| در سالهای اخیر استخراج از معادن به‌طور چشمگیری افزایش‌یافته و سبب تخریب منابع طبیعی و محیط‌زیست شده است. این تحقیق به‌منظور بررسی تأثیر فعالیتهای معدنکاری بر تنوع، غنا، یکنواختی و ساختار پوشش گیاهی در مراتع اطراف معدن مس دره زرشک واقع در استان یزد انجام شد. جهت انجام تحقیق سه سایت نمونهبرداری بافاصله (200-0)، (500-200) و (1000-500) متر از معدن انتخاب و سپس در هر سایت 3 ترانسکت 200 متری به فاصله 50 متر از هم به‌صورت عمود برجهت شیب مستقر و در هر ترانسکت 15 پلات 2 مترمربعی به فاصله 10 متر از هم قرار گرفت و در هر پلات، درصد تاج پوشش گونه‌های موجود و تراکم هرگونه ثبت شد. نتایج تجزیه واریانس برای شاخصهای مختلف تنوع، غنا و یکنواختی گونهای نشان داد که تمامی شاخصها در سه محدوده موردبررسی تفاوت معنیداری داشته است (05/0. p <). به‌طوری‌که شاخصهای غنا و تنوع بافاصله از معدن افزایش مییابد و در عوض شاخص یکنواختی پوشش گیاهی در نزدیک معدن بیشتر است. همچنین افزایش فاصله از معدن سبب افزایش معنیدار درصد تاج پوشش تیره‌های Asteraceae، Fabaceae،Poaceae، Chenopodiaceae و Lamiaceae در پوشش گیاهی گردید (05/0 p <). علاوه بر این برخی ساختار پوشش گیاهی نظیر ژئوفیت، کاموفیت، همی کریپتوفیت، بوته‌ای‌ها، علف گندمیان و چندساله‌ها به‌طور معنیداری در نزدیکی معدن کاهش یافتند. به‌طورکلی نتایج حاکی از آن بود که انجام عملیات معدنکاری تا حد زیادی بر ساختار پوشش گیاهی منطقه تأثیر گذاشته است و سبب کاهش تنوع گیاهی شده است. لذا لازم است در بررسی خسارت‌های وارده به مرتع موردتوجه قرار گیرد. | ||

| Mining has increased dramatically in recent years and, destroys natural resources and the environment. This study was carried out to investigate the effect of mining activities on diversity, richness, evenness and structure of vegetation cover in rangelands around copper mine of Dareh Zereshk located in Yazd province. Three sampling sites (0-200), (200-500) and (500-1000) meters far from the mine were selected for the study. Then, on each site, 3 transects of 200 m with 50 m apart, Were affected Perpendicular to the slope direction. In each plot, canopy cover percentage and density of plant species of existing species was recorded. The results of variance analysis for different indicators of species diversity, richness and evenness showed that all indicators had significant differences in the three study areas (p <0.05). So that the richness and diversity indices increased with distance from the mine and instead the evenness index was higher near the mine. Also, increasing the distance from the mine significantly increased the percentage of canopy cover of Asteraceae, Fabaceae, Poaceae, Chenopodiaceae and Lamiaceae(p <0.05). In addition, some structure of vegetation cover such as geophyte, chamophyte, hemicryptophyte, shrubs, grasses and perennials were significantly reduced near the mine. In general, the results showed that mining operations had a significant effect on the structure of vegetation in the area and reduced plant diversity. Therefore, it is necessary to pay attention to the pasture damage in the rangeland. | ||
