Risk-based model of nature management in the conditions of the Dolinsky reserve of the Sakhalin region

Abstract

On the territory of the Russian Federation there are more than 13 thousand specially protected natural areas (hereinafter referred to as SPNAs). In general, within the boundaries of these protected areas, the economic use of lands is prohibited or significantly limited, which is mainly due to their special status associated with the need to preserve and reproduce endangered species of flora and fauna and their habitats. Permitted types of activities and nature management in the Dolinsky State Natural Complex Reserve of Regional Importance (hereinafter referred to as the Dolinsky Reserve) are associated with the need to implement territorial infrastructure projects for the oil and gas complex of the Sakhalin Region, namely, the construction and maintenance of linear structures of the transport infrastructure. At the same time, the peculiarities of the geographical location of the Sakhalin Region, the peculiarities of the geological, geomorphological structure, climatic and other features of the region, for the safe implementation of permitted types of nature management in this territory, require taking into account existing and potential risk-forming factors that can be realized in the form of hazards and threats to natural and man-made nature. This necessitates risk-based modeling based on the identification of risk-generated parameters on the territory of protected areas and the use of the entire available information array to calculate the possible risks of hazardous and emergency situations in the study area. In the course of the study, based on the materials of satellite images Landsat-8, Sentinel-2A, SRTM data, as well as the analysis of statistical data on seismic activity, fire hazard, flood conditions, and technogenic load of the study area, an assessment was made of the state of the Dolinsky reserve territory (Sakhalin Island). As a result, sufficient information content of the source materials was revealed, a risk-based risk assessment model was developed, the results of the data processing and calculation methodology were demonstrated, and a risk map of environmental management in the conditionsof the Dolinsky reserve was compiled.
