چکیده مقاله :

زمینه و هدف: در مناطق خشک و نیمه خشک پدیده گرد و غبار به طور مکرر اتفاق می­افتد. این پدیده اثرات جدی روی سلامت انسان، فرسایش خاک، بیابان­زایی و حمل و نقل دارد. خشک­سالی یکی از پدیده­های طبیعی است که در اثر کاهش بارش به­وجود آمده و باعث کاهش پوشش گیاهی و افزایش گرد و غبار می­شود. هدف از این تحقیق بررسی ارتباط بین تعداد وقوع گرد و غبار و خشک­سالی اقلیمی می­باشد. روش بررسی: در این تحقیق از شاخص SPI برای محاسبه خشک­سالی استفاده گردید. داده­های مربوط به بارش از سال (2010-1980) و داده­های مربوط به گرد و غبار از سال 2010-2004 مورد تحلیل قرار گرفت. سپس پهنه­بندی گرد و غبار و خشک­سالی در دوره آماری مشترک (2010-2004) با استفاده از روش کریجینگ در نرم افزار ArcGIS صورت گرفت. یافته­ها: نتایج پهنه­بندی تعداد وقوع گرد و غبار و خشک­سالی حاکی از آن است که سال 2008 بیش­ترین تعداد وقوع گرد و غبار (226 واقعه گرد و غبار) و خشک­سالی شدید در سطح استان بوده است. هم­چنین سال 2005 کم­ترین تعداد وقوع گرد و غبار (85 واقعه گرد و غبار) و شرایط ترسالی در سطح استان حاکم بوده است. بحث و نتیجه­گیری: نتایج نشان می­دهد که بین وقوع گرد و غبار با خشک­سالی ارتباطی مستقیم وجود دارد و در سال­هایی که شدت خشک­سالی زیاد یا کم شده، بر تعداد وقوع گرد و غبار نیز افزوده یا از آن کاسته شده است.

چکیده انگلیسی:

Background and Objective: In arid and semi-arid regions dust phenomenon occurs frequently. These phenomenon seriously affects the human health, soil erosion, desertification and transport. Drought is one of the natural phenomena that decrease precipitation, reduce vegetation and increase dust in case study. The purpose of this study was to examine the relationship between the number of dust events and climatic drought. Method: In this study, SPI index was used to estimate drought. Rainfall data for the years 1980-2010 and data of the dust for the years 2004-2010 were analyzed. The zoning dust and drought in the same period (2010-2004) was performed using the Kriging method in ArcGIS software. Findings: The results of zoning the occurrence of dust and drought suggest that the greatest number of dust events (226 dust events) and severe drought happened in the province in 2008. Also, in 2005, the lowest number of dust events (85 dust events) and wet conditions prevailed in the province. Discussion and Conclusion: The results indicate the direct relationship between dust event and drought, and dust event increased or decreased during the years that drought intensity increased or decreased.
