STUDY CONCERNING FOREST ECOLOGIC RECONSTRUCTIUON ON DEGRADED LAND IN RANGE OCOLUL SILVIC “VALEA CIBINULUI”, SALISTE, ROMANIA

The study examines the stationary conditions, determine solutions to improve degraded land, assessing the cost of ecological restoration work needed in the area of improving degraded lands at Rapa - Copăcel, estimated benefits of the project and its viability. Objectives of the paper: need to introduce in the circuit of productive forest lands within the improvement of the area "La Rapa - Copăcel" danger zone where activation of the phenomena of degradation (erosion , landslides ) predominate. Out of 102.33 ha as area for improvement, the effective area of 101.6 ha is forested, representing a difference of 0.73 ha, 1.2 m wide strip that is to be the place for hedges. Viability of the project results from the ratio calculated benefit/cost = 2.3 which justifies the need and opportunity for investment. Opportunity project results in immediate and potential beneficial effects of the a forestation namely stabilization by stopping land erosion and landslides with positive influences on human settlements, infrastructure and communication lines, reducing the intensity of land degradation processes and the gradual improvement their production capacity as the direct effect of forest cultures, the role of forests in improving the main factors of environmental water, air, climate, reducing extreme values of climatic factors (temperature, evapotranspiration, wind speed, humidity) and air purification by the ozoning phyithoncide releasing the destructive effect of microbes; regulating rainfall, ensuring constant and permanent water flow, reducing the effects of drought and floods, improving stationary conditions for the maintenance and development of herbaceous vegetation and forest. It specifies the role and sanogene functions of the forest ? ambient of the forest, an constructive and necessary factor for the ecosystems and human health, and its other roles: aesthetic role "attribute of all forests" - contemplating a sylvan landscape with positive effects on the psyche (lights, shadows, colors, contrasts, echo), thus improving the appearance of the landscape area surrounding Loamnes; diversifying and increasing social functions, conservation of biodiversity, creating a favorable climate for wildlife, creating database, nectarous economic effects are related to obtaining wood in a wood shortage area.
