History of Science and Engineering Annotation << Back Structural-Functional Organization of Baikal Region Surface Ecosystems V.I. Voronin, Т.А. Mikhailova, L.V. Pomazkina, S.G. Kazanovsky, Yu.F. Palkin Complex investigation of structural-functional organization of Baikal Siberia surface ecosystems allowed to define present ecological situation and to make up the forecast of its development. There are developed principles of zone-setting of the territories by intensity of natural and anthropogenic factors impact; regional biological diversity on phytocenotic, species and population levels is evaluated. The results acquired allow to get a comprehensive idea of surface ecosystems resistance mechanisms. Key words: surface ecosystems; Baikal Siberia; resistance; biodiversity; photosynthesis; atmospheric pollution; enthomopathology; bioindication; agroecology.
