On the basis of summarizing long-term studies are considered factor-spatial features of the content of organic matter in different types of small lakes the entire spectrum of natural areas in Western Siberia. To characterize the organic matter used indicators of water oxidation - permanganate (oxidation KMnO4) and dichromate (oxidation K2Cr2O7), as well as a set of conversion factors, which allows fully characterize the nature of the agents. For each landscape zone and the features of territorial differentiation, seasonal dynamics of organic matter. Geographical distribution of organic matter is characterized by increasing its content in the direction of freshwater lakes of the tundra ponds to the forest steppe zone, the highest possible concentration characteristic of hyperhaline steppe lakes. Territorial and seasonal dynamics determined by the ratio of allochthonous and autochthonous organic matter. In freshwater lakes tendency to increase the content can be traced to the beginning of the hydrological summer landscape in each region (dominated allochthonous organic matter supplied from the watershed), the maximum values observed in summer and autumn (increase of production of autochthonous organic matter), minimum – in winter. For seasonal dynamics characteristic organic matter salt lakes the largest concentrations in the winter-spring and autumn-winter period, and the lowest – in the summer. Specificity of the horizontal and vertical distribution of organic matter in all types of lakes closely connected with the peculiarities of overgrowing of lakes and hydrography. In conclusion, highlighted the value of background ratio of allochthonous and autochthonous organic matter in the zonal section and highlighted the role of anthropogenic factor.
