Исследование и картографирование техногенной нагрузки на современные ландшафты Белорусского Полесья

Abstract

Рассмотрена территориальная дифференциация техногенной нагрузки в пределах Белорусского Полесья. На основании литературных данных и материалов собственных исследований составлена серия карт техногенной нагрузки на современные ландшафты Белорусского Полесья. Установлено увеличение нагрузки с северо-востока на юго-запад Полесья. Для лесохозяйственных и природоохранных типов ландшафтов характерны заметно меньшие значения величины техногенной нагрузки, без существенной пространственной дифференциации. = RESEARCH AND MAPPING OF TECHNOGENIC LOADING ON THE MODERN LANDSCAPES OF BELARUSIAN POLESYE

Abstract Purpose. The article considers the territorial differentiation of technogenic loading on the territory of Belarusian Polesye. Methodology. The mapping technique of technogenic loading on the natural and agricultural landscapes is developed, which takes into account the introduction of mineral and organic fertilizers, pesticides, ameliorants and receipts of dust of different origins, in addition with substances that fall together with precipitation per year. Mapping was performed using ESRI ArcView and ESRI ArcGIS. Finding. Based on the literature data and own research materials compiled a series of maps of technogenic loading on the landscape of the Belarusian Polesye. Established that technogenic loading to agricultural landscapes varies from 6.3 to 17.6 tons per hectare, is thus observed increasing it from the north-east to south-west Polesye. Strict dependencies between the genera of landscapes and the value of the technogenic loading is not established. For the types of forestry and nature conservation landscapes are significantly smaller values technogenic loading (not greater than about 1 ton per hectare), without a significant spatial differentiation. Results. A number of territories of the Belarusian Polesye are requires environmental measures to reduce the impact of technogenesis on landscapes. For the West Belarusian Polessye should be defined optimal rates of technogenic loading on the agricultural landscapes according to the local agricultural specialization and soil cover structure.
