چکیده

طرح انتقال آب از سرشاخه های الموت رود که به منظور تأمین منابع آب کشاورزی دشت قزوین (حوضه مقصد) در مرحله برنامه ریزی و اجرا است، می‌تواند پیامدهای اقتصادی متعددی را در منطقه الموت (حوضه مبدأ) به دنبال داشته باشد. به همین منظور، در این تحقیق اثرات انتقال آب بین حوضه ای فوق بر کاربری اراضی (الگوی کشت)، وضعیت درآمدی کشاورزان (سود ناخالص حاصل از الگوی کشت) و ارزش اقتصادی آب در حوضه مبدأ تحلیل و ارزیابی شد. برای تحقق این هدف، از یک سیستم مدل‌سازی مشتمل بر مدل برنامه ریزی ریاضی مثبت (PMP) و رهیافت تابع تولید با کشش جانشینی ثابت (CES) استفاده شد. داده های موردنیاز مربوط به سال زراعی 93-1392 است که از طریق مراجعه به ادارات ذیربط در استان قزوین جمع آوری شدند. نتایج نشان داد که انتقال بین حوضه ای آب از سرشاخه های الموت رود به دشت قزوین با ایجاد محدودیت 10 تا 40 درصد در عرضه آب آبیاری منجر به کاهش 71/1 تا 52/5 و 17/2 تا 32/6 درصد الگوی کشت، کاهش 58/2 تا 21/8 و 18/3 تا 82/9 درصد سود ناخالص کشاورزان و افزایش 23/3 تا 1/31 و 09/4 تا 0/14درصد ارزش اقتصادی آب آبیاری در مناطق الموت شرقی و غربی می‌شود. در پایان با توجه به نتایج به دست آمده، اجرای طرح انتقال بین حوضه ای آب از سرشاخه های الموت رود به دشت قزوین با در نظرگرفتن ملاحظات اقتصادی در حوضه مبدأ توصیه شد.
