| چکیده | ||
| پوشش گیاهی برخصوصیات خاک تاثیر بسزایی دارد و می‌تواند از طریق مکانیسم‌های مختلف باعث تغییر خصوصیات فیزیکی و شیمیایی خاک شود. به‌علاوه گیاهان تثبیت کننده نیتروژن با افزودن نیتروژن به خاک موجب حاصلخیزی آن شده و نیاز خود و گیاهان همراهشان به این عنصر را تامین می‌کنند. مطالعه حاضر با هدف بررسی اثر حضور Astragalus cyclophyllon بر برخی از خصوصیات شیمیایی خاک انجام شد. به این منظور نمونه برداری از خاک تحت تسلط تاج پوشش Astragalus cyclophyllon وگونه Bromus tomentellus به‌عنوان گیاه شاهد (گیاه غیر لگوم) و همچنین خاک شاهد (جایی که هیچ گیاهی در آن حضور نداشته) در دو عمق 30-0 و 60-30 سانتی‌متر در قالب طرح کاملاً تصادفی انجام شد. سپس خصوصیات شیمیایی خاک از جمله درصد آهک، EC، pH، درصدکربن آلی، نیتروژن معدنی و نیتروژن کل خاک اندازه‌گیری شد. همچنین آنالیز گیاه محک به‌منظور بررسی اثر گیاه مورد مطالعه بر درصد نیتروژن، پروتئین و تولید گیاهان زیر اشکوب در مقیاس آزمایشگاهی مورد مطالعه قرار گرفت. نتایج نشان داد که مقادیر نیتروژن معدنی، درصد نیتروژن کل و درصد کربن آلی خاک در عمق 30-0 سانتی مترتفاوت معنی‌داری با دیگر تیمارها دارد (05/0P<). همین وضعیت در ارتباط با تولید، درصد نیتروژن و پروتئین گیاه محک کشت شده درخاک نمونه‌برداری شده از از عمق 30-0 سانتی‌متری تحت تاج پوشش Astragalus cyclophyllon نیز دیده شد. بعلاوه مقدار این فاکتورها رابطه معکوس با عمق دارد. مقادیر EC و pH درخاک تحت تاج پوشش Astragalus cyclophyllon کمتر از خاک بدون پوشش گیاهی است. | ||

| The aim of this study was to investigate the effects of environmental factors on distribution of Prangos uloptera in rangelands of Ardabil province. The habitats of Prangos were identified and the habitats, in which the study species was present, were selected. Sampling was also carried out in the vicinity of each habitat where the study species was not present. Three transects of 100-m length were established, on which canopy cover percentage and density of species were measured within 10 plots of 4m2. Soil samples were taken from the beginning, middle and end of each transect. In sampling places, altitude, slope, aspect, and soil characteristics were measured. Independent t test and cluster analysis were applied to comparison and classification of presence and non-presence areas and determination function was applied to determine the importance of factors affecting the presence of this species. The results of t test showed that there were significant differences between all variables except for temperature and precipitation. According to the results of cluster analysis, the studied species had more distribution in places with high altitude and steep slopes, high organic matter, and high nitrogen and sand. The results clearly showed that climatic parameters including precipitation and temperature as awell as altitude and sand percentage in the first grade and then aspect and soil characteristics including nitrogen and phosphorus in the second grade were the most important factors affecting the distribution of study species. According to the results, better decisions could be taken to use this species for range management, improvement and reclamation. | ||
