Morphometric Analysis of Territories OccupiedBy Agricultural Land, Located in the Suburban Zone of the Volgograd Agglomeration
The article presents the results of the main geomorphological characteristics (slopes and exposures of slopes) study relative to agricultural land located in the green areas zone of recreational use in the Sovetsky district, according to the functional zoning scheme of the Volgograd city Master Plan. Territorial planning documents may contain data that does not fully reflect the state of the objects that are located on certain sites. Therefore, the problem of including agricultural land in the green areas zone for recreational purposes is urgent. At the same time, in order to plan certain measures to rationalize the land use, it is necessary to analyze the research objects terrain. The author uses data from remote sensing of the Earth, such as the digital terrain model (DTM) SRTM 1 Arcsecond, as well as high-resolution satellite images of the study area. With the help of geoinformation processing, data on the distribution of agricultural land types by exposure points andslope gradations were obtained. The territory was evaluated according to the main geomorphological characteristics. The predominance of a warm group of expositions and weakly-sloping slopes was established, which has a favorable effect on the growing processes of the main agricultural crops. These data can be used in the development of not only a system of arable land rational use in the study area, but also in the planning of their reclamation. A discrepancy was found between the functional zoning content and the actual situation in the place. The obtained data can be used in the proposal to amend the scheme of the Volgograd city territory functional zoning, in particular, to replace the category of functional zone in the zone of green areas for special purposes (agricultural). Also, presumably, when developing green areas on the studying territory, instead of agricultural ones, it is necessary to take into account the steepness of the slope and the exposure for the green spaces planning.
