In this study, 19 sites representing different habitats in Hail region were regularly visited for two years, in each site 2-5 stands were selected for investigating floristic composition and vegetation types in the area. A total of 124 species representing 34 families were recorded. The family Asteraceae is represented by the highest number of species (21 species) followed by the Poaceae (17 sp...
ساختمان تشریحی هجده گونه از چهار جنس haloxylon , anabasis , hammada,seidlitziaاز تیره اسفناج مورد بررسی قرار گرفت. با وجود تشابهات مورفولوژیک و اشکالات موجود در تفکیک این تاکسونها بر حسب صفات مذکور،صفات آناتومی متمایز کننده ای در سطح جنس و گونه شناسایی شد. با استفاده از تاکسونومی عددی ،قرابت بین تاکسونها بررسی شده وتفکیک تاکسونها بر حسب صفات مورفولوژیک با نتایج این پژوهش تفاوتهای آشکاری داشته ...
Community dominant plants and their ecological niche research is the focus of community ecology research. To explore characteristics desert relationship between them soil factors in Qaidam Basin, to provide a basis for construction plant communities sustainable management natural resources Basin. Taking 13 Qinghai Province as objects, this paper analyzed species based on physical chemical prope...
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...
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...
