Summary: To define the degree of the environment changes influence on the tree growth the radial increment in common pine in the area of Krasnoyarsk HPS and Divnogorsk was investigated. Using Chaile and Van Vika techniques the diagrams of value change of the radial increment logarithm were constructed. Results of data processing have shown, that for the trees growing in the city, the synchronous decrease (reduction) of the increment expressed in a various degree after 1958 (in the period of the most intensive construction of the city), in this or that measure restored by 1970 (when the general development of the city had been finished) is shown. The negative angle of taper of linear model of trees in community in the area of the low reach of Krasnoyarsk HPS, testifies that changed microclimatic conditions after erection of the dam have resulted in delay of grows.
