535 METHODS OF INTERPRETATION OF AERIAL PHOTOGRAPHS IN FOREST INVENTORY AND MANAGEMENT IN THE USSR V.I. Sukhih, S.G. Sinitsin Ministry of Forestry, "Lesprojekt" Moscow, USSR The forest is the most important component of the biosphere. It is extremely significant for the national economy as well as for biological and social aspects. It is necessary to have data of forest resources for the proper operational management of forestry, for the planning of forest yield and for forecasting purposes. In the USSR the determination of forest resources and condition is the role of Forest Inventory and Management. Soviet practising foresters have accomplished much as far as forest inventory and forest mapping are concerned. They have estimated the whole stock of forest of the country, which occupies an area of over 1200 millions of hectares. The annual amount of work in forest inventory and management at present is 45 millions of hectares and is to be increased up to 50 millions hectares, thanks to the application of survey and aerial data, which are the technical base of modern forest inventory and management. The basis of estimation interpretation is the analytical method, which is based on the intensive analysis of all the factors affecting 'the character of the image of forest cover, as well as upon the knowledge of bio logical characteristics of the overhead cover and the structure of the over head cover. One of the first and important tasks is the division of the forest stock into homogeneous forest compartments, the total area of which varies from about 0,1 hectares to dozens of hectares. Without the use of aerial photographs the severance cutting of sites is needed every 125-500 meters depending on the category of forest inventory. The use of surveying materials permits one to refuse all the severance cutting or reduce its extent by three times and in this way, contours of most of estimation forest compartments can be determined on the base of aerial photographs interpreted in the laboratory and partially in the forest. The accuracy of boundaries of forest compartments is of great practical and economical importance, especially in the areas of intensive forestry, where forest compartments are rather small. For example, when the size of the forest compartment is about 1 hectare, a 20-meter error in determination of boundaries causes a ± 40 percent error in determination of the area.
