| Ecological zoning of administrative districts in the Nizhni Novgorod region has been carried out on the basis of the anthropogenic pressure index ( J an). Eleven eco-economic indicators of the State Statistics were used to calculate J an. The cluster analysis was used to divide all districts into 4 different clusters according to their anthropogenic pressure indices. Most districts fell into the clusters with satisfactory and low anthropogenic pressure. |
