To preserve and increase the biological and landscape diversity, it is necessary to have comprehensive information about the conditions and dynamics of changes in the study object, a specific local ecosystem. Nature reserves are created to restore habitats, to protect endangered species of flora and fauna, vulnerable or complex species. Particular attention should be paid to the study of wetlands, a stabilizer of the hydrological regime of ecosystems, and a shaping element of the regional climate. It is proposed to involve remote sensing and Earth observation methods to address studying issues of the conditions of the wetlands. Space images are used to monitor, inventory, and map natural resources, observe seasonal and perennial changes in the natural environment, and assess the impact of anthropogenic activities on the natural environment. The calculation of spectral index was used to analyze the dynamics conditions of the plant communities and moisture supply on the Beloozersk section territory in Rivne Nature Reserve. It is proposed to use information-analytical technologies and data processing to study dynamic changes in the conditions of wetlands. ArcGis tools are used to collect, collect, process, formalize and present data on influencing factors and the shape of the ecological ecosystem. Such studies can be the basis for creating a system for monitoring the condition of vegetation and its moisture supply in the study areas. [ABSTRACT FROM AUTHOR]

The core of renewable natural resources of any nation is its natural reserve fund. The issue of natural ecosystems preserving is becoming more and more actual at the present stage in terms of increasing human influence on the environment. The article presents methodical approaches to improving the system of background environmental monitoring, increasing of its objectivity and data submission visual aspects on the basis of GIS - technologies - taking into account the status, characteristics and specifics of protected areas. It is proposed to use information - analytical technologies data processing to conduct research on the dynamics of changes in the state of natural territories. ArcGis tools are used for collection, accumulation, processing, formalization and presentation of data regarding impact factors and environmental ecosystem state. The above tools provide for interpretation of analysis results in graph form on electronic maps and implementation of mathematical methods for assessment of intensity of anthropogenic impact and modeling of its environmental consequences. Synthesized interactive cartographic materials are created with the help of modern information technology of geodata analysis, have high visibility and can be updated with further use by environmental institutions. The practical application of the results can be used in the development of environmental network, the main purpose of which is to ensure the preservation of bio-and landscape diversity, the implementation of background environmental monitoring, stabilization of environmental balance, increasing of landscapes productivity, improvement of the environment and provision of nature reserve fund territories environmental safety. In addition to image visualization, developed environmental and cartographic models are the basis for studied territory environmental state assessment and compiling a set of digital thematic maps in GIS environment. In order to carry out an assessment of the components of the protected nature reserve, to ensure environmental safety and to prevent hazardous impact, it is possible to analyze the state of the natural reserve area in detail and systematically using GIS technologies.
