve area is suggested to be established to better protect rare medicinal plant resources.
