Identification of fallow land for the intended use to basin organization of natural resource management

© SGEM2017 All Right Reserved. Satellite images analysis conducted using modern ERS methods allows to allocate lands which can be referred to the deposits based on a group of diagnostic indicators and using a number of techniques. Change of vegetation cover type associated with change of fallow lands use features is manifested in their spectral response, including the vegetation index values (NDVI). In the course of experimental studies the peculiarities of seasonal dynamics of vegetation index for the initial few years after the transfer of the cultivated area in the state of deposit were calculated and analyzed. The key feature of the index dynamics for deposits older than three years is a relatively stable course after reaching the maximum values and the fluctuation around values above 0.6. The article deals with the change of farmland area and issues of its intended use control. When addressing economic neglect of agricultural lands it is first of all necessary to identify the environmental reasons related to soil degradation and contamination, and, as a result, taking of large areas of arable land out of use. To transfer unproductive land to less intensive forms of land or other land categories the criteria for their selection shall be developed. Agroecological evaluation results should become one of the main criteria for selection of lands unsuitable for agricultural use, if their transfer is necessary. A structural model of natural resource management and ecoregion sustainable development based on the concept of basin natural resource management and analysis of the negative impact on the natural environment elements has been offered. It has served as a basis for development of measures related to implementation of the rehabilitational land use in the study area. Possible measures for degraded soils conservation and recovery have been offered

Integration strategies of academic research and environmental education

The paper deals with the prospects of using GIS-technologies and remote sensing ones as the main directions of implementing the innovation project in the sphere of environmental education. The paper suggests new models and technologies in the system of teaching that rely on the obtained experience of implementation of environmental education tasks and integration of modern technologies into ityesБелгородский государственный университе

Indicators of agricultural soil genesis under varying conditions of land use, Steppe Crimea

This study investigates the effects of agricultural exploitation of soils of the north-western Crimea, the active and large-scale cultivation of which began with the Greek colonization of the area. In order to compare soils using a wide spectrum of physical and chemical properties, the studied objects (virgin land, post-antique idle land, continually plowed land, modern-day plowed land, idle land of the modern era) have been grouped into a chronosequenceyesБелгородский государственный университе

Climatic factor in long-term development of forest ecosystems

The purpose of work was to develop regional tree-ring chronologies for modern and ancient periods, to establish the connection of radial growth (including indices related to early and late wood) with climatic indicators and reconstruction of ancient climate based on dendrochronological data using new methods of time series processing. Using a complex of statistical methods climatic parameters reconstructions and chrono-organizations of half-century changes in forest site in ancient times were performe

Investigation of winter cereal crops development based on their spectral reflectance properties

The article presents the results of analysis of winter cereals spectral reflectance characteristics obtained using remote sensing data. The samples of sowings typical of the Belgorod Region and the Central Black Earth Region were used for the research. The experimental data were received from 158 sowing areas. It has been established that the difference in sowing time has more influence on the difference in winter cereals phenophases occurrence than on the over-wintering conditions. Snow melting in the fields on certain dates of the winter period can be clearly identified in NDVI seasonal trajectories values. The influence of sowings growth after the winter period on vegetation index values is shown using ground data. NDVI variation coefficient value and test of hypothesis for normal distribution in certain time slices may serve as criteria defining the uniformity degree of biophysical parameters of plants growing in various sowing areas. During the periods when the phases of development are leveled, sharp decreases in random variation and standard deviation are observed. It has been established that the maximal homogeneity of vegetation cover and green phytomass of the sowings is observed from the second half of May until mid-June. The minimal values of NDVI variation coefficient (5-6%) calculated for each analyzed date at an interval of 16 days are observed in mid-June

Using GIS technology for identification of agricultural land with an increased risk of erosion

The article discusses the results of spatial analysis of agricultural land in geographic information systems for automated identification of arable land with high risk of soil water erosion. For the Belgorod Region, which has a high soil and climatic potential and is one of the leading agrarian regions of Russia, a spatial model for potential clean fallow-based rainfall erosion has been constructe

Biogeochemical features of fallow lands in the steppe zone

Fallow lands in ancient agricultural areas of Northwestern Crimea which had experienced repeated phases of agricultural activity at different time periods (the Late Bronze Age, antiquity, and the last 150−200 years) have been studied. The most informative and evolutionarily significant biogeochemical indicators of relict agricultural loads and duration of fallow periods are specifie

A new approach to dating the fallow lands in old-cultivated areas of the steppe zone

We have determined the landing rate of limestone into soil on uneven-aged surfaces (mound and de-posits) in the ancient agricultural steppe region of the Northern Black Sea Region (chora of Kerkinitis) with well represented carbonate soils. To make reasonable choices of objects of study we used an integrated approach, which includes historical and cartographic analysis, GIS-technology remote sensing and field GPS-referencing. It is shown that the most objective factor that can be used for dating long-fallow lands is the mean volume of subsurface rocks based on a large sample method (30 or more measurements

Basin and eco-regional approach to optimize the use of water and land resources

The paper presents the principles of justification of the boundaries and composition of ecoregions as hydrologically separate, integral natural and economic structures, within which a quantitative and qualitative assessment of the results of the geoplanning of integrated components of the territories of nature, population and economy on the basin principle can be most effectively carried outyesБелгородский государственный университе

Postantique soils as a source of land use information: a case study of an ancient greek agricultural area on the Northern Black Sea coast

This paper explores ancient land-use practices in order to reconstruct the original parameters of the land division system, as well as agricultural techniques employed. For postantique agricultural landscapes, an integrated geoarchaeological approach that includes GIS and remote sensing methodologies, in-field study of microrelief and soil registrograms, pedochronological dating technique, and physicochemical, geochemical, and biomorphic soil analyses has been developed and teste
