The Research of some Elements from Climate Regime with the Influence of the Forests from River Somes upon Vegetation Condition

摘要

According to the definition, the forests are the landscape’s product and essentially depend on climatic factor. The geographical distribution of forest species and formations is determined, with some exceptions, by this complex factor, mainly by the thermal and fluid component of it. Corroborating the climatic conditions with the sensitivity of forest species and the adaptability of phytophagous agents, given the lack of some strong and concentrate actions to combat, it can be explain the long presence of some pathogens and attacks in some areas and stands.
