Method for identifying producing area of tea by using element content in the tea

The invention discloses a method for identifying producing area of tea by using element content in the tea. Spectroscopy analysis technique is used for determination and establishment of a tea element content database; based on the partial least squares, VBA code of EXCEL is used to establish a multielement content tea producing area discrimination model; through the determination of the contents of 21 elements in the tea, data is input into a prediction module of a piece of software for calculation; if a judgment value of a certain tea is greater than 0.8, the tea can be considered as belonging to the tea producing area, and otherwise the tea doesn't belong to the tea producing area. The analysis results of the invention are only decided by software prediction value, so as to rule out subjectivity and uncertainty of human judgment; and the method with high determination accuracy can be used to identify different teas from different producing areas and has a broad application prospect.
