چکیده مقاله :
ارزیابی ریسک اكولوژيك، که به منظور ارزیابی طیف گسترده ای از اثرات نامطلوب اکوسیستمهاي در معرض خطر زیست محیطی بهکار می رود، به شدت برای تصمیم گیری در حوزه محیط زیست توصیه می شود. در این مقاله تاریخچه توسعه ارزیابی ریسک اكولوژيكي (EcoRA) بررسی می گردد و چشم اندازی برای مدیریت ریسک و ارزیابی ریسک اكولوژيكي ارائه می شود. براساس این بررسي، مرحله فرموله كردن مشکل در یک چارچوب یکپارچه مشخص، ویژگی های خطر و ارزیابی ریسک، آینده روشني براي ارزیابی ریسک اكولوژيكي به تصویر کشیده شده است. ارزیابی ریسک اكولوژيك منطقه ای نوعی از ارزیابیست که به مطالعه نظری، تحلیلهای عدم قطعیت، استفاده یکپارچه از نرم افزار GIS و ارزیابی ریسک جامع در مقیاس منطقه ای را در آینده نیاز دارد.
EcoRA, which is aimed at appraising a wide range of undesirable impacts on ecosystems exposed to a possible eco-environmental hazard, has been highly recommended for environmental decision-making. In this paper reviews the development history of ecological risk assessment (EcoRA) and presents a perspective for EcoRA and management. In addition, regional EcoRA needs to make further efforts, especially in theoretical study, uncertainty analysis, integrated use of GIS software and comprehensive risk assessment at regional scale in the future work.
