چکیده

شناسایی منبع­ های رسوب و آلاینده ­های متصل به آن و تفکیک سهم کاربری‌ها/پوشش‌های زمین در تولید رسوب ابزاری ارزشمند در اولویت‌بندی مکانی کنش‌های حفاطت خاک در حوزه‌های آبخیز است. این پژوهش با هدف منشأیابی رسوب بستر با روش زمین‌شیمیایی در آبخیز واز در استان مازندران انجام شد. سی نمونه‌ی خاک از پوشش­ های گوناگون زمین که سرچشمه‌ی رسوب بود، و یک نمونه‌ی رسوب بستر از خروجی حوزه برداشته، و 59 عنصر آن با روش ICP-OES اندازه گرفته‌شد. با ترکیب‌کردن آزمون‌های دامنه، کروسکال‌والیس، و تحلیل تابع تفکیک در بسته‌ی FingerPro در نرم‌افزار R، 15 عنصر K،Li ،P ،V ،Cr ،Fe ،Cu ،Ga ،Ge ،Rb ،Sb ،Ba ،Nd ،Ta  و W برای ردیابی بهینه انتخاب شد. نتیجه با شاخص نکویی برازش 78/31 نشان داد که سهم زمین‌های کشاورزی، مرتع، جنگل و کناره های آب‌راه در تولید رسوب بستر به‌ترتیب %2/77، %3/61، %12/14 و %73/84 بود. نتیجه‌ی محاسبه‌ی سهم نسبی هر منبع در تولید رسوب نشان داد که کناره های آب‌راه و مرتع با سهم نسبی 0/43 و 0/0008 % به ازای هر هکتار به‌ترتیب بیش‌ترین و کم‌ترین است.

چکیده [English]

Identification of sediment resources and their associated pollutants and contribution separation of land uses / land cover in sediment production is a valuable tool in spatial prioritization of soil conservation practices at watersheds. The present study was conducted with aim of bed sediment Fingerprinting using the geochemical method in Vaz watershed in Mazandaran Province. Thirty soil samples from different land covers were collected as sediment sources, and a sample of bed sediment at the basin outlet was measured. The geochemical characteristics including 59 elements were measured using ICP-OES. Then, using the combination of range tests, Kruskal-Valis and DFA test in FingerPro package at R software, 15 elements including K, Li, P, V, Cr, Fe, Cu, Ga, Ge, Rb, Sb, Ba, Nd, Ta, and W were selected as the optimal tracers. The results with a goodness index of fit of 78.31 showed that the contributions of agricultural, rangeland, forest, and stream bank lands in the bed sediment yield were with rates of 2.77, 3.61, 12.14, and 73.84 %, respectively. Finally, the relative contribution of each source in sediment yield for each hectare was calculated and the results showed that stream bank and rangeland with the relative contribution of 0.43 and 0.0008 percent for each hectare have the highest and lowest participation in sediment yield, respectively.
