Construction the System of Maps to Support Environmental Researches of Petroleum Industry Facilities

There is an overview of actual environmental research practice and its map support in this article. The overview demonstrates peculiarities and disadvantages of ecological mappping on different stages of petroleum object life-cycle. The main disadvantage of the current practice that the setries of maps have different content and they are made in different scales. As a result we suggested a list of mandatory mas which show a minimum of necessary data about nature, technical objects, impacts.

The Results of Monitoring of Erosion Processes on Chernozems of the Volga Region

The article presents the results of monitoring of erosion processes on chernozems of the Volga region from 1973 to 2015. It is shown that the observed increase in winter temperatures can reduce the depth of soil freezing, increase the number of days with thaws and reduction of water reserves in the snow to the top of the snow melting. These processes improve the absorption of melt water conditions and lead to a decrease of spring runoff. In the last 30 years of flow value decreased by 3,8 times in the plowed fields, and compacted arable land – 5,7 times.
