The article examines the issues soil erosion a risk traditionally rapidly growing with agriculture in tropical and semi-arid regions, which is particularly important for its long-term effects on soil productivity, removing topsoil, than soil formation processes can replace it due to natural, animal and human activities, in the example, excessive grazing, cultivation, deforestation and more mechanical farming and sustainable agriculture. Studied the spatial characteristics of grass and arable land formations, their positive impact on anti-erosion installations research. Developed methodological framework mapping of soils from the threat of erosion.

In recent years, the development of agriculture comes increasing, due to the increasing population in various countries. Average annual growth for the last irrigated land of the TWENTIETH centuries was over 3 million hectares. Irrigated area on the globe exceeded 220 million hectares. The total area of the Republic is 8641.5 thousand ha. Of these, 3610thousand hectares, or 43.23% of the soil of the Republic Fund places in one or another degree were subjected to erosion. Here historically formed complexes with environmental problems [1-3]. In the most precarious status of land resources, which almost everywhere in varying degrees subjected to degradation, the intensity of which depending on terrain parameters morphometric climatic and soil-plant conditions, as well as economic activity degree often reach catastrophic proportions. This contributes to the destabilization of the ecological situation in the Republic. [3,4] In Azerbaijan, in addition there is the problem of salinization of soil degradation (Figure 1).

The Republic is described as a land-hungry country, where per capita accounted for 0.2 hectares of arable land. It should also be noted that in Azerbaijan there are also lowland conditions slope crossed conditions, which requires a special approach to technologies and technical means of irrigation. Being a mountainous country, Azerbaijan is characterized by complicated natural conditions cool physiographic areas-greater and Lesser Caucasus, Kura-Arax River lowland and the Talyish mountains, strongly distinguished from each other on geological structure, climate, soil and vegetative cover, terrain slope, which range from 1 to 40 and more Highly developed in the Republic, existing in the nature of almost all types of erosion. Soil erosion is a serious problem throughout the world. Soil erosion is a serious environmental, economic and social challenges; it’s not only lead to land degradation and loss of productivity of soils, but also threatens the stability and health of the Society of universal and sustainable rural development in particular in mountain regions of the Republic (as Shamakhi, Axsu, Ismailia, Gabala, etc.) soil erosion is the removal of topsoil than soil formation processes can replace it due to natural, animal and human activities such as overgrazing, cultivation, deforestation and more mechanical farming [3- 5].

Spatial Characteristics of Herbaceous Formations and Cropland in the Objects of Study

A review of the literature devoted to soil erosion and its prevention in Azerbaijan, confirms the positive impact of antierosion herbaceous formations. A study conducted by us, under the leadership of Prof. BH. Aliyev in Terter PARADISE (2008-2010) and Shamakha OEB Institute erosion and irrigation NANA (2011- 2013) on the effect of vegetation on pastures in the runoff and sediment yield showed significant influence of runoff and sediment yield. Establishment of control factors of vegetation and water on the slopes of the motor way, Shamakhi OEB was the reduction of vegetation water cause erosion to intercept rainfall, increase water infiltration to soil fertility, interception of runoff on the soil level surface and stabilizing soils under coarse ground. [1.3] Analysis of properties of arable land in Axsu district height and slope of the terrain showed that up to 60.0% of their area is located at an altitude of more than 500 m from the sea level. On the basis of landuse maps, it was found that the main plant, grown on arable land in the region, vineyards, orchards, wheat, legumes and forage crops.

It belongs to the Group of plants that have good ohranami properties in relation to soil and besides, rather it tolerates water shortages during the growing season. Cultivation of wheat imports, together with appropriate machinery, should to a large extent, protect arable land in the region from water erosion. The selected for the analysis region of Azerbaijan, located on the Southwestern slopes of the Great Caucasus are three types of herbaceous formations: pastures, Green land -steppe. Their location depends on various factors surrounding the region Wednesday. Placing herbaceous formations, in terms of height and slope, was analyzed within the boundaries of Axsu district. In this area they occupy 24% of the total area, including: grassland-52%, green lands, almost 28% and 20% of the steppe. The most extensive high-altitude pastures have intervals, placed at an altitude of 1400 m above sea level. In high-altitude 600-70 m intervals and 700-800 m number of largest pastures, respectively 19 and 20% of the total area of the territory. Almost 50% of pastures is located on slopes with a gradient 10- 18% (6-100 ), and in the lower grades of slopes-0-6% (up to 30 ) and 6-10% (3-60 ) - 20%.

Pretty much of 7.5% is on the slopes with inclines of up to 27% (150) Green lands are located at an altitude of 1000 m above sea level. Largest area-60%, are at a height from 200 to 50 m above sea level (by 20% in areas of 200-300, 30-400 and 400 and 500 m). More than half of these grassy% 54-formations is located on slopes with a gradient 10-18% (6-100 ) and 22% with a slope of less than 6-10% (3-60 ). Steppe vegetation, often used as winter pastures, is observed in the lower altitudinal zones. In Axsu district, they are below 300 m above sea level. Almost 70% of the footprint is located below 100 meters above sea level and 98% on the gentle territories or lands with a slight slope from 0 to 6% (0-30 ). Areas covered with herbaceous vegetation formations are also dry river valleys [7]. They occupy less than one per cent of the total area to be analyzed. There are up to a height of 400 m above sea level and 95% on flat or gently sloping areas. [1.3.7] The actual problem is erosion caused by caused:

a. mismatch plant species in a mixture of perennial herbal and leguminous plants,

b. too many cattle per hectare of pasture,

c. grazing animals on too steep slopes, especially with southern exposure

d. too early onset of grazing.

Reduction of the intensity of agricultural production and, especially, the intensity of grazing animals, as well as adaptation to the conditions of grazing techniques habitats above the grassy formations will strengthen their anti-erosion value.

Methodological Framework Mapping of Soils from the Threat of Erosion

Map of the threat from surface water erosion was established on the basis of: slope, soil maps and maps of land use map slopes received as a derivative of the layer digital elevation model (SRTM 90 WGS 1984), and then the retrofit to the erosion model in their class bias. Soil map was vectorization and editorial processing. The primary material was scanned map with an average magnitude of rectified lined topographic maps (1:100 000) and classified in 5 groups of sustainability the soil leachate may run off. Land use map was also based on scanned maps vectorization Land Cover Classificationtion System-FAO [1:50 000 scale 3.5].Based on the results of the research, the following erosion and patent risk maps of the Axsu and eastern parts of the Ismayilla region created based on GIS technology, respectively, were compiled. see (Figure 2 & Figure 3) Maps a threat from erosion (potential and actual) was established on the basis of Polish methodology, given the natural conditions Azerbaijan and list of legends to soil the soil map of Azerbaijan. Map of the actual threat from erosion was established way of reduction of degrees of potential danger from erosion, with accounts of the main land use categories (forests, permanent grassland, degree and arable land). For forest land and permanent grassland, which possess a very considerable degree of functions anti erosion erosion threat reduction was at 3 units. For the steppes on the reduction unit 2 was adopted, while agricultural areas only 1 unit (Table 1). [2,3] the large change in average annual rainfall amounts Axsu area was a partition into two geographical parts: dolinnuju (South), where the average annual rainfall is within 300- 800 mm, as well as mountain-precipitation is higher 800 mm.

In the example of Ismailia district, because of its typical hilly topography, to map the potential erosion were accepted criteria relating to mountain territories. Data on mean annual precipitation were obtained from Atlas of Azerbaijan Republic for the year 2007. [1, 3, 7] Analysis of the threat from erosion for Agsu district showed a strong effect of land use on reduction of erosion. This is the greatest mountain refers to the territories in which the significant reduction of all degrees of erosion threat, sparked the growth of the territory, not exposed erosion, more than 81% (Table 3). In the area of lowlands erosion reduction is primarily concerned with 2, 3, 4, and 5 degrees. Area, subject to erosion threat 2 degrees was reduced from 5516 HA to 412 hectares. Territory subject to erosion threat 3 and 4 degrees, only 96 ha, and 5 degrees was reduction to 0. A higher percentage of territories with 1 degree of threat from erosion in the mountainous part of the region is associated with the presence of a small amount of forests and large crops of wheat (Table 2). [1,2,6]. Residents of the area placed in regions with a significant incline of the ground, which increases the percentage of the highest degree of potential danger from erosion. Almost 48% of the analyzed of Ismailia district is threatened by erosion, 3.4 and 5 degrees (Table 3).

A very big impact on the reduction of the intensity of surface water erosion raises some concerns about the sustainability of the advanced technologies used in the work methodology for the study area. In this regard, it would seem appropriate for field verification data, taking into account the impact of land use on washing away topsoil. Another issue not related to the influence of surface water erosion, is the development of the territory of landslides. They create a large loss for Azerbaijan’s infrastructure and may be subject to further study, including the modelling [8].
