In this work, an attempt was made to assess the possible change in the photosynthetic potential of the forests of New Moscow, depending on the degree of their remoteness from the territories with technogenic impact, based on the data of remote sensing of the earth. Because of constructing the time series of the spectral index NDVI, the value of the photosynthetic potential of homogeneous forest areas at different distances from the old borders of Moscow was estimated. Studies have shown that the average NDVI values of forests increase with distance from the borders with Old Moscow. The lowest NDVI values (0.70) are typical for forests located at a short distance from Moscow. In the central part of New Moscow, the index is 0.72, and the highest NDVI values (0.75) are observed within the settlements located in the south near the border with the Kaluga region.
