Abstract: A mathematic model was set up for estimating the organs-and plant economic production of Acanthopanax senticosus with selected function types and variants such as ground diameter (D) and plant height(H). The optimum estimation model was determined according to the correlation coefficient(r) and surplus standard variation(Sd). The effectiveness of estimation was different for various organs: Stem>Plant>Leaf>Root stem>Root>Leaf stalk.
