In the thesis was mentioned about the further development of theory and methodology landscape science exploration, enriched the methodological basis and the content of regional agrolandscapes investigations was worked up. It was found the historical, natural and anthropogenic factors of influence on the agricultural landscapes of the Middle Pobuzhzhya, were highlighted the structure land of the territory. There was highlighted and investigated 61 landscape area – country between rivers, terraced, slope, erosion, floodplain and some types of the anthropogenic-man-caused forms, there were designed the maps of XIX и XX ct. landscapes of the Middle Pobuzhzhya. There was characterized the agricultural landscapes of the research's territory. The original final map of the agrolandscapes key areas – Desna basin was developed. It was suggested the improvement of the structure of agricultural landscapes of Middle Pobuzhzhya and defined the orientation of transformation and the possible weather condition and operation of modern landscape area of research. During field studies agrolandscapes Middle Pobuzhe foundthat compared to the landscape map for 1869 composition and value of agricultural landscapes have changed. An increase plowed slopes and, consequently, reduced area of grasslands, woodlands, wetlands others. In general, human pressure on agricultural landscapes grew while growth in urban and industrial areas. Physical-geographical characteristics and long-term development of anthropogenic study area resulted in the basic features of modern land use patterns: the dominance of arable land in the structure agricultural land; the main focus areas of arable land within the slope owners mezhyrichnyh plains in the upper and central parts of the basin; dominance in pastures slope and floodplain areas of the pool. In the future we can predict that in the present conditions of land use tended to increase arable land will continue. It was revealed that one of the reasons for the deterioration of the fertility of the soils of the Middle Pobuzhzhyais the non-compliance with the traditional crop rotation. The current market conditions force agrarians to grow, first of all, energy-bearing crops, which often leads to neglect of crop rotations.This is especially true for sunflower, corn, soybean and, most recently, rape, which belong to so-called «heavy crops», which deplete the soil. In recent decades, increasing the area under sunflower over 7 times and rape nearly 10 times. The increase in soybean acreage due to increased demand for oilseeds and processed products in the international market. In the years in the Middle Pobuzhzhya is probable reduction in corn acreage while increasing the area under oil. Field research and analysis of long-term plans for agricultural development Middle Pobuzhe give rise to the conclusion that in the near future field landscape area should be reduced to environmentally sound standards ratio of natural land and arable land (28–32 %). This reduction will help optimize the use of agricultural land in the region. In the next 15–20 years the main measures for rational use of natural and within the Middle Bug region obviously would need to focus on optimizing the use of agricultural landscapes. Future agricultural landscapes have become more diverse. It must be supplemented with meadows and pastures, forests and ponds. In highly developed countries meadows and pastures occupy on average 22 % of their territory. The real tool to optimize the use of land, the new ordering the territory and regulation of land relations, as the experience of developed foreign countries, can only land use (primarily modern real land registry), which should ensure the transition to a new land system with new forms of management, ownership and land use.
