Problems and monitoring the spread of the ecologically dangerous plant Heracleum Sosnowskyi in urbanized areas and methods to combat it

The article contains information on the breeding of Heracleum Sosnowskyi for cultivation as a forage crop in the post-Soviet period. Information about the ecological danger of the spread of this plant is given. Its juice contains furocoumarins, which, when exposed to human skin under the influence of ultraviolet rays, cause serious burns on the surface of the body. The article presents materials testifying to the increased adaptability of the Heracleum Sosnowskyi to the habitat conditions and its high fertility. The spread of Heracleum Sosnowskyi in urban areas (in parks, playgrounds on undeveloped lands, etc.), as well as in rural settlements of the country, due to the environmental hazard for people, leads to the removal of land from economic circulation. The authors of the article have established the regions and reasons for the spread of Heracleum Sosnowskyi in the European part of Russia. The substantiation of the monitoring of lands for the registration of habitats of this dangerous for the ecosystem is given. The article provides information on assessing the extent of the spread of Heracleum Sosnowskyi in the territory using remote sensing using unmanned aerial vehicles. The article discusses measures to combat Heracleum Sosnowskyi

Technology for creating electronic soil maps based on archival materials for land management engineering

The article considers the structural and logical scheme of the methodology for creating electronic soil maps for land management engineering based on analog archival cartographic materials. The proposed scheme includes seven blocks: 1) building frames for 1:50,000 scale topographic map sheets in the geoinformation environment “Map 2011”; 2) scanning analog topographic maps with a scale of 1:50000; 3) binding a bitmap images of topographic maps to the sheet frames and cropping the frame image; 4) converting data from the GIS “Map 2011” to the GIS “MapInfo”; 5) scanning of archive analogue 1:10,000 scale soil maps and their binding to electronic 1:50000 topographic map in GIS “MapInfo”; 6) defining precision of referencing the raster 1:10,000 scale soil map to topographic 1:50,000 scale map; 7) bitmap image vectorization of a 1:10000 scale soil map in the GIS “MapInfo”. The content of methodology’s each block is disclosed. The developed methodology can be used for cartographic support of land management engineering and territorial planning

The water exchange and water quality improvement measures on the example of the Gulf of Cheboksary

This paper is dedicated to the Gulf of Cheboksary. The gulf has an important recreational and decorative function. It has been an integral part of the urban landscape for several decades. There is an eutrophication process, accompanied by the development of blue-green algae and the appearance of an odour in early spring, despite the water quality improvement measures. Measures that will improve the water exchange in the Gulf are proposed in this paper. Problems with the sanitary condition of the water body can occur without taking these measures. Therefore, the theme of this research is quite urgent

Assessment of Natural Resource Potential of a Territory for Planning of Investment Development and Construction in Suburban Areas

The paper describes the types of assessment and assessment process of the natural environment. A review of judgments about the ecological and geo-ecological assessment of the environment by known academics, environmentalists, physical geographers, geobotanists is made here. In this paper the method of the environmental assessment of natural resource potential within the North-West region of Russia is proposed. Authors divide this method into blocks, which are described in the paper. A produced method for evaluating territory used to calculate the cadastral value of land

Geoecological evaluation of the territory in the GIS environment in the preparation of information for land management design

This study focuses on improving the technology for the preparation of geospatial information for land management design. The following hypothesis was the basis of the study: if the technology of geoecological assessment of the territory in the GIS environment is developed in the preparation of information for land management design, then its quality will increase, and as a result, the effectiveness of managerial decisions in the field of environmentally friendly land use will increase as well. The geoecological assessment of the territory is understood as the mathematical-cartographic, spatial, multi-parameter analysis of the auspiciousness of its agro-resource and geoecological conditions for sustainable production of plant agricultural products without disrupting the functions of life support (environmental and resource production). The developed technology can be used to solve the following problems: a) improving the land management system; b) improving control of land management; c) the formation of a database on the suitability of the territory for agricultural development, taking into account its sustainability; d) the territorial distribution of agricultural loads based on the geoecological situation. The advantage of the technology developed by the authors lies in the fact that a really working mechanism of geoecological assessment of the territory in the GIS environment is created when preparing information for land management design, which will allow to improve the quality of the developed design solutions and as a result will ensure the environmental safety of the functioning of natural and agricultural systems and the careful use of land resources

The formation of land use at the waste storage facility of the pulp and paper industry

The article provides materials on the natural restoration of land cover in the territory occupied by the waste storage facility of the pulp and paper industry. The article contains information on the level of soil fertility formed on this territory as a result of decomposition of organic waste over 25 years. The composition of the phytocenosis is presented. The article provides materials on the ecological state of the studied object, and also considers the technological operations of reclamation of an authorized landfill in the areas of forestry and recreational land use, taking into account the ecosystem formed at the storage facility

Mathematical Modeling of Hydrophysical Properties of Soils in Engineering and Reclamation Surveys

All structures are built of, or through, or supported by earth materials including soil. Thus soil surveys in civil-engineering field are an important step in the construction. A lot of things depend on their results, especially the cost of construction, durability. The hydraulic conductivity needs one of the most laborious, and expensive surveys, thereby it is necessary to reduce these disadvantages. Were considered different methods (a laboratory, field and a mathematical model), and conclusions were drawn about economic feasibility of using the least laborious method. This method can be used under the various constructions, when engineering or reclamation surveys take place
