چکیده
Abstract Recently, pastoral ecosystem has been strongly studied by naturalists. However, phytoecological research must focus on species richness and enhance these ecosystems. The main objective of this is to prove that the Moroccan very rich in terms soil biodiversity plant formations. In such areas, some plants maintain physicochemical characteristics soil. field experiment was based Braun-Blanquet sampling method with 90 surveys. vegetation surveys carried out during spring 2014–2018 period showed there were 30 families, 23 orders, 99 (47 perennial 52 annual or biennial species). Of inventoried, 14 are rare (RR) (14% total flora), six (R), five suspected (R?), three extinct doubtful presence (??), two vulnerable (or seem be), decline, could become short term (V), one a taxon (RR?). Investigation life forms Raunkiaer various different forms. Among them, terophytes (47%) 2% phanerophytes had highest lowest species, respectively. This work led us discover ( Atractylis cancellata , Carduus pycnocephalus Scorzonera angustifolia Telephium sphaerospermum Teucrium luteum Androsace maxima ) types rangeland eastern Morocco. Chorology results high proportion Mediterranean biogeographic study area, percentage 35%. North African followed Mediterranean, 14%. Euro-Mediterranean constituted major flora arid regions played significant role rangelands 8%. Eurasian 6%, Asian forming 4% species. Eurasian, Paleo temperate, same (3%). remains represented low percentage, but contributed diversity phytogeographic potential

در این پایان نامه به بررسی روش های آشکارسازی در سیستم های mc-cdma می پردازیم. با توجه به ماهیت آشکارسازی در این سیستم ها، تکنیک های آشکارسازی را می توان به دو دسته ی اصلی تقسیم نمود: آشکارسازی سیگنال ارسالی یک کاربر مطلوب بدون در نظر گرفتن اطلاعاتی در مورد سایر کاربران تداخل کننده که از آن ها به عنوان آشکارساز های تک کاربره یاد می شود و همچنین آشکارسازی سیگنال ارسالی همه ی کاربران فعال موجود در...
Soil-Vegetation Relationships in Arid Rangelands (Case Study: Nodushan Rangelands of Yazd, Iran)
The objective of this research was to identify the vegetation-soil relationships in Nodushan arid rangelands of Yazd. 5 sites were selected for measuring the cover of plant species and soil attributes. Soil samples were taken in 0-10 and 10-80 cm layers. The species studied were Salsola tomentosa, Salsola arbuscula, Peganum harmala, Zygophylum eurypterum and Eurotia ceratoides. Canonical corres...

Biodiversity is one of the important concepts in ecology and vegetation management, and plays an important role in the health, production, and evaluation of ecosystems. Species diversity is a major part of biodiversity and one of the most important parameters of ecosystem changes. In this research, the data of the rangeland evaluation different climate zones of Isfahan province were used in fiv...
