| تغذیه‌گرایی یک مشکل زیست‌محیطی جهانی است که خطری جدی برای حفظ کیفیت آب دریاچه سدها، سلامت انسان و اکوسیستم‌های آبی به‌شمار می‌رود. شاخص‌های تعیین وضعیت تغذیه‌ای توده‌های آبی امکان اتخاذ تصمیم و پیاده‌سازی استراتژی‌های مدیریتی در مورد کنترل تغذیه‌گرایی را فراهم می‌کنند. برای ارزیابی وضعیت تغذیه‌گرایی دریاچه سدعلویان درطی سال‌های 1394 الی 1398 از شاخص‌های TSI و TLI و تجزیه و تحلیل آماری برروی پارامترهای فسفرکل (TP)، نیتروژن‌کل (TN)، کلروفیل.آ (Chl.a) و عمق سکی (SD) استفاده شد. نتایج حاصل از تجزیه و تحلیل پارامترها نشان داد ارزش شاخص TSI کل و TLI کل برای دریاچه در سال 1398 به‌ترتیب 5/53 و 8/4 می‌باشد و به‌این‌ترتیب دریاچه در رده یوتروفیک جای گرفت. TN عامل اصلی حادتر شدن کیفیت آب در فصل بهار بود در حالی که در فصل پاییز TP سهم بیشتری در نزول سطح کیفی آب داشت. علاوه بر این، تفاوت بین شاخص‌ها نشان می‌دهد که در کل دوره آماری مورد مطالعه، فسفر عاملی نیست که بهره‌وری جلبک را محدود کند و مقدار میانگین 8/8 برای نسبت TN/TP تأکید می‌کند که TN عامل محدودکننده تولید اولیه می‌باشد. همچنین بررسی‌ها نشان داد علاوه بر جلبک‌ها که مانع عبور نور به سطوح پایین‌تر دریاچه می‌شوند، کدورت غیرجلبکی نیز می‌تواند رشد فیتوپلانکتون‌ها را تحت تأثیر قرار دهد. روند تغییرات پارامترهای نیتروژن‌کل، فسفرکل و کلروفیل.آ صعودی ارزیابی گردید که ضرورت کنترل پارامترهای مغذی ورودی به مخزن سد علویان جهت حفظ کیفیت آب مخزن را طلب می‌کند. | ||

| Eutrophication is a global environmental problem that poses a serious risk to the conservation of dams lake water quality, human health and aquatic ecosystems. Indicators for determining the nutritional status of water bodies allow to make decision and to implement management strategies for controlling eutrophication. TSI and TLI indices and statistical analysis on phosphorus (TP), nitrogen (TN), chlorophyll.a (Chl.a) and Secchi depth (SD) parameters were used to assess the Eutrophic state of Alaviyan Dam Reservoir during 1394 to 1398. The results of parameter analysis showed that the values of total TSI and total TLI index for the lake in 1398 were 53.5 and 4.8, respectively, and thus the lake was placed in the eutrophic category. TN was the main cause of worsening water quality in spring, while in autumn TP had a greater portion in declining water quality. In addition, the differences between the indices indicate that during the study period, phosphorus is not a factor that limits algal productivity and the mean value of 8.8 for the TN / TP ratio emphasizes that TN is the limiting factor of primary production. Studies also showed that in addition to algae, which block light from passing to lower levels of the lake, non-algal turbidity can also affect the growth of phytoplankton. The parameters of total nitrogen, total phosphorus, and chlorophyll-a. showed increased trend, which requires input nutrient controls into Alaviyan reservoir to preserve the water quality. | ||
