چکیده

به منظور بررسی تاثیر عملیات اصلاحی مرتع بر عملکرد پوشش گیاهی، تحقیقی در مراتع سیلوانا در استان آذربایجان غربی انجام گرفت. در این مطالعه چهار عملیات اصلاح مکانیکی شامل پیتینگ، سدهای گابیونی، کنتور فارو و سد سنگی ملاتی انتخاب شدند. در کنار سایت های عملیات اصلاحی سایتی به عنوان سایت شاهد(بدون انجام عملیات)، انتخاب گردید. سپس در مناطق معرف هر سایت نمونه برداری از پوشش گیاهی به روش تصادفی- سیستماتیک انجام شد. پارامترهای پوشش گیاهی شامل میزان تولید، درصد پوشش، میزان لاشبرگ و تراکم اندازه‌گیری شدند. داده های حاصل از اندازه گیری با استفاده از آزمون آنالیز واریانس یک طرفه مورد تجریه و تحلیل قرار گرفتند. سپس میانگین پارامترها با استفاده از آزمون دانکن با یکدیگر مقایسه شدند. تحلیلهای آماری در محیط نرم­افزار SPSS انجام شدند. نتایج آنالیز واریانس یک طرفه نشان داد که عملیات اصلاح مکانیکی مختلف از نظر تاثیر بر عملکرد پارامترهای گیاهی با یکدیگر تفاوت معنی داری دارند. با توجه به نتایج مقایسه میانگین ها، نیز مشخص گردید که دو عملیات مکانیکی سد سنگی ملاتی و کنتور فارو بیشترین تاثیر را در افزایش و بهبود عملکرد پارامترهای گیاهی نسبت به سایر تیمارها در منطقه سیلوانا داشتند.

چکیده [English]

This research was aimed to investigate the effects of range improvement treatments on vegetation performance. The study was conducted in Silvana rangelands, West Azerbaijan province. In this study, four improvement treatments including contour furrow, pitting, gabion and mortar stone dams were selected. A control site (with no improvement treatment) was also selected. Vegetation sampling was done in a random-systematic manner in key areas of each site. Vegetation parameters including production, canopy cover percentage, litter and density were measured Data were analyzed by one-way ANOVA. Then, the mean values of parameters were compared with each other using the Duncan test. Statistical analysis was done in SPSS software. The results of one-way variance analysis indicated that the study mechanical improvement treatments had significant difference in terms of performance of plant parameters. According to the results, among the study treatments, contour furrow and mortar stone dam had the most positive impact on increasing and improving the performance of plant parameters, compared to other treatments in Silvana region.
