چکیده

چکیده
گیاهان ماندابی غالباً مهم‌ترین جزء اکوسیستم‌های ماندابی به شمار می‌آیند و به گیاهان آبزی، گیاهان پای‌درآب و گیاهان رطوبت‌پسندگروه‌بندی می‌شوند. در پژوهش حاضر، فلور مناطق ماندابی استان همدان شامل تالاب‌های طبیعی و مصنوعی، رودخانه‌ها، آبراهه‌های دائمی و فصلی و چمنزارهای مرطوب کوهستانی بررسی شد. نتایج بررسی حاضر نشان دادند فلور ماندابی استان شامل 45 تیره، 111 جنس و 163 گونه است. 13 تیره از گیاهان یادشده به تک‌لپه‌ای‌ها، 31 تیره به دولپه‌ای‌ها و
1 تیره به نهانزادان آوندی تعلق دارند. تیره‌های Poaceae با 19 جنس و 23 گونه، Asteraceae با 15 جنس و 20 گونه و Cyperaceae با 8 جنس و 19 گونه بزرگ‌ترین تیره‌های گیاهان ماندابی استان همدان محسوب می‌شوند. گیاهان ماندابی استان از نظر شکل زیستی، 8 گونۀ هیدروفیت، 51 گونۀ هلوفیت، 35 گونۀ ژئوفیت، 50 گونۀ همی‌کریپتوفیت،14 گونۀ تروفیت،
4 گونۀ فانروفیت و 1 گونۀ کامفیت را شامل می‌شوند. 29 گونه از عناصر رویشی گیاهان ماندابی استان همدان به ناحیۀ رویشی اروپا - سیبری، 38 گونه به ناحیۀ رویشی ایرانی - تورانی، 1 گونه به ناحیۀ رویشی مدیترانه‌ای، ۲۴ گونه به نواحی رویشی اروپا -سیبری/ ایرانی - تورانی، ۲ گونه به نواحی رویشی اروپا - سیبری/ مدیترانه‌ای، ۳ گونه به نواحی رویشی مدیترانه‌ای/ ایرانی -تورانی، 46 گونه به بیش از دو ناحیۀ رویشی تعلق دارند و 20 گونه جهان‌وطن هستند.

Abstract
Wetland plants are often the most conspicuous component of wetland ecosystems. They are grouped into hydrophytes, helophytes, and hygrophytes. In this research, the wetlands flora of Hamedan province, including natural and artificial wetlands, permanent and seasonal rivers and streams and wet mountain meadows, were studied. The results of this study showed that the flora of the wetlands of Hamedan province consisted of 45 families, 111 genera and 163 species. And, 13 families of these plants belonged to monocots, 31 families to dicots and 1 family to the pteridophyta. Families of Asteraceae with 15 genera and 20 species; Poaceae with 19 genera and 23 species, Cyperaceae with 8 genera and 19 species were the largest families of wetlands in Hamadan province. In terms of their life forms, the wetland plants of Hamedan province consisted of 8 species of hydrophytes, 51 species helophyte, 35 species of geophytes, 50 species of hemicryptophytes, 14 species of therophytes,
4 species of phanerophytes, and 1 species of chamaephytes. The chorology of species showed that 29 species of the wetland plants of Hamedan Province belonged to the European-Siberian elements, 38 species to the Iranotouranin elements, 1 species to the Mediterranean elements, 24 species to European-Siberian-Iranotouranin elements, 2 species to Euro-Siberian-Mediterranean elements,
3 species to the Mediterranean-Iranotouranin elements, 46 species to more than two elements, and 20 species to cosmopolitan.
