the formation time

representative scholars and monographs.The environmental ecology theory reflected the academic inheritance based on the holistic view which named"Tian Yao Ren He Yi (union of nature

herb and human)".Variety continuity and origin change theory

quality ecology theory

stress-effect theory and herb genomics theory reflected the academic thought innovation based on inheritance.This paper mainly elucidated the innovation theory of Daodi herbs

stated the core academic views and research contents

introduced the new techniques and new methods in the modern research of Daodi herbs

and analyzed the correlation and continuity between 5 theories.The innovation theories and related research systems would provide strong support for the origin of Daodi herbs and new germplasm breeding.Besides

we mapped the evolution of "Daodi herbs" names and also discussed and prospected the new problems

new demands and research thoughts in the research of Daodi herbs.
