چکیده

شرایط امروز زمین و تغییرات به وجود آمده به دلیل توسعه­های زندگی مدرن در بخش­های مختلف، موجب بروز تغییرات کمی و کیفی در منابع آب در مناطق مختلف شده است. به همین دلیل بررسی تغییرات منابع آب به‌ویژه رودخانه­ها به‌عنوان مهم­ترین منابع آب شیرین در دسترس ضرورت می­یابد. در این مطالعه با استفاده از آزمون من-کندال تغییرات کمی-کیفی رودخانه آبسرده واقع در غرب ایران در دوره زمانی ۴۵ ساله (13۹۶-13۵۳) مورد بررسی قرار گرفت. نتایج نشان داد که رودخانه از نظر کمی دچار افت شده که این افت از نظر آماری در سطح 95 درصد معنی دار نبوده است (۳۳/۱Z=-). تغییرات کیفی نیز حاکی از تشدید آلاینده­ها به‌ویژه مقادیر EC با ۹/۳ Z=و TDS با ۸۵/۳Z= داشته که در سطح ۹۹ درصد از نظر آماری معنی­دار بوده است. از طرفی وضعیت کیفیت این رودخانه محدودیتی برای آبیاری و مصارف کشاورزی نداشته است.

چکیده [English]

Todays, the conditions of the earth and it's changing due to the development of modern life have caused quantitative and qualitative changes in water resources in different regions. For this reason, it is necessary to investigate water resources, especially rivers, as the most important parts of available fresh water. Absardeh River located in the west of Iran in a period of 45 years (1974-2017) were investigated using the Mann-Kendall test. The results showed that the river has suffered a quantitative decline, which was not statistically significant at the 95% level (Z=-1.33). Qualitative changes also indicate the intensification of pollutants, especially the values of EC with Z=3.9 and TDS with Z=3.85, which were statistically significant at the 99% level. On the other hand, the quality of this river has not limited irrigation and agricultural uses.
