ANALYSIS OF LAND MANAGEMENT OF THE FOREST FUND

The relevance of the research is related to the priority attention of the state to the use of forests as the main reproducible natural resource in Russia. The aim of the research is to analyze the existing spatial division of forest lands. Objects: lands of the forest fund of the Tomsk region, divided into districts, forest areas and district forest areas on the principle of three-level hierarchical division. Methods: abstract-logical, analytical and mathematical modeling. The working hypothesis assumes that the area of forest plots depends on the value of the scale unit according to the power law, and the coefficient at the logarithm of the function reflects the range of changes in the scale dimension. For the first time, the problem of changing scale is used in relation to the analysis of land management in forest areas. Results. The hierarchical structure of the territorial division of forest lands is revealed. In general, the area of local forest areas in the Tomsk region varies between 282–2332087 ha. Univariate variance analysis of areas shows a low probability of a null hypothesis (less than 1 %). The desirability profile constructed at the next stage of the study revealed a critical value of the average area equal to 71255 ha, to which the plots correspond with a 63 % probability. The patterns of distribution of the total forest area by forest areas differ from the normal one. Its general average value is 175000 ha, the area of coniferous forests in forest areas – 6000 ha, deciduous forests – 11,000 ha. In general, the area of coniferous forests in forest areas does not exceed 8000 ha, deciduous forests are concentrated in the range of 4000–10000 and 16000–20000 ha. The distribution of wood stock is also heterogeneous. The total area of forests in forest areas is not evenly distributed, and its distribution is close to the lognormal model. The largest number of forest areas is concentrated in the range of up to 15000 ha. Very rarely there are large plots (more than 30000 ha). Fragmentation of coniferous forests is high. The modal size of the site is from two to four thousand hectares. Large areas of forest are quite rare. The distribution of deciduous forest areas is polymodal and is divided into three parts: up to 2000 ha, 4000–120000 ha, 14000–20000 ha, which indicates the presence of small and medium-sized forests, as well as large woodlands. One forest area is very large (more than 32000 ha). The total supply of liquid wood is concentrated in t
