Definition Of

A chaotic oscillatory correlation network for scene segmentation is presented. It is a two-dimensional array with locally coupled chaotic elements. It offers a mechanism to escape from the synchrony–desynchrony dilemma. As a result, this model has unbounded capacity of segmentation. Chaotic dynamics and chaotic synchronization in the model are analyzed. Desynchronization property is guaranteed by the definition of chaos. Computer simulations confirm the theoretical prediction.

Ecological Potential

The concept of ecological potential is realized by development of biogeographical and bioecological maps. Experience of preparation of a set of integrated bioecological maps of Russia of scale 1 : 8 000 000, displaying biot as a whole is presented. It includes maps – Zones and altitudinal zonality types of vegetation of Russia and adjacent territories, Ecoregions of Russia, Bioms of Russia. Maps are developed on the basis of allocation regional (ecological division) and typological (bioms diversity) divisions biote a cover. These divisions can serve basic units at geoinformation researches of modern ecological potential, a binding of the information according to a biodiversity and to a condition biote at national and regional levels. On them it is possible to make inventory of a biodiversity, the major parameter of ecological potential of landscapes, to choose characteristic and unique objects for monitoring and conservations, to planning the actions connected with sustainability progress lands and conservations ecosystems and other.They are directed on revealing of ecological potential of territorial units (zones ecoregions bioregions) through the ecological characteristic biote or on revealing of differentiation biote (zonobioms group of regional bioms regional bioms) through the characteristic of its ecology-typological variety.
