| پایداری خاکدانه و ساختمان خاک به عنوان شاخصهای کلیدی سلامت خاک مرتع بوده و از عوامل مؤثر در کنترل فرسایش خاک به شمار می‌روند. تحقیق حاضر به منظور بررسی اثر قرق بر وضعیت پایداری خاکدانهها و ساختمان خاک در چهار منطقه از مراتع استان گلستان شامل چهارباغ، اینچه‌برون، گمیشان و مراوه‌تپه انجام شد. نمونه‌برداری خاک از دو عمق 20-0 و 40-20 سانتیمتر با حفر پروفیل و به روش تصادفی-سیستماتیک و در امتداد هر ترانسکت در هر یک از سایتهای قرق و مجاور قرق مناطق چهارگانه انجام شد. پایداری خاکدانهها به روش الک تر در آزمایشگاه مورد اندازهگیری قرار گرفت. نتایج حاصل برای سایتهای قرق و مجاور قرق و نیز دو عمق مربوطه به ترتیب با استفاده از آزمون تی نمونه‌های مستقل و جفتی مورد تجزیه و تحلیل آماری قرار گرفت. نتایج نشان داد در اغلب سایتهای مورد مطالعه مقادیر پایداری در خاک سطحی نسبت به خاک عمقی بیشتر می‌باشد. نتایج بررسی اثر قرق مرتع بر تغییر مورفولوژیکی و وضعیت ساختمان خاک نشان از نقش مثبت قرق در توسعه ساختمان خاک در تمامی مناطق مورد بررسی داشته است ولی این نتایج در بررسی آماری پایداری خاکدانه تنها در منطقه اینچه‌برون و گمیشان از لحاظ آماری معنی‌دار شد. بالاترین مقدار پایداری خاکدانه در عمق اول سایت قرق گمیشان (52/4 میلیمتر) و کمترین میزان پایداری خاکدانه در عمق دوم سایت چرایی گمیشان (15/1 میلیمتر) مشاهده شد. بررسی نهایی نتایج نشان داد صرفنظر از نقش مثبت قرق در ارتقای وضعیت پایداری خاکدانه، عواملی همچون موقعیت جغرافیایی مرتع، اقلیم، نوع پوشش گیاهی و شرایط چرای دام به عنوان عوامل همراه قرق مؤثر بر پایداری خاکدانه و ساختمان خاک بایستی مورد توجه واقع شوند. | ||

| Soil aggregate stability and soil structure considered as the key indicators of range soil health and counted as effective factors in soil erosion control. The present study was carried out to investigate the effect of exclosure on the stability of aggregates and soil structure in four areas of Golestan province including Chaharbagh, Incheboron, Gomishan and Maravetapeh. Soil sampling was carried out from two depths of 0-20 and 20-40 cm by digging profile in random-systematic method along transects in each of exclosure and adjacent sites of quadruple areas. Aggregates stability was measured by the method of wet sieving in the laboratory. The results were analyzed statistically using independent and paired samples t-test for exclosure sites and adjacent exclosure sites as well as two corresponding depths, respectively. In the most of studied sites, the aggregate stability values were higher in the surface soil than the deep soil.The results indicated that the effect of rangeland exclosure on morphological changes and soil status indicating positive role in development of soil structure in all studied areas, however, these results were statistically significant only in the Incheboron and Gommishan area in view point of soil aggregate stability. The highest value of soil stability was in the first depth (4.52 mm) of Gomishan exclosure site and the lowest one was in the second depth (1.15 mm) in Gomishan grazing site. The final result showed that regardless of positive role of exclosure in promoting the stability of aggregate, factors such as geographic position of rangeland, climate, vegetation type and grazing conditions as the associated factors affecting the stability of aggregate and soil structure should be considered. | ||
