Abstract
The two coefficients for estimation of differentiating diversity of plant communities, proposed by A. P. Shennikov were considered: coefficient of dispersity and coefficient of variegation of addition. These coefficients are given in modern set-theoretic notation. Their connection with multiple-site measures of similarity and difference of communities’ descriptions, which are used to evaluate the differentiating diversity, was established.
