زمینه و هدف: آگاهی از میزان تغییرات شیمیایی آبهای زیرزمینی و پهنهبندی آنها نقش مهمی در مدیریت بهینه آب های زیرزمینی یک منطقه ایفا میکند. روشهای مختلفی برای مطالعه و پهنهبندی ویژگیهای شیمیایی آبهای زیرزمینی وجود دارد که انتخاب روش مناسب بسته به هدف، شرایط منطقه و وجود آمار و اطلاعات دارد. روشهای زمینآماری وGIS میتوانند در این راستا ابزار مفیدی باشند. هدف از این تحقیق بررسی تغییرات مکانی کیفیت آب زیرزمینی و انتخاب بهترین روش پهنه بندی جهت مدیریت منابع آب زیرزمینی دشت سگزی است. روش بررسی: در این مقاله، توزیع آلایندههای کیفیpH, TDS, Hco3, EC, Ca, Mg, TH, Na وSo4 در سطح آبهای زیرزمینی دشت سگزی شهرستان اصفهان با استفاده از روش معین عکس فاصله و روشهای زمینآماری تخمینگر توابع شعاعی، تخمینگر موضعی، تخمینگر عام و روش کریجینگ معمولی در نرمافزارARCGIS9.3 مورد ارزیابی قرار گرفت. بر این اساس نمونههای آب زیرزمینی 445 چاه، چشمه و قنات مورد بررسی قرار گرفت. پس از بررسی واریوگرام و مشخص شدن مکانی بودن تغییرات پارامترهای مورد بررسی، اقدام به میانیابی پارامترها شد و با استفاده از فن ارزیابی متقابل و ریشه دوم میانگین مربع خطا، بهترین مدل ارزیابی با کمترین مقدار RMSE انتخاب شد. یافتهها: نتایج نشان داد که کلیه پارامترها با استفاده از روش کریجینگ معمولی کمترین مقدار RMSE را داشته است و جهت تهیه نقشه توزیع مکانی پارامترهای کیفیت آب زیرزمینی از این روش استفاده شد. نتایج پهنهبندی نشان داد که پارامترهای Na, Ca, Mg, So4, Hco3, pH به لحاظ شرب بدون محدودیت و پارامترهای EC, TH وTDS محدودیت ایجاد کردهاند. نتایج بیانگر استفاده بیش از حد منابع آب زیرزمینی منطقه مورد مطالعه است. نتیجه گیری: با توجه به نتایج استفاده از کریجینگ معمولی به دلیل دقت بیشتر و محاسبات کمتر در بین روشهای مختلف درونیابی برای پهنهبندی کیفیت آب زیرزمینی توصیه میشود. همچنین مدیریت منابع آب با استفاده از نتایج تحقیق قابل دسترس خواهد بود.
