537 - the basis of direct and indirect data. During the field work, the selected test is carried out as well as calibration of characteristics, determined at the laboratory. The new technology reduces the extent of field estimation work approximately by 1.5 - 2 times, so the amount of estimation work carried out by a practising forester for a year increases by 1.5 times. Thus surveying and geodetic work are fully reduced and there appears 20-25 percent reduction of costs. The accuracy of estimation increases somewhat due to more detailed study of the total area of the forest compartment. While during the first years the new technology found its application in forest lands, rather simple in structure and had not been involved with forestry, at present it is used in rather complex forest lands. The annual amount of forest work which has been carried out on the basis of the technology, is over 5 millions hectares at present and the variant of the technology is elaborated upon because intensive forestry has a fructional structure, it is based on the rational combination of analysis and measuring in interpretation of false color multispectral aerial photographs at the scale 1:10000, with ground estimation and is in practise in forestry work in the Central regions of the European part of the USSR [1l]. The technology of forest inventory of mountain forests is elabo rated, and is based on the combination of the analysis and measuring inter pretation with ground estimation, based on the landscape method. This technology is now in practise in the North-West forest investigations in our country. Aerial methods are greatly applied to forest evaluation work in almost inaccessible regions of Central Asia. For the purpose of forest inventory of the forests, special methods are elaborated based on the rational combination of estimation measuring interpretation of aerial photographs with the scale 1:10000 - 1:15000 (black-and-white in deserts multispectral in highlands and lowlands) with a bit of field work and observations with the aid of airplanes and helicopters [5]. The existing technology of forest inventory, especially in desert vegetation has something in particular compared with forests of the moderate zone. One of the principal estimation indices is the diameter of crowns of chaparrals. Taking this index into consideration one might determine the number of chaparrals visible, then the areas of crown's projections are summarized and after that the calculation of the stock is carried out. There also exist correlative interconnections between the age and visible and measured indices of heighrt and diameter of crowns on the aerial photographs. The technique of airvisual investigation of rangelands of deserts is elaborated, and in combination with aerial estimation of forests it permits one to obtain a more exhaustive complex evaluation of the desert forest for the purpose of forestry. Lately the series of experimental work on the subject of application of large-scaled aerial (1:3000 - 1:5000) and (1:1000 - 1:2000)
