Abstract

Results of the comparative anаlysis of the state of larch plantations in the regions of Krasnoyarsk differing in the levels of air pollution are presented. The features of the structure of crown and the correlation structure of habitus signs and tree states observed in the regions with medium and high level of air pollution are shown. It is concluded that the sensitivity of correlation signs is higher and they are suitable to reveal changes that cannot be diagnosed with the help of the eye survey of tree state.
