| با توجه به اینکه کیفیت آب شرب در سلامتی انسانها نقش مهمی دارد، باید کیفیت آب آبخوانها بهعنوان اصلیترین منبع تأمین آب شرب تجزیهوتحلیل شود. هدف از مطالعۀ حاضر، بررسی کیفیت آبهای زیرزمینی استفاده‌شده برای شرب در شمال شرقی دشت بیجار با شاخص GQI با استفاده از نرمافزار ArcGIS است. محدودۀ مطالعاتی آبخوان دشت بیجار یکی از آبخوانهای استان کردستان است که منبع آب شرب قسمتی از شهر بیجار و بیش از 12 روستا را تأمین میکند. شاخص کیفیت آب شرب با استفاده از چهار روش GQI، GQI-GA، GQI-FL-GA و GQI-FG برای این آبخوان تهیه شده و سپس، بهمنظور صحت‌سنجی و مقایسۀ نتایج چهار روش یادشده از ضریب همبستگی (r) و جذر میانگین مربعات خطا (RMSE) استفاده شد. بر اساس نتایج بهدستآمده، روش GQI-FL- GA با ضریب همبستگی 89/0 و RMSE 01/0 بهترین نتایج و روش GQI-FG با ضریب همبستگی 86/0 و RMSE 11/ 0 ضعیفترین نتایج را ارائه دادند. بر اساس روش شاخص کیفی آب 2/91 درصد از دشت کیفیت مناسب داشته و 8/8 درصد باقی منطقه که بیشتر بخشهای شمال شرقی (خروجی دشت) بوده و کیفیت قابل قبول دارد. | ||

| Considering the quality of drinking water has an important role in human health, so the quality of aquifers as the main source of drinking water supply should be analyzed. The purpose of this study is to investigate the quality of groundwater used for drinking in the northeast of Bijar plain with GQI index using ArcGIS software. Study area of Bijar plain aquifer is one of the aquifers in the Kurdistan province that provides a drinking water source in a part of Bijar city and more than 12 villages. Drinking water quality index used four methods GQI, GQI-GA, GQI-FL-GA and GQI-FG was prepared for this aquifer and then in order to validate and compare the results of the four methods of correlation coefficient (r) and root mean square Error (RMSE) were used. Based on the obtained results, GQI-FL-GA method with correlation coefficient of 0.89 and RMSE 0.01 showed the best results and GQI-FG method with correlation coefficient of 0.86 and RMSE 0.11 presented the weakest results. According to the water quality index method, 91.2 percent of the plain has suiteble good quality and the remaining 8.8 percent of the region, which is mostly the northeastern parts (plain output) has acceptable quality. | ||
