З’ясовано сучасне антропогенне навантаження на територію басейну на підставі комплексу показників, які відображають структуру землекористування території та ступінь її урбанізації. Досліджено екологічний стан басейну річки Сівка за показниками екологічної стійкості ландшафту. Здійснено екологічну оцінку якості поверхневих вод на підставі даних інтерактивної карти забруднення річок України, виконаної Державним агенством водних ресурсів України.

The subject of the study is the ecological and geographical problems of a small river basin (case study of the Syvka River, tributary of the Dniester River) and the educational and methodological aspects of studying the local river in school geography. The aim of the paper is to: a) study the dynamics of the river network of the Syvka River basin during the period 1925-2008; b) explore modern anthropogenic pressure on the territory of the basin and water quality; c) develop methodology of project studies of the river basin in school geography. The density of the river network was calculated based on the historical and modern maps and the cartography of the density of the river network of the Syvka basin was compiled as in 1925-1927 and in 2008. During the investigated period, the density of the Syvka river basin tends to increase (the maximum increase +1.5 km/km2) in the lower part of the river, which is associated with the laying of canals in the middle of the twentieth century. At the same time, the upper part of the river basin, which falls on the Zalysk and, partly, on the Voynilovskaya hill, is characterized by a decrease in the density of the river network, which is connected to the disappearance of small streams. The maximum diminution of the density of the grid (–1,3 km/km2) is characteristic for the basin area near the town Dolyna due to the densification of the settlement of the floodplain of the river. The anthropogenic load on the Sivka basin, was calculated on the basis of land use patterns, and does not pose a threat to the functioning of the river, however, 46% of the basin territories are occupied with ecologically unstable landscapes, whereas the remaining territories are relatively stable. The ecological assessment of the surface water quality allows to categorize the water of the Syvka River to the 3rd grade out of 5, and according to these categories, it is “average” water, and for the degree of purity – “moderately polluted”. The topic raised in the research allows to realize the competence approach in studying geography, in particular, such content lines in the modern school geography as “Ecological safety and sustainable development”, “Health and safety”. The research can be used as an algorithm for a school local environmental project, the main purpose of which is the students’ independent awareness of the natural sciences problems that have a vital meaning for them, the assessment of the state of the environment of the basin of the local river, and the provision of measures for its optimization.ukDynamics of the river systemregional research projectSyvka River basinдинаміка гідромережірічковий басейн Сивкикраєзнавчо-дослідницький проектСтаття
