Blinkova O. 3. Ecosystem-landscape features of alteration of econet on the Crimea's Southern coast.

3. This dissertation presents the theoretical conclusions of the main principles and methods concerning an estimation of conditions and natural reserves fund of the Crimea's Southern coast, which are exposed to anthropogenous, anthropogenous-natural and natural negative factors. Spatial distributions of main threats to biodiversity and influence of natural negative factors to structural units biodiversity for whole ecosystem are determined on landscape. It was described causally-investigatory relations, improved the diagnostic criteria of the forest's ecosystem in natural reserves fund by the types and intensification of ecological negative influence: recreational load, forest's fires, soil real estate development, erosion, storms. There is a decrease of hydrological role of vegetation and development of planar soil erosion, speed up of degradation in the anthropogenic damaged forest's ecosystems especially eastern part of southern Crimean mountains macro hillside and the lower part of watershed. The degraded ecosystem has depressed or even absence of forest nature recreation, which lead to brake biodiversity structure, break the ecosystem structural connection, decrease its firmness. It has been shown that the main danger for PZF objects and econet elements is excessive recreational load which lead to soil erosion and forest's fires from 2 to 20 km in radius around such cities as Yalta, Sevastopol, Alushta. Storms and wind brakes of tree stand occur on the reservoir sites with highest pressure of the wind. Spatial distribution and the diagnostic feature list of ecosystem transformation was established, which will promote regulation of negative influence on the natural environment.
