چکیده

تغییرات تنوع و ترکیب جمعیت پرندگان دو شاخص‌ مهم زیستی و بیان کننده وضعیت سلامت محیط‎زیست هستند، به همین دلیل در زمستان 1392 و بهار 1393 تنوع و ترکیب جمعیت پرندگان جزیره شادی اهواز بررسی شد. این جزیره به پارک شهر تبدیل شده و توسط پلی به ساحل غربی روخانه کارون مرتبط شده است. مساحت آن حدود 7/1 هکتار است. در دو فصل زمستان1392 و بهار1393، 37 گونه پرنده متعلق به 18تیره در جزیره شادی توسط دوربین چشمی10×40 و تلسکوپ با مشاهده مستقیم، شناسایی و با روش Total Count شمارش  و ترکیب جمعیت آن‎ها تعیین شد. مجموع پرندگان شمارش شده در زمستان  1414قطعه با 23 گونه (با تراکم 83 پرنده در هر هکتار) و در بهار 1036 قطعه با 29گونه (با تراکم 61 پرنده در هکتار) با ترکیب جمعیت Ciconiformes  و Passeriformes  بود.  بیشترین تعداد پرنده در  اسفند ماه 688 قطعه و بیشترین تعدادگونه 27گونه در اردیبهشت ماه شمارش شد. تیره حواصلیان Ardeidae با 5 گونه بیشترین تنوع درمقام اول، و 10 تیره Apodidae, Motacilidae, Hirondonidae, Alaudidae, Himantopodidae, Turdidae. Sternidae, Rallidae Motacilidae, و Picnonotidae با یک گونه کم‌ترین تنوع را داشتند. گونه Egretta garzetta  با 437 قطعه از پرندگان کنار آبزی در بهار و Larus ridibundus با 576 قطعه از پرندگان آبزی در زمستان گونه غالب بودند.

چکیده [English]

Fluctuation of diversity and population composition of birds are tow bio-indicators of environmental health. For this reason diversity and population composition of birds of Shady island in Karon River in Ahwaz implemented in winter and spring 2014. Area of the park is 17 hectare and adjoin by a bridge to the west of Karon river coast. During winter and autumn we recognized 37 species of birds by telescope and binocular (10 X 40) which belonged to eighteen family. In winter 1414 individuals belong to 23 species and in spring 1036 individuals belong to 29 species counted by total count method. Average density of birds was 83 individuals in winter and 61 in spring in per hectare. Population compound of birds were Ciconiformes and Passeriformes. Most number of birds counted in January and (688 individuals belong to 27 species) lowest was in April. Ardeidae family with 5 species had highest diversity and 10 Family with one species had lowest diversity. The Egretta garzetta with 437 and Larus ridibundus with 576 individuals were dominant in the Shady island.
