this study was carried out to investigate the effective environmental factors in the distribution of vegetation in zirkouh rangelands of qaen. after delimitation of the study area, sampling of soil and vegetation were performed using randomized- systematic method. vegetation cover was recorded by using braun-blanquet combined abundance-cover scale in each sample. within each sample, one profile...
The physical and chemical characteristics of soil water sources affect desert plants’ growth, which is essential for the ecological protection in arid areas. typical patch patterns Haloxylon ammodendron oasis-desert ecotone southern margin Manas River Basin consists bare patches (BP) vegetation (VP). H. were studied using stable isotope technology, properties monitored analyzed. results showed ...
Shallow groundwater is an important water source for Haloxylon ammodendron (H. ammodendron). The accurate estimation of evapotranspiration (ETg) from great significance the cycle and maintenance ecological stability. Using a combination balance method level fluctuation (WTF), components (precipitation, soil moisture, depth, Bowen ratio meteorological data) in desert–oasis transition zone were c...

Subsidies are an effective instrument to encourage farmers engage in afforestation which provides many ecosystem services. A scientific and reasonable subsidy level should reflect the demands of various stakeholders so that scheme can be accepted by both government. This study aimed establish a framework for designing attract voluntary participation way seeks raise farmers’ government’s returns...
In arid desert areas, Haloxylon ammodendron plays an important role in maintaining the ecological balance of oases. However, there are few studies on physiological characteristics under environmental gradient. Here, we studied changes morphological and photosynthetic their correlations four habitats Ebinur Lake wetland. Our results show that high-water high-salt habitats, photosynthesis is affe...
Nitrogen deposition can change the soil in N and C cycling processes. However, a general understanding of how changes mineralization has not yet been reached. Soil organic beneath dominant shrubs Haloxylon ammodendron between response to two levels addition (2.5 gN m−2 5 per year) were investigated 1st, 4th, 9th year temperate desert northern China. promoted (RmN), nitrification rate (RNN) incr...
