Оценка фрагментации экологической сети Луганской области

Abstract

Today in Ukraine there is no single approach to the formation of the ecological network. Ecological network in the region are built on the same principles, but using a different methodology. Most scientists do not consider issues of fragmentation of territories, which are among the main criteria for selecting areas for inclusion in the ecological framework. Functional ecological network will only work if local populations of flora and fauna inhabit the main fragments. In reality, the opposite occurs. It creates areas that have state protection. Functionally, they are not viable and propped up by human factors. The article describes the evaluation of the fragmentation of the ecological network of Luhansk region as an example Antratсit region Lugansk region. A database for analysis and formed of digital printing sources. The sources of information included in the database was compiled Program of Ecological Network of Ukraine for 2000 – 2015, data of regional and international projects for the creation of the ecological network of the region, the inventory of natural reserve fund of Lugansk region, atlas of natural reserve fund of Lugansk region, the European Atlas of Soil and publications dissemination of plants and animals in the region, Luhansk atlas, cartographic and satellite data. Because of simulation obtained information about the fragmented areas in the district. Natural Area – 872.12 km2, accounting for 52,47% of the total land area. The amount of natural fragments in the Grand – 2257 items to 1662.19 km2. Analysis of fragments permitted confirmation of the main areas for regional ecological network. The data obtained verified in the field and are described in terms of functionality. The study found that fragmentation is very high. This estimate makes it possible to confirm the functional elements of the ecological network, and create a forecast for its expansion.
