Evaluation method for ecological adaptability of tobacco leaves

The invention discloses an evaluation method for the ecological adaptability of tobacco leaves. The evaluation method comprises the following steps: (1) sampling in different regions and detecting and calculating chemical component indexes of a tobacco leaf sample; (2) establishing and calculating availability indexes of the sample; (3) classifying to map availability index statistical results of the sample to domains of different regions, so as to obtain an availability index distribution map; and (4) according to the availability index distribution map, evaluating the ecological adaptability of the tobacco leaves. According to the evaluation method, one type of scientific and reasonable tobacco leaf quality evaluation indexes can be evaluated; and the availability index distribution map is combined to visually and quantitatively compare availability difference of the tobacco leaves in the different regions, so that regional tobacco leaf quality characteristics can be known very well and references are provi
