چکیده مقاله :
تخلفات ساختمانی که ناشی از عدم رعایت مقررات شهرسازی هستند، به‌طور فزاینده‌ای در شهرها گسترش یافته و به معضلی بزرگ برای مدیریت شهری تبدیل شده‌اند و کنترل مؤثری برای مقابله با آن‌ها وجود ندارد. هدف اصلی این پژوهش، بررسی الگوهای توزیع فضایی-زمانی تخلفات ساختمانی رخ داده بین سال‌های 1400 و 1401 در سطح شهر اردبیل است و تلاش دارد با بررسی این تخلفات، به بهبود برنامه‌ریزی و سیاست‌گذاری شهری کمک کند. این پژوهش کاربردی و توصیفی- تحلیلی با استفاده از آمار فضایی و سامانه اطلاعات جغرافیایی (GIS)، به تحلیل فضا-زمانی تخلفات ساختمانی پرداخته و جامعه آماری، تعداد تخلفات ساختمانی کمیسیون ماده 100 شهرداری اردبیل می‌باشد که به تعداد 23897 مورد و در مناطق پنجگانه شهرداری اردبیل ثبت شده است. برای شناسایی و درک الگوی مکانی تخلفات ساختمانی، از تکنیک‌های میانگین نزدیکترین همسایگی، میانگین مرکزی و منحنی انحراف استاندارد، تحلیل لکه‌های داغ، شاخص موران جهانی و تحلیل تراکم کرنل در سیستم اطلاعات جغرافیایی استفاده شده است. متغیر مورد بحث در این پژوهش، توزیع فضایی تعداد و فراوانی تخلفات ساختمانی ثبت شده می‌باشد. مطالعه حاضر با بررسی توزیع فضایی تخلفات ساختمانی ثبت‌شده در کمیسیون ماده 100 شهرداری اردبیل، نشان می‌دهد که این تخلفات به‌طور معناداری به‌صورت خوشه‌ای در مناطق مرکزی و جنوبی شهر، به‌ویژه مناطق 2 و 3 که از نظر مالی در وضعیت بهتری نسبت به سایر مناطق قرار دارند؛ تمرکز دارند و برای کاهش تخلفات و بهبود مدیریت شهری، نیاز به برنامه‌ریزی دقیق‌تر و نظارت مؤثرتر بر ساخت‌وسازها ضروری است.
چکیده انگلیسی :
Building violations arising from non-compliance with urban planning regulations have increasingly expanded in cities, becoming a significant challenge for urban management. Currently, there are no effective measures in place to control these issues. This study aims to analyze the spatio-temporal distribution patterns of building violations occurring between 2021 and 2022 in Ardabil city. The goal is to support improved urban planning and policymaking by examining these violations. This research is applied and descriptive-analytical, employing spatial statistics and Geographic Information Systems (GIS) for the analysis. The study's sample includes 23,897 building violations recorded by the Article 100 Commission of the Ardabil Municipality, spanning the city’s five districts. To identify and understand the spatial patterns of these violations, various GIS-based techniques such as nearest neighbor analysis, mean center, standard deviational ellipse, hot spot analysis, global Moran's index, and kernel density estimation are used. The primary focus of this research is the spatial distribution of the number and frequency of recorded building violations. The results demonstrate that these violations are significantly clustered in the central and southern areas of Ardabil, particularly in districts 2 and 3, which are more financially affluent than other regions. The findings suggest that reducing building violations and enhancing urban management require more precise planning and stronger oversight of construction activities.
