ایسنا/خراسان رضوی رئیس کمیسیون شهرسازی و معماری شورای اسلامی شهرمشهد گفت: در حال حاضر دشت مشهد جزء مناطقی از کشور است که فرونشست زمین در آن به مرحله بحرانی رسیده است.

حمید ضمیری در خصوص راهکارهای جلوگیری از مخاطرات و عواقب فرونشست زمین در شهر، اظهار کرد: یکی از مشکلاتی که در چند سال اخیر به مشکلات کشور اضافه شده، بحث فرونشست زمین در شهر بوده است.

وی ادامه داد: بسیاری از دشت‌های کشور با این معضل دست و پنجه نرم می‌کنند و به تازگی مخاطرات آن را از نزدیک لمس کرده‌اند.

رئیس کمیسیون شهرسازی و معماری شورای اسلامی شهرمشهد بیان کرد: دشت مشهد جزء مناطقی از کشور است که فرونشست زمین در آن به مرحله بحرانی رسیده و بسیاری از پروژه‌های عمرانی آن را با مشکل مواجه کرده است؛ فرونشست در خط راه آهن تهران_ مشهد یکی از نمونه‌های بارز مخاطرات فرونشست در این استان است.

ضمیری خاطرنشان کرد: بر اساس تحقیقات صورت گرفته توسط کارشناس ارشد ژئومورفولوژی در برنامه‌ریزی محیطی، مهم‌ترین عامل فرونشست در دشت مشهد، برداشت بی رویه و بیش از حدمجاز آب زیرزمینی و ممانعت از نفوذ آب برگشتی شرب، صنعت و کشاورزی به دشت بوده است.

به گزارش پایگاه اطلاع رسانی شهرداری مشهد، وی تصریح کرد: این پدیده به صورتی است که شما ۳۰ سال از منابع آب زیرزمینی برداشت غیرمجاز کرده‌اید و سپس آرام آرام عارضه ایجاد می‌شود و اگر آن را مدیریت کنید، نرخ فرونشست اندک اندک کاهش می‌یابد؛ یعنی اگر روزی به آن نقطه در کشور برسیم که استفاده از منابع آب زیرزمینی کاهش چشمگیری پیدا کند، می‌توان گفت که بعد از ۵ تا ۱۰ سال بعد، فرونشست به تدریج کاهش پیدا خواهد کرد.

رئیس کمیسیون شهرسازی و معماری شورای اسلامی شهر مشهد بیان کرد: موضوع کاهش فرونشست زمین در دشت مشهد همیاری و همکاری همه جانبه دستگاه‌های اجرایی را در سطح شهر و استان می‌طلبد.
