英文摘要	A vast part of the drylands worldwide is characterized by patchy vegetation coverage expressed by shrubby patches and biocrusts inter-patch space (BIS) between them. Recent studies indicated that the BIS microorganism species richness increases similarly to shrubs. They became denser during the shrubland maturation, leading to possible ecohydrological interrelations between the shrubs and the BIS. Nevertheless, these interrelations are not clearly understood and all are suited to mature and well-established shrublands. The study hypothesizes that a hydrological interrelation, which relates to the main limiting factor in such arid (or semiarid) areas, exists between the shrub, its patch, and the BIS and are changed from the shrub establishment until well established patchy form. The objective of this study is to determine empirically the factors that influence the ecohydrological interrelation from unsettled shrub BIS, shrub establishment, to mature shrub patch. The study was carried out on typical arid shrubland in Sde- Zin, the Central Negev Highlands, in 2019. The study analyzed the chemical, physical and hydrological characteristics of eight common shrub species, their patches, and their BIS. The finding indicates that mature biocrust in the interpatch is characterized by high water mobilization of 70%, which is a little less than the one achieved on a rocky coverage (80%). The study finding enables to create a holistic mechanism for the shrubs and BIS developments and the formed hydrological interrelations. In the initial stage before the shrub settlement, the BIS is characterized by low water mobilization ability. In the second and third stages, the settled shrub gradually forms a patch, while the change of the BIS is small. In the last one, changes in BIS led to enhanced water mobilization to the shrub patch. From then, rainfall and adequate land management may lead to patch enlargement and increased biomass, resulting in shrubland rehabilitation.
