Field-protective afforestation in Kherson region: state and prospects
Journal Title: Лісівництво і агролісомеліорація - Year 2015, Vol 127, Issue
Abstract
The paper examines negative natural and anthropogenic impacts on modern agricultural landscapes of Kherson region. Substantial violations of ecological indicators of modern agricultural landscapes are noted to be caused by intensive use of natural resources, especially of soil. The negative impacts’ influence on agricultural landscapes of the Northern Black Sea region, leading to a significant decrease of humus content in soils and loss of their fertility potential, is investigated. At the model economies of the south and arid steppe subzones, the modern field-protective forest cover percent was established, which does not meet the modern scientifically grounded standards. At the initial stage of research, for the effective protection of soils and field crops, a differentiated adaptive-landscape principle for calculation of the required number of linear protective plantations was used for the first time for the region. The principle takes into account the predominant type of soil for each of the districts of the region. Project quantity of linear shelterbelts can provide favorable microclimatic conditions for agriculture. However, not only objective field-protective role of the linear plantations is important, but also environment protection and social functions in sparsely wooded southern regions. The estimated amounts of field-protective afforestation can significantly affect the ratio of total forest area of the region, which can reflect the level of resilience to the negative impacts.
