It is an example of a natural structure that is spontaneously restored after long-term economic use (hayfields, pastures, long-term plowing, summer cottege settlements, drainage and irrigation channels, silt sites, etc.) under conditions of cessation of intensive anthropogenic impact. The article deals with the history of the formation and development of the Zakharkovskaya floodplain in prehistoric times (late Holocene), in the early historical period (beginning-middle of the second millennium AD), and in the late historical period-XIX-XXI centuries. The regulation of water flow, which has occurred in recent decades, is accompanied by a relative stabilization of the Moscow riverbed, turning it into a canal, reducing the intensity of channel deformations, leveling the bottom relief with its general deepening. As in other floodplain plots, the territory of floodplain leaves the flood zone; depressions are filled in, lakes are degraded, and man-made terrain is formed. At the same time, the current restrictions on access to the territory of the Zakharkovskaya floodplain for 10-15 years have created conditions for the restoration of natural structures, in particular, forest and shrub tracts, and increased the landscape and ecological attractiveness of floodplain lands.","PeriodicalId":131329,"journal":{"name":"Bulletin of Udmurt University.

Of these, Solanum emulans is a new species for the flora of Russia. It is brought to the city of Izhevsk with North American grain. In 1993, three of its locations were discovered: at the Izhevsk railway station and in the wastelands in the courtyards of the Izhevsk bakery plant and the Izhevsk bread-receiving enterprise no. 2. Solanum scabrum is occasionally cultivated by amateur gardeners as an exotic plant. In a wild state, it has been known since 2000. To date, eleven of its locations are known in the cities of Izhevsk, Votkinsk, Mozhga, Sarapul, as well as in Zavyalovsky, Uvinsky, Yakshur-Bodinsky and Yarsky districts. Most of its finds are associated with dumps and municipal waste dumping sites. In the conditions of the Udmurt Republic, Solanum emulans and Solanum scabrum are ephemerophytes. The features that distinguish Solanum emulans and Solanum scabrum from morphologically similar species such as Solanum americanum, Solanum nigrum., Solanum retroflexum are given.","PeriodicalId":131329,"journal":{"name":"Bulletin of Udmurt University.

On their basis, most of the hydrological calculations and structures are made, without which high-quality and rational water use is impossible. Unfortunately, in the Kaliningrad region, there are a number of difficulties with obtaining a complete set of recorded results of hydrological monitoring carried out over watercourses. The aim of the work was to collect hydrological information and calculate the main hydrological characteristics of the river flow of some watercourses in the Slavsky region. All the available data on hydrometric observations of the rivers of the considered territory were collected, on the basis of which hydrological series of average annual discharges were compiled. These rivers are: Zlaya, Osa, Matrosovka and Nemoninka. The missing data in the hydrological series of the average annual water discharge of the rivers under consideration were restored. The curves of the provision of average annual expenditures have been built according to the reconstructed data, and the average long-term expenditures, coefficients of variation and coefficients of asymmetry of the studied water bodies have been calculated. The entire methodology was based on the current set of rules for hydrological calculations. The results obtained can play an important role in further geoecological studies of watercourses in the Slavsk region, planning their use and in various project activities to develop water use.","PeriodicalId":131329,"journal":{"name":"Bulletin of Udmurt University.

Correlation communications of productivity grain with a temperature mode and water supply during the separate periods of growth of plants are considered. Are received regress models of various kinds for forecasting of productivity and the role of each climatic factor in these models is estimated. On this basis the basic natural factors of formation of a grain yield are revealed. On the basis of the analysis of time numbers of meteorological indicators on temperatures and deposits during the summer period the equations of a trend which on a long-term interval prove laws of growth of daily average temperature and monthly average deposits are received.

In the vicinity of Krasnoyarsk, there are 20 specially protected natural areas: national Park of Federal significance - 1, complex reserve of regional significance - 1, biological reserves of regional significance - 5, geological natural monuments of regional significance - 8, 2 hydrological - 2 and Botanical -3. The highest score of recreational potential was given to the Krasnoyarsk Pillars national Park - 11 points and the Karaulnaya Cave geological nature monument-12 points out of 15, as these protected areas include unique natural objects, differ in landscape diversity, have a developed tourist infrastructure and are located near the city of Krasnoyarsk. The territory of the national Park \"Krasnoyarsk Pillars\" of all specially protected natural areas is subject to the greatest environmental risk (1 point), has a significant recreational load with an overall high recreational potential. Nature monuments \"Mininsky Pillars\", \"Chernaya Sopka\", \"Badzheyskaya Cave\" and \"Bolshaya Oreshnaya Cave\" have the greatest natural attractiveness, transport accessibility, and low environmental risks in the overall high assessment of recreational potential (9-10 points).
