ترجمة الملخص

This research deals with the study of vegetation and soil cover in Jabal al-Hoss, as start this research studied natural properties in Jabal al-Hoss and then Classed vegetation by determining the units and classification of plant species in the all selected units , then studied plant and plant density in the selected units , and identified the factors that forms the soils in Jabal al-Hoss and studied soil sections for each units, then identified the physical and chemical properties and classified the soils of Jabal al-Hoss depending on the US classification then it analyzed plant diversity depending on several measures ,but the most important measure that is depended on is the and according to the biological types and determine the affiliation of the large geographical areas then plant diversity values according to Shannon's guide, also studied the relationship between plant diversity and natural factors that affects it, and then classified plant species according to their uses, and concluded the relationship between the mastery of special plant species on special soils and identified the uses of the lands in research shows that in the study area different rocky reveal configurations, the oldest of them belongs to the third geological time, which reveals over a wide area evaluate km2 or 99.5% of the total area of Jabal al-Hoss, and varies between (320-640) m with an average height of (380 -480) m, and controlled by mild half dry lower floor and mild dry downer in the western slope,as for the eastern slope that is being controlled by the dry fresh upper floor, although the form of the network that has many branching and it shape is away from the circular shape had limited the pose flooding in the region especially in the western slope that leads to further reduce drift and problems of both thesoil and vegetation, then Jabal Al-Hoss is divided to 54 units depending on the method of stacked sampling, the has been chosen 20 units (13 units representing the west slope and 7 units representing the east slope).It has been inventoried plant species per unit depending on the method of growing spaces where they were stripped of 152 plant species that is belonged to 114 genus and 36 family. After that putting a map of plant diversity depending on the species prevailing, the plant coverage, its percentage was ranged between (2-3), and it averaged the plant density in the Jabal al-Hoss 7.18 plant species per square meter.And it studied the most important factors that and it analyze and studying the physical and chemical properties of soils, it has been classified according to the following:1. vertisols: plant species is herb and 6 plant species are trees and 5 plant species are small trees and one type only sub-shrub, and through geographic affiliations of plant species we found that 33 plant species belongs to the Iranian region and 19 plant species belongs to the Mediterranean region and 6 plant species are common and 4 plant species are plants that belongs to the European Siberian region, and one belongs to the Arabian desert region and the rest are dual and triple affiliations, and by evaluating Shannon guide to the observed rise plant diversity in the basalt rock mother units, after that it studied plant diversity in the Jabal al-Hoss on several levels of approach (amount of plant diversity in the western slope of 134 plant species belongs to 108 genus and 36 family, and the slope of the eastern 91 plant species belongs to 77 genus and 31 a family) and its relationship to natural factors. It was concluded through this relationship that the directing factor and reflection on the climatic and soils characteristics has the biggest role properties of vegetation followed by the rock mother factor who has a role on the soils forming over it, and when the classification of plant species according of their uses it had been found 95 plant species have medicinal uses, without forgetting the importance of the plant species and especially that a number of them is threatened with extinction.Through land for the Jabal al-Hoss, we found that 761 km2 dessert (pastures) and 278 km 2 rocky land and 74 km 2 irrigated crops and 20 km 2 irrigated treed and 19 km2 industrial forests and 7 km 2 mixed crops, but it was noted that 54.14 percent of the mountain area is medium degradation and 28, 11% is strong degradation and 17.75% is very strong degradation, it was noted that the eastern slope is more deterioration than the western slope because it occur in a relatively dry climate and lack of basalt elevations resulting in an increase of the population and therefore increasing degradation
