The current state of the forest belts in the Penza region can be described as unsatisfactory: some areas have been lost, others need to be restored. In this regard, considering the importance for agricultural produc-tion, it is necessary to monitor the condition of the forest belts and assess the impact of their reclamation on the productivity of agricultural crops. The purpose of the work is to evaluate the reclamative effect of field pro-tection forest belts on the productivity of crops in a separate subdivision of the educational and experimental farm "Ramzai" (Mokshansky district of Penza oblast) using GIS technologies. Based on the results of visual interpretation, the scheme of coverage of arable land by reclamative zones was created, their areas and crop yields were determined. When evaluating the coefficients of protective forest cover (PFC) and territory protec-tion (TP), it was found that the value of PFC corresponds to the normative values for the forest-steppe zone, and the value of the TP coefficient indicates insufficient protection of arable land. The results of the calculation of changes in gross yield show that on average over two years, its value of cereals and legumes increased by 4.28%, that of sunflowers by 2.71% and that of forage crops by 5.55%, which is due to the influence of the for-est reclamation. However, in the educational and experimental farm "Ramzai" there are plots where the in-fluence of forest belts is completely or partially absent, which indicates the need to develop and implement projects for the forest land reclamation.
Keywords: geo-information technologies, forest reclamation, forest belts, yield, gross harvest.
