Seventy years' experience of creation of the state protective forest strips in a steppe zone of Russia In a steppe zone of the European territory of Russia artificially created 8 state protective forest strips (SPFS) are located. Research objective: on the basis of analytical materials to carry out the assessment of a condition of SPFS of a steppe zone of the European part of Russia, to reveal their recreational potential. Materials and methods of a research: general information, creation history, ways and technologies of creation of SPFS, lesovodstvenny actions in them were studied and analyzed according to references and share materials. Information on existence and condition of SPFS in regions of a steppe zone of the European part of Russia was established according to the state forest register. For certain regions the recreational appeal of SPFS paid off.  In article the history of creation of these strips, since adoption of "The Stalin plan of transformation of the nature" from 20 оctober 1948 g is considered.  On this project in 15 years (1949-1965) it was planned to create 117.9 thousand hectares of SPFS, but actually works were finished in 1972. 4 water separate and 4 prirechnykh state protective forest strips were created.  Now the total area of SPFS in a steppe zone of the Russian Federation is 85.7 thousand hectares. At the same time more than 13% of their area are presented by not forest lands, and covered with forest vegetation are about 80%.  From tree species as a part of SPFS the Quércus róbur prevails, the second place is taken by an Fráxinus excélsior  and F. lanceolate, the third Ulmus pumila. It is established that more than a half of the spaces are occupied by middle-aged plantings, 16.6% – coming, 8.9% – ripe and perestoyny. The state protective forest strips have the recreational potential which increases in process of increase in a share of SPFS as a part of forest fund of the territory; and in process of decrease in the general woodiness of the territory.  The SPFS recreational value increases at increase in their availability (first of all transport) in comparison with other territory of forest fund.

The influence of the groundwater level regime on the biological productivity of wood species in the forest bands of the Stone Steppe The influence of the groundwater level regime on the biological productivity of wood species in the forest bands of the Stone Steppe CheverdinYurii I.1, Akhtyamov Alexander G.2,Sautkina Marina Yu.3, 1V.V. Dokuchaev Scientific Research Institute of Agriculture of the Central-Chernozem zone, Voronezh, Russia 2Stony Steppe experimental forestry, Voronezh, Russia 3All-Russian Research Institute of Forest Genetics, Breeding and Biotechnology, Voronezh, Russia Abstract: Studies conducted in Dokuchaevsk agroforestry complex. The soil cover is characterized by a significant diversity and the nature of moisture. In this regard, the aim of the research was to assess the formation of forest stand depending on soil moisture. The materials of the carried out taxations of forest strips during the last century were used. For all test sites, a detailed analysis of the species composition, number of trees and growth parameters of the middle tree of the first tier is given. The average volume of wood supply stem wood per 1 ha was calculated on a single table "Forest of the subsidiary books." The processes of growth and development of tree crops in old-age plantations are shown. The features of the forest biological processes occurring in the protective forest plantations created by the foresters of the special expedition of prof. The influence of the regime of groundwater level on the growth parameters of the tree stand components. The dependence of growth and development of tree species on the distance from the main underground flow has been revealed on the basis of the materials of the forest strip inventory. On the formation of stands in different conditions, soil moisture has more influence than the proportion of oak in planting schemes of mixing. Analysis of the composition of the first tier stands shows that over the past 70 years on the Central segment of the formula composition of the stand 6D, 2Яо, 1Яп, 1V+Ko. Forest inventory in 1936 (age 41) it was 6D,2Яп,1Яо,1V. Formula of woody composition has changed slightly.  

Transformathion of hydrological regime of agrolandscapes with protective forestations The estimation of  hydrological regime of virgin territories and those exposed to anthropogenous impact in various degree is given . The analysis of protective forestations influence on melted water surface runoff formation,on water balance members and erosion-hydrological processes has been implemented .The law of melted water runoff limiting factors permitting new approach to the estimation of erosion-hydrological process is exposed. The method of high precision prognosis of surface runoff has been developed on its basis .Analysis and estimation of the efficiency of anti-erosion methods have been fulfilled ,the most effective ones have been educed, new high-efficiency practices have been developed and anti-erosion melioration strategy is proposed .

The ecological situation of Petrozavodsk municipal district urban forests The characteristic of the current sanitary and forest pathology conditions of 45 urban forest sections of Petrozavodsk urban district of the Republic of Karelia has been done. Data processing was conducted using GIS technologies, principal component analysis and by averaging the point estimates using the median. There were allocated 5 group sections of urban forests: minimum (17 % of total urban forest area), weak (18 %), medium (31 %), strong (4 %) and maximum (30 %) disturbed. It is proposed to use the obtained data for rational planning of urban development.

The Wood and Ohotpromyslovoe Use of the Baikal Natural Territory: the Aspect Connection of Logging to Hunting Tradeo Leontiev D. F. The interpretation of natural systems as objects of the corresponding of economy impact has executed. The condition of impact on the natural complexes has reflected. The forecast of their changes has given. The impact of logging on volumes of booty of hunting products has shown.
