The aim of this study was to perform an analysis of the optimality of the landscape structure of the Republic of Lithuania. Various scientific methods were used in the study, namely: comparative, grouping, analytical, statistical data, graphical representation analysis. After calculating the formulas, the ratio of relatively natural and cultivated land in Lithuania and counties was determined, the relative deviation of the landscape structure from the optimal value of the ratio was estimated and the optimality class was determined. The article presents an analysis of the changes in the natural, anthropogenized and anthropogenic landscape of the Republic of Lithuania during the time period between the years 2002 and 2020. It was found that in the analyzed period the area of natural landscape increased by 4.63%, that of anthropogenic – increased by 7.08%, that of anthropogenized - decreased by 36.34%. Assessing the structure of the country’s landscape, it can be seen that in 2020 the largest part of the country’s landscape was occupied by anthropogenized landscape (55.79%), the smallest – by anthropogenic landscape (5.65%), and the natural landscape accounted for 38.56% of Lithuania’s territory. Calculations were also performed, which established that the ratio of relatively natural land and cultivated land in Lithuania Rns = 1.43. After estimating the relative deviation of the Republic of Lithuania from the optimal ratio value (Dr), it was obtained that Dr = -1.14, which means that the country’s optimality class is B1. |
