Enclosure is commonly used in the restoration of degraded grasslands. However, effects enclosure on grassland plant and soil remain controversial, particularly deserts. To assess desert plants properties, using high throughput sequencing, differences between were systematically analyzed before after construction. The organic carbon, total nitrogen phosphorus contents three flora increased decre...

black saxaul (haloxylon aphyllum) is one of the best options for rehabilitating drought affected desert lands. the species is remarkably adapted to the central dry environment ofiran and a major source of raising pasture productivity of the areas. progenies of 25 randomly selected black saxaul trees from four populations of the species were studied in a randomized complete block design with thr...

The study of plant photosynthesis under different degrees drought stress can provide a deeper understanding the mechanism resistance. In Taklimakan Desert, saline groundwater is only local water source with regard to shelterbelt construction and determines growth photosynthetic changes. this study, daily dynamics gas exchange parameters their responses photon flux density at three irrigation le...

Compared to surface water, groundwater resources are the primary source of water supply in arid and semi-arid regions of Iran, hence the importance of the management of these resources .  In this regard, we assessed the effects of landuse changes on the qualitative and quantitative status of groundwater resources in Eshtehard region, Iran. Through processing and analyzing the satellite images, ...
