ECOLOGICAL CONDITION OF THE SOILS ECOSYSTEMS OF KUZNETSKY BASIN [№ 12 ' 2017]
Kemerovo region is an industrial conglomerate which central part is occupied by the territory of Kuznetsky basin with developed coal mining industry creating great anthropogenic influence on environment components, especially on soil covering. In this paper the author considers ecological condition of soils ecosystems (natural and anthropogenic) related to objects of coal industry on the territory of Kuznetsky basin. The author gives comparative characteristics of content of mobile forms of heavy metals (HM) (Pb, Cd, Cu, Zn, Mn, Ni, Co, Cr) in soils of natural and anthropogenic landscapes. It is stated that the degree of heavy metals mobility in soils of natural ecosystems is determined by granulometric texture, oxidation-reduction potential, acid-base characteristics and organic matter content. As opposed to natural soils the main factors determining the level of heavy metals mobile forms content in soils of anthropogenic ecosystems are abiotic conditions of soil formation (mineralogical composition, correlation of coarse soil and fine soil in soil body) and the degree of organo-accumulative processes. The author evaluates inactivant capability of soils to pollutants. It is stated that soils of natural and anthropogenic ecosystems are characterized by different capabilities to heavy metals. Anthropogenic landscapes soils have lower indexes of inactivant capability. Among anthropogenic soils initial embriozems have minimal buffer capability. The received data is recommended to be used in monitoring studies to observe the level of anthropogenic impact on soils ecosystems of Kuznetsky basin and to prevent negative processes in soils usage.

FEATURES OF BEHAVIOR OF MOBILE FORMS OF HEAVY METALS IN THE SOILS OF THE KUZBASS [№ 10 ' 2015]
In the paper give a description the content and laws of spatial behavior of mobile forms of heavy metals (lead, cadmium, copper, zinc, manganese, nickel, cobalt, chromium) in the soils of the monitored grounds of Kuzbass. The coefficient of the radial differentiation of soils (R), which describes the distribution of mobile forms of heavy metals in the profile. It allows you to set the direction and influence of the type of soil formation, granulometric composition and soil properties on their behavior in a variety of soils investigated automorphic series. On the basis of the content of mobile forms of heavy metals and maximum allowable concentrations calculated the coefficient of the total pollution (Zc). By the dual analysis of the basic properties of the studied soils (content of physical clay, carbonate, organic matter, pH) assessed their buffering capacity. Comparative analysis of the contamination factor and the buffering capacity of the soils studied in the territory of Kuzbass in relation to heavy metals makes it possible to assess their ecological and geochemical condition. Negative factors of soil pollution and high levels of buffering capacity suggests a relatively favorable ecological situation in the territory of Kuzbass with respect to mobile forms of heavy metals.Results of research can be used in the development of soil-ecological monitoring of the territory of Kuzbass, to solve different problems of land use, protection and soils reclamation.
