Symposium on Remote Sensing for Resources Development and Environmental Management / Enschede / August 1986 521 Remote sensing methods of monitoring the anthropogenic activities in the forest V.I.Sukhikh All-Union ’Lesprojekt’ Association, Moscow, USSR ABSTRACT* Main directions of the Earth*s remote sensing data use for the monitoring of the USSR forest fund changes caused by anthropogenic activities are considered* Indices charac terizing the accuracy of determining the parameters of the monitored units by aerial space photography and observations materials are listed* Large-scale works on developing and remaking of the whole regions and natural-territorial complexes are characteristic of the second half of the 20-th century. Such works are carried out in the USSR in the European-Ural zone, Western and Eastern Siberia, Far East, Middle Asia and Kazakhstan* National econo mic activities in these regions influence the forest fund and tree-shrub vegetation* The range of the anthropogenic activities having an influence on the forest dynamics and sta te is quite wide* It includes forest cutting and reforestation, drainage, securing forest growing, tree care, rock exploitation, civil and industrial construction, forest fires, agricultural development of the forest fund lands, industrial effluents, recreation,etc* The increasing versatile significance of the forest on the one hand and the growing anthropogenic influence on it on the other hand put before forestry management organs a primary and complicated task on the ratio nal use and reproduction of all types of fo rest resources and their useful properties* But in order to solve it objective timely information about the state of the tree-shr ub vegetation and about all the important changes in the forest fund is needed first of all. As the forest fund area is large and the access to it is difficult remote sensing means are widely used in the USSR in order to reveal, assess and take into account the changes which occur in it* New methods and technologies of forest study and control of their dynamics and state are being worked out, and the existing methods and technolo gies are being improved by means of the mo dem remote sensing means complex use, and development of interpretation and mapping methods• Information is obtained with space and avi ation observation means and ground spot in vestigations* To carry out the photography and monitoring from space artificial Earth satellite (AES) of the 'Meteor' and 'Kosmos' series, and long-term orbital 'Saljut' sta tions (LTOS) ensuring the getting of multi- zonal scanner and photographical information with the resolution of 20m to 100-30Qm and lkra are used, and instrumental-visual obser vations are carried out* Aviation means make it possible to obtain photographic informa tion with the ground resolution of several centimetres to tens of metres* In choosing means and methods of informa tion obtaining the optimization task is be ing solved: minimal labour (especially in the forest) and money expenditures, and maxi mal necessary information by the volume and quality* Space and aviation remote sensing materials must ensure the getting of the main information volume, and ground observa tions have to be carried out only in those cases when the remote sensing information is not complete* The greatest changes in the forest fund result from clear cutting which is carried out with the aim of logging and also clea ring of the forest fund territory in the process of economic development of the ter ritories* Forest cutting involves the neces sity of observing a number of rules regula ting its organization, conducting and refo restation on the cut areas* Hence the major task is the control of the forest exploita tion order which has to ensure the estimate of the harvest cutting rules observance, evenness of using in the region the forest fund of different qualitative state (in or der not to allow the immediate cutting of the best by quality forests); cutover area state assessment; specification of the re maining forest raw materials resources; de termination of the reforestation tendency and the course of young growth formation on the cutover areas* At present in order to solve all these questions methods the tech nical basis of which is the aerial photogra phy materials have been developed and tested* The method of control over the harvest cut ting rules observance is intended for the joint use of space photographs obtained from 'Kosmos' artificial Earth satellites and 'Saljut' long-term orbital stations* The com parison of space photos of different photo graphy years with forest management materi als, plans of cuttings and cuts, topographic maps make it possible to estimate the size of each separate cutover (its length, width, area), cutting techniques and their corres pondence to the forest protective < character category and site class; direction of cut overs, terms of their contiguity, number of first cuttings in the quarter, their loca tion relative to the relief forms, actual cutting terms; the degree of the young-gro wth safety, safety of the middle-age and ripening stands, temporal forest seedling plots* Cutting volumes are measured by space pho tos by measuring or automatized methods* The comparison of data obtained by photographs with the ground investigations results shows that the systematic errors of the cutting
