Technique of Disturbance of the Vegetation of South of Pribaikalye Using Space Images and Landscape Map

E. A. Istomina
In monitoring and assessing the state of the vegetation and the landscape in general often not taken into consideration the information on their root (potential, undisturbed) state. Designed and illustrated a method of rapid assessment of vegetation cover disturbance using satellite images and landscape maps, where landscape map display potential state of the vegetation. There are the following geosystems states: areas without vegetation or with sparse vegetation (goltsy, fresh fairs, pastures and hayfields), herbal and grass-shrub communities, deciduous woods, light coniferous forests, dark coniferous forests. For each type (group facies) of landscape map of the south of Eastern Siberia (1: 1 500 000) possible stage of regenerative successions and root state were identified, as a result a map of the indigenous (potential, recovered) landscapes was made. ISODATA classification of satellite image Landsat MrSID with the release of the same five classes was made and a map of the current state of landscapes was created. Calculation of the difference in these two geoimages allows to determine the degree of disturbance of vegetation and to make a map of disturbance. From the map it can be concluded that as in 2000 the prevailing part of the territory is relatively undisturbed. Areas with varying degrees of disturbance are confined mostly to the coast of the lake Baikal and the flat basins sites.
