Abstract

The content of chlorophyll in leaves of tree species naturally growing on devastated lands was studied- Ash-leaved maple (Acer negundo L.), Black locust (Robinia pseudoacacia L.) and Silver Birch (Betula pendula Roth.) were investigated. The analysis of the obtained results showed that in trees naturally growing on devastated lands at Petrovsky iron ore waste rock dumps the content of chlorophyll in leaves was less than in the control plot: by 35-65% in Ash-leaved maple, by 25-52% in Black locust- This resulte indicates difficult ecological conditions of these devastated lands. The content of chlorophyll in the leaves of Silver Birch, only on the plot V is statistically significantly lower than the control values. It is shown that concentration of chlorophyll decreases non-linearly with the increase in the level of pollution in comparison with control values. The results obtained can be used in future to develop a method for reclametion and restarution of devastated lands, using the example of of Petrovsky waste rock dump
