CALCULATION AND RATIONALE FOR GROWING FOREST CROPS IN SANITARY-PROTECTIVE ZONES OF TOMSK PETROCHEMICAL PLANT

The object of study is the sanitary protection zone within a kilometre around the Tomsk Petrochemical Plant. The forest fund lands occupy 646 hectares, 4 hectares of which are the artificial stands. Unforested land and sparse forests of pine occupy 2.6 hectares. There are no non-forest lands. The main forest-forming species in the TPP buffer zone are silver birch, which occupies 43.9% of the forest, andaspen -37.5%. Conifers make up 18.4% of the total, including pine - 10.4%, spruce and fir - 4.0% each. Willow tree predominates on the area of 1.3 hectares. But for the softwood and hardwood stands cedar and larch are found. The TPP sanitary-protective zone is not selected and framed timely. Forests around the enterprise entered the sanitary zone of the Siberian Chemical Complex, which includes the entire territory of Kuzovlevo timber cottages from the northern border of the town to the distance of 18 km. Forests around TPP are practically without an owner. Estimation of costs of felling for reformation and renewal, as well as planting in the buffer zone and near-plant territory can be used for planning costs of reconstruction works, improving stability and longevity of plantings of the TPP buffer zone. We discussed in detail issues relating to the calculation and substantiation of planting in the sanitary protection zone of the Tomsk Petrochemical Plant, species composition and age structure of plantations in the sanitary protection zone, buffer zone plantings distribution by value class and plenitude, distribution of plants in the buffer zone in groups of forest types. The costs of felling and planting forests in the sanitary zone were calculated. It is proposed to divide the territory of the designed buffer zone into two functional areas distinct in purpose and use: sanitary protection and near-plant. The composition of the sanitary protection functional area includes all existing vegetation. The composition of the near-plant is decorative and protective landscaping in front of office buildings and entrances, as well as open areas, which are designed for creation of new protective plantations. Estimation of costs of felling for reformation and renewal, as well as planting in the buffer zone and on the near-plant territory was performed at an average cost of similar works in the Department of Urban Forests Department of Real Estate Administration of Tomsk and Tomsk forestry. As the project is social and aims at improving the state of the object, it will not bring any real profit and will be based on the costs that will be recompensed by the increase of the stability of stands and the improvement of the environment around TPP.
