ЭКОЛОГИЧЕСКОЕ СОСТОЯНИЕ ЛИМНОСИСТЕМ СЕВЕРО-ЗАПАДА БАРАБИНСКОЙ НИЗМЕННОСТИ
ENVIRONMENTAL STATUS LIMNOSISTEMS NORTH-WEST BARABA LOWLAND

Summary/Abstract: For the diagnosis of the current state and development forecasts of possible changes in ecosystems are necessary observations to qualitatively assess their ecological status. Integral expression of the ecological state of limnosistems perform the chemical composition of water, knowledge of which is necessary to address the issue of intensive use of lake resources. Compo-sition of water is formed under the combined influence of internal and external processes (phys-ical, chemical and biological) defined landscape factors, reflecting zonal specific conditions of formation and intra-zonal variability. Interrelationship and interdependence of lake watershed, expressed in the composition and number of elements in the water chemistry, their distribution in time, the conditions of migration and transformation. On the example of one of the districts Baraba lowland considered the possibility of using landscape ecological and geosystem-limnological approach to assessing the state of small reservoirs. As an environmental condition parameters of different types of lakes are used macrocomponental characteristics and major hydro-chemical parameters (pH, total hardness, salinity), the gross value of the concentration of elements in the water of the lakes and their degree of geoenvironmental, especially water mi-gration. The role of the factors causing local differences. In the conclusions of the regional characteristics of the environmental situation in limnosistems.
