ALGORITHM OF FORESTLAND MASS CADASTRAL EVALUATION USING FOREST INVENTORY DATA

The relevance of the research is caused by the necessity of unite state cadastral evaluation method for forestlands in Russia. It is important for rational natural resources management, providing of fair fee for forestland use and for sustainable development of Russian forestry. The aim of the research is to make an algorithm of mass forestland cadastral evaluation by forest sites. Opportunity of its usage for the whole area of Russia should be provided by taking into account regional peculiarities of forest resources harvesting. Methods: discounting of cash flows from forest resources harvesting; regression analysis of dependence between forest inventory data and productivity of forest resources; geographic informational modelling using MapInfo; testing of normality distribution hypothesis for obtained results; algorithm application using MS Excel. Results and discussion. The authors have developed the algorithm of mass forestland cadastral evaluation. It makes possible to calculate cadastral value for both single forest site and whole forest district. Forest inventory data is used as basis for calculation. Algorithm can be modified by addition of discounted cash flows from forest resources harvesting which are special for particular natural zone. Method approbation is provided using forest inventory data of one of the Leningrad region forestry districts (considering regional peculiarities of forest resources harvesting). Obtained values of cadastral magnitudes (per unit) are normal law distributed. High values of cadastral value are spatially correspond to better forest sites.
