چکیده
زمینهوهدف:عدم وجود جایگاه مناسب برای دفن و نگهداری زباله در مناطق مختلف گیلان نه تنها باعث از بین رفتن هکتارها جنگل و زمین کشاورزی شده، بلکه سلامت عمومی را نیز با خطرات جدی مواجه کرده است. شهرستان لنگرود نیز به ‌عنوان یکی از نقاط گردشگر پذیر استان گیلان از تبعات زباله در امان نیست، لذا مطالعه حاضر با هدف مکان‌یابی مناطق مستعد جدید دفن بهداشتی پسماند شهری با در نظر گرفتن استانداردهای زیست محیطی در شهرستان لنگرود انجام شد.
موادوروش‌ها:در این تحقیق 20 معیار براساس استانداردهای سازمان حفاظت محیط زیست ایران، سازمان محیط زیست ایالت آلبرتای کانادا، آژانس کنترل آلودگی مینه سوتا و وزارت محیط زیست بریتیش کلمبیا به ‌عنوان معیارهای دخیل در مکان‌یابی مورد استفاده قرار گرفتند. برای ترکیب نقشه معیارها از روش  TOPSISدر محیط نرم‌افزار  ArcGISبهره گرفته شد.
یافته‌ها:پس از طی نمودن مراحل روش TOPSIS و باتلفیق لایه‌هاى به‌ دست آمده در محیط نرم‌افزار ArcGIS،نقشه نهایى مکان‌یابى دفن پسماندهاى شهری درمحدوده مطالعاتى در 5 کلاس (خیلی ضعیف، ضعیف، متوسط، خوب وعالی) طبقه ‌بندى شد.
نتیجه‌گیرى:بر مبنای نتایج به‌دست آمده، 5 محدوده مستعد در جنوب و جنوب غربی شهرستان با بالاترین درجه تناسب و قرار گرفتن در کلاس عالی، به‌عنوان مناطق جدید دفن پسماندهای شهری شهرستان لنگرود پیشنهادمی‌شوند.

ABSTRACT
 
Background & objective: The lack of suitable landfill for storage and disposal of solid wastes in different parts of Guilan has been not only led to deforestation and agricultural lands destruction, but also jeopardized public health. The Langroud County as a tourist destination of Guilan province is also affected by solid wastes. Therefore, the present study aims to locate the new appropriate area for municipal sanitary landfill, taking into account environmental standards in Langroud County.
 
Materials & Methods: In this research, 20 criteria were used in accordance with the standards of the Iranian Environmental Protection Agency, the Alberta State Environmental Authority of Canada, the Minnesota Pollution Control Agency and the British Columbia Environmental Ministry as criteria for locating. TOPSIS method was used in combining the criteria maps in ArcGIS software environment.
 
Results: After passing TOPSIS and combining the layers obtained in the ArcGIS software environment, the final map of urban landfill location within the study area was classified into five classes (very weak, weak, moderate, good and excellent).
 
Conclusion: Based on the results, five prestigious areas in the south and southwest of the city with the highest degree of fit and excellent grade were proposed as new areas of urban solid waste disposal for the city of Langroud.
